25 Awesome STEM Activities For Preschoolers

What do you think of when you hear the term  STEM preschool activities?  Sounds crazy, like the debates about kindergarten being the new first grade. So why STEM for preschoolers, and what activities are considered STEM in early childhood? Find out below how preschool STEM activities are easy and make for fantastic, playful learning.

What Is STEM?

STEM stands for science, technology, engineering, and math. Some people also include art and call it STEAM! We put together a huge resource guide to understanding STEM with tons of ideas and information to get you started, whether at home or in the classroom.

ALSO CHECK OUT: STEAM Activities For Kids

Why STEM Activities for Preschoolers?

We love participating in simple STEM activities at home, and my son always enjoys them when they are presented at school. Here’s our list of reasons STEM is so valuable for preschoolers…

• Kids need time to wander around, explore nature, and make observations.
• Preschoolers love to build block cities, humongous towers, and crazy sculptures.
• They need free access to blank paper and various art tools to explore colors and textures.
• Preschoolers want to play around with loose parts and create neat patterns.
• They need the opportunity to mix potions and get messy.

Can you see the hints of science, engineering, math, and art in all those things? That’s what makes an activity great for preschool STEM and STEAM!

The youngest kids already know so much about ecology, geology, physics, chemistry, and astronomy. YOU just don’t realize it yet. All they need to know comes from exploring the world around them.

The best thing adults can do with preschool STEM is to stand back and observe. Maybe offer up a question or two to encourage more exploration or observation. But please, please don’t lead your kids step by step!

Allowing your kids to engage in a STEM or STEAM-rich environment provides them with immense opportunities for personal growth. Additionally, it encourages self-confidence, which turns into leadership down the road.

Empower Your Kids With STEM

We need innovators, inventors, engineers, explorers, and problem solvers. We don’t need more followers; instead, we need kids who will take the lead and solve the problems that no one else has solved.

And that starts with preschool STEM activities that allow kids to be kids and allow them to play and explore out of their seats joyfully.

So if you hear the word preschool STEM curriculum and you really feel like you want to roll your eyes, just remember adults like to make big titles. Your kids will adore preschool STEM activities because of the freedom they will provide.

It’s a win/win situation for adults and kids and, ultimately, the entire world. So, what type of preschool STEM activities will you share with your kids?

What Do You Need For Preschool STEM?

There are no specific tools, toys, or products that you must have to create fantastic preschool STEM activities. I guarantee that you have everything you already need!

Of course, there are always a few fun things you can add to a STEM kit and always have on hand. But I encourage you to look for those things first around the house or classroom.

21 Easy Science Activities for Preschoolers

Introduce science concepts to your preschool classroom with these activities and experiments.

• brightwheel
• Child development

Preschoolers may not fully understand science concepts yet, but doing science experiments is an excellent way to lay a foundation for future learning and exploration. Experimentation helps young children build a good relationship with science by making concepts fun and hands-on. 

In this article, we’ve featured simple experiments to teach preschoolers basic science concepts. But before getting into our list, let's discuss why science activities are important and what concepts children need to learn at this stage.

What are important science concepts for a preschooler to learn?

There are seven basic preschool science concepts. They include:

• Observing: This is the first concept children learn from science experiments. For example, when you present them with an object, they are able to use their senses to describe its color, size, shape, and texture. 
• Comparing: Once your preschoolers learn to observe items, you can introduce several items for them to compare. For example, which apple is bigger? Are the colors different? 
• Classifying: After observing and comparing, preschoolers can progress to grouping items. They can arrange things according to shape, size, texture, or color.  
• Measuring:  This is a more advanced skill, where preschoolers can practice measuring items for comparison instead of simply comparing the objects through observation. For example, they can use a weighing scale or tape measure to determine which banana is bigger. 
• Communicating:  After doing experiments, preschoolers have to learn how to report their results. This can be done through documentation, drawing, or verbal description. 
• Inferring:  Children can learn this skill through simple experiments in the classroom. For example, if your class has a thriving plant that you water consistently, the children might notice it has withered after school has been closed for an extended period of time. The children might come to the conclusion that the plant needs water. 
• Predicting:  This skill is gained by making guesses based on prior observations. Preschoolers will start by predicting easy concepts, like what melts or what floats, and advance as they learn more.

Importance of science experiments in early childhood

When children conduct experiments, they learn to observe, predict, and question the world around them, laying the foundation for analytical thinking. These hands-on activities also provide invaluable opportunities for children to experience the thrill of discovery firsthand, encouraging them to be active participants in their own learning process. Here we discuss more benefits of introducing science in preschool:

Fuels curiosity 

As an early childhood teacher, you are most likely bombarded every few minutes with questions about why things happen. Science allows children to investigate and learn more about the world around them. Encouraging children to engage in exploratory activities can help feed curiosity and even reduce the occurrences of challenging behavior. For example, a paint-mixing activity can help neutralize high energy and avoid distracting behavior.

Enhances the curriculum 

Science doesn't have to stand on its own—other parts of the preschool curriculum can be tied to science concepts. For example, during a temperature measuring experiment, children can practice number recognition. You can also extend the lesson by discussing arctic animals or the culture of people who live in cold climates. You could even incorporate an art class by deciding to draw arctic animals. 

Boosts literacy development 

Group science experiments can boost children’s communication skills. One way this is done is by discussing predictions or observations. Children must also use their critical thinking skills to predict what to expect from the experiments and express their thoughts about the experiment.

Builds a foundation for learning 

Science experiments foster a positive attitude toward science at an early age. The skills children learn at this stage can help them think critically, improve their problem-solving skills, and understand their world better. Concepts such as animals, plants, weather, and environment can impact a child's perspective of the world around them.

Science activities for preschoolers

Each of the activities listed below is designed to be fun, engaging, and packed with learning opportunities that introduce basic scientific concepts in a way that’s accessible and exciting for young learners.

1. Grow a rainbow

The concept behind this experiment is capillary action , which is the spontaneous flow of liquid into a porous material. However, preschoolers don't need to remember that to enjoy the action. Prepare to see their faces light up as the rainbow travels up the paper towel to make a complete rainbow. It's also a good opportunity for children to learn more about colors.

2. Sink or float 

In this experiment, children are challenged to predict what will sink and what will float . They can then do the experiment with different objects and record their findings. Remember to ask them to note which predictions they got right.

Additionally, when preschoolers use science-related terms, it expands their vocabulary. For example, science introduces them to words like species , lifecycle , habitat , and microscope .

3. Color-changing milk

This experiment is an introduction to the concept of surface tension, and requires only a few simple materials to get started. There are so many color changes during this experiment, so it's an excellent way to introduce preschoolers to observation and communicating their findings. After the experiment, ask the children when the color changes happened and why they occurred.

4. Water absorption

Understanding how different items absorb water is an important concept for children to understand in real life. This experiment will help preschoolers determine what to use when drying a spill and help them understand why they can use a napkin to wipe up a drop of water, but they need a towel to dry themselves after bathing.

5. What melts in the sun?

This is a good way to pass the time on a hot, sunny day and teach your preschoolers about melting points . Pick a mixture of items that can melt and items that don't melt and add them to a muffin tin. You could choose items such as a cube of cheese, ice, a rock, butter, or a coin. Before starting the experiment, ask the children to predict which items they think will melt and record their answers.

Place the tray in the direct sun and wait at least 15 minutes to see what happens to the items and then revisit their predictions to see which ones they got right. Later, ask them to name other items they think would melt.

6. Bubble towers

This bubble blowing activity will probably be one of your children’s favorite experiments. Add water and a few drops of dish soap to a plastic cup and have children blow out through plastic straws to make bubbles. The bubbles will grow and expand and spill over the edges of the cup. See who can create the biggest bubble tower!

7. Hands-on air pressure

Introduce your preschool class to the concept of air pressure with an experiment that gives a visual demonstration of moving an object with just air. Add two kitchen sponges to a plastic bag and place a plastic straw between the two sponges so one end is outside the bag and one is inside the bag. Seal the bag with tape. Blow into the straw to inflate the bag. Place a pom pom or cotton ball on a flat surface in front of the end of the straw and press hard on the sponges and watch the pom pom roll away.

8. Static comb

This easy experiment teaches the basics of static electricity , the friction force caused by the imbalance of positive and negative charges on a surface. The charges build up on the surface until they’re discharged. 

For this activity, take some colored paper and cut it up into small pieces. Scatter the pieces on a table. Grab a plastic comb and hold it over the pieces of paper and see what happens. Next, run the comb against your hair and hold it over the pieces of paper again. The comb will now attract the pieces of paper and they will get attached to the comb.

9. Magic dancing rice

This experiment shows the reactions of acids and bases. You’ll need vinegar, baking soda, a clean container, a spoon, rice, and water. 

Pour a cup of water into the container, then add a teaspoon of baking soda and stir. Sprinkle some rice in the mixture and observe what happens (the rice sinks because it's denser than water). Then add a teaspoon of vinegar to the water. You’ll observe that the vinegar reacts with the baking soda to form carbon dioxide bubbles.  

After a few minutes, the rice rises to the surface of the glass. Once the rice reaches the surface level, the gas is released, and the rice falls to the bottom of the glass, and the process continues to repeat.

10. Strong shapes

This science activity is similar to the game Jenga, and it’s a good way to introduce preschoolers to the concept of weight distribution . The idea is to make bases of different shapes—square, triangle, and cylinder—out of sheets of paper to see how much weight each base can support. Once the bases are ready, you can start stacking items such as books, one by one, on each base to see how it supports the items.

11. Glowing water experiment

This experiment introduces children to electromagnetic waves . For this experiment, you’ll need regular tap water, tonic water, a dark room, a black light, four glasses, fluorescent paint, and a highlighter pen. Fill glass one with regular tap water, glass two with tonic water, glass three with normal water and highlighter ink, and glass four with normal water and fluorescent paint. Put the four glasses in a dark room, place the back light 12 inches away from the glasses, and watch which glasses glow.

You’ll see that glass one doesn’t glow under black light. However, glass two glows brightly because the quinine in tonic water makes invisible ultraviolet rays visible. Glass three glows because highlighter ink contains phosphors, which react to the black light, causing the water to glow. Because fluorescent paint also contains phosphors, glass four will also glow under black light.

12. Egg and toothpaste experiment 

Convincing children to brush their teeth can be a challenge. This experiment presents an opportunity to show preschoolers how toothpaste protects teeth from discoloration.

For this experiment, you’ll need a dark soda like Coca-Cola, toothpaste, black coffee, four glasses, and four raw eggs. Pour black coffee into two glasses and pour the soda into the remaining two glasses. Coat two of the eggs with toothpaste. Place one plain egg in a glass of soda and one with toothpaste into the other glass of soda. Then place one plain egg in a glass of coffee and a coated egg in the other glass of coffee. Allow the setup to rest for at least 24 hours for desired results. 

You should find that the plain egg in the soda glass stains, while the one coated in toothpaste doesn’t. Similarly, the toothpaste-coated egg in coffee doesn’t stain, but the plain egg in the coffee does.  

This happens because when the plain eggs are placed in the liquids, the acidic contents react with the calcium carbonate to form stains. However, when the eggs are covered with toothpaste, the fluoride creates a protective layer around the eggs to prevent the acidic reaction from happening.

13. Ocean in a bottle

This simple experiment introduces children to the concept that water and oil don’t mix. For this experiment , you’ll need a funnel, blue food coloring, cooking oil, water, and a large, clear plastic bottle.  Fill the bottle with water and add several drops of food coloring. Ask your preschoolers to shake the bottle to disperse the food coloring and observe what happens.

14. Leak-proof bag

This experiment is fascinating, even for some adults. Did you know that you can push pencils through a bag full of water without the water spilling out? Well, it’s possible because the bag is made of a long flexible chain of molecules (polymers), so when the pencils enter the bag, molecules form a seal around them. You’ll need sharpened pencils and a gallon-size storage bag for the experiment. Fill the bag halfway with water and poke a pencil straight into one side and through to the other side. Allow the preschoolers to try this with as many pencils as they can.

15. Rain cloud in a jar

This experiment allows preschoolers to understand the idea behind water saturation as well as  explore clouds and rain in an engaging way. It shows children the process through which clouds get thick before the rain falls. 

For this experiment, you’ll need a large jar, pipettes, gel food coloring, and shaving cream. Mix the food coloring with water in a small cup. Fill ¾ of the large jar with water and spray some shaving cream on top to represent a cloud. Ask the children to use the pipettes to squirt the colored water on top of the cream. Soon the colored water will seep down through the cream (cloud) into the water, just like rain!

16. How to keep a tissue dry in water

This activity is a good way to explain how air pressure works. For this experiment, you’ll need a container, cup, water, and tissue. Instruct the children to push the tissue inside the cup and then fill the container with water. Have the children push the cup down into the water while keeping it straight. 

When done properly, no water touches the tissue. This is because the air pushes the water away from the cup. Lastly, instruct the children to place the cup inside the water again, tilting it this time. This lets air escape from the cup, allowing the water to wet the tissue.

17. Disappearing eggshell

This disappearing egg experiment is a good introduction to how different chemical agents react. In this case, the eggshells dissolve because they contain calcium carbonate. The latter dissolves in the vinegar to produce carbon dioxide gas and calcium ions. 

For the experiment, you’ll need a fresh egg, white vinegar, and a 16-ounce mason jar with a lid and ring. Place your egg in the mason jar and fill the jar halfway with vinegar. It’s important not to completely fill the jar, because the build-up of carbon dioxide could cause the jar to burst.  Cover the jar loosely to allow the gas to escape, and let it sit for at least 48 hours.

18. Floating egg

This experiment is a good way to explore the concept of density. You’ll need tap water, table salt, sugar, saline water, four raw eggs, four glass jars, and a tablespoon. Fill four glasses halfway: Fill glass one with water, glass two with salt water, glass three with sugar water, and glass four with saline water. Place an egg in each glass and observe. 

You’ll find that the egg in glass one sinks because the egg is denser than tap water. However, the egg in glass two floats because the salt increases the water’s density. Similarly, the egg in glass three floats. The egg in glass four sinks.

19. Dissolve objects

This experiment will help your preschoolers understand items that dissolve in water . When choosing substances for the experiment, be sure to include substances that won’t dissolve. Sugar, cornmeal, flour, oatmeal, orzo noodles, and colored sprinkles are good substances to consider. Encourage the children to predict which substances will dissolve before starting the experiment and compare the predictions with the results after completing it.

20. Thunderstorm formation

This is an interesting introduction to the concept of convection . Convection is the science behind why thunderstorms are more common during the afternoon when the sun heats up moist air near the land that rises into cold air.

For this experiment, you’ll need water, two cups, a container, and two colors of washable paint or food coloring. You can use red with warm water and blue with cold water.  In one cup, mix cold water and the blue coloring; in the other cup, mix red coloring and warm water. Then pour the cups of colored water at opposite ends of the container of room temperature water. Observe how the red coloring floats while the blue coloring sinks. 

This happens because warm water has a lower density than room-temperature water, while cold water has a higher density than room-temperature water. Eventually, the cold water becomes warm and starts to rise. Conversely, the warm water cools and starts to sink. This process is called convection.

21. Shadow play

This simple activity explores the science of shadows and can be linked to the concept of solar eclipses . O n a sunny day, take the children outside with a variety of objects of different shapes and sizes (e.g., toys, balls, blocks). Discuss how every object casts a shadow when it blocks the light from the sun, similar to how the moon blocks the sun during a solar eclipse.

Encourage the children to experiment with casting shadows in different ways, using their bodies or the objects provided. They can see how the size and position of the object can change the shadow. Link this back to the solar eclipse by explaining how the moon is like the objects the children are using, and it casts a shadow on Earth during an eclipse.

It's time to get to the lab

Encouraging children to participate in science activities sets a strong foundation for an interest in the subject. Integrating science experiments in early education equips children with the skills necessary to navigate and understand the complexities of the world, fostering a sense of wonder and inquiry that will serve them throughout their educational journeys and beyond.

We want to make it easy for you, so make sure you click through to each activity to learn all of our pro tips and information to answer all of those questions your kids are going to ask.

Although we have focused on proving preschool science activities, many of these are actually STEM activities that incorporate not only science, but also some technology, engineering and math. 

No matter which activities you do, remember the most important rule, have fun!

Tips for Doing Preschool Science Experiments

Doing science activities with preschoolers can be a lot of fun, but you also need to always ensure safety first. But guess what? Even that part can be fun! I highly recommend buying children’s lab coats and lab safety glasses (in fun colors!) , for your preschoolers. It not only will help protect your kids, but it taps into children’s imaginations and helps them embrace the idea of being little scientists.

When doing any of these activities, proper adult supervision is required at all times, and ensure you adapt the activities as required to meet children where they are at maturity and ability wise. We want science to be fun and safe!

Another tip, always assume things are going to get messy! Cover areas and work in spaces when you can let kids explore freely without worrying about the mess. For some of these experiments, you can even head outside!

Whether you are at home and doing some homeschool science or looking for some classroom experiments, there are lots of fun science activities you can do with your kids!

Preschool Science and STEM

Magic color changing playdough.

Sure, anyone can make playdough, but why not make magic playdough that changes color? Kids can experiment by exposing the playdough to different colors in this heat reactive experiment. My kids especially loved chilling different shaped items and making patterns in the playdough, then warming it up to see them disappear.

We also have recipes for Magic Moon Dough or Magic Oobleck , if you prefer a different sensory science experiment.

A classic activity to keep the kids entertained and busy having fun and learning. Oobleck is a non-Newtonian Fluid, which means it becomes solid under pressure, then liquifies once the pressure is removed. Kids love playing with Oobleck and learn cool lessons in states of matter. We have lots of different recipes for making Oobleck . This is a great outdoor activity!

Hatching Dino Eggs

This baking soda and vinegar experiment idea came about because I needed to find ways to help my dinosaur obsessed preschooler build their fine motor skills. Chemistry may seem like an advanced topic, but in this Hatching Dino Eggs Science Activity we make it easy and fun! Kids love using syringes and pipettes to make their dino eggs fizz and “hatch” revealing a little dinosaur hidden inside.

Bouncy Egg Experiment

This fun science experiment involves soaking a raw egg in vinegar to dissolve its shell, leaving a bouncy, rubbery egg. It’s a fascinating way to teach children about osmosis and the properties of eggshells. Plus, kids have fun testing their Bouncy Eggs to see how much they can bounce… or break!

Making Water Rise

This experiment was one of the first activities that I did with my kids when they were just tiny where I saw their eyes light up with so much curiosity! In this project, kids learn about creating a vacuum in a simple setup involving a jar, water, and a candle. This How Does Water Rise activity demonstrates basic principles of physics in an easily understandable way. For really little ones, I do this as a demonstration and they watch as I do the experiment, but they can still get involved by using the thermometer to take readings.

Keep It Dry Experiment

This is a really quick and easy experiment that little kids love. Watch their surprise as you immerse a glass in water with paper towel inside… and it stays dry! Then let them do the Keep it Dry experiment themselves.

Frozen Bubbles

If you live in a colder climate, try freezing bubbles outside. It’s a fun way to explore the science of freezing and weather conditions. We share the secret to the perfect frozen bubbles , so you can have success with your little ones.

Not cold enough for frozen bubbles? You can still do some Bubble Science .

Growing Crystals

Growing crystals can be a magical experience for young minds. It is honestly one of my favorite science activities, because the results are so beautiful! This Egg Geode Crystal Growing activity involves simple ingredients and offers a hands-on approach to learning about crystallization and geology.

If you are looking for crystal growing using other ingredients, we explore lots of different options in our Crystal Gnome project or try growing tasty sugar crystals .

This experiment is not only a visual treat but also a great way to learn about chemical reactions and density. Preschoolers will be mesmerized watching the bubbles dance and play in a homemade lava lamp, which can be made in lots of different ways using household items. We share 5 of our favorite Lava Lamp Activities , including glow in the dark versions.

In this captivating Magic Milk science experiment , preschoolers create an explosion of color as they use soap to disrupt the milk’s surface tension. It’s a fantastic way to teach about chemical reactions and surface tension in a mesmerizing way. Play with the fat content of your milk to create new reactions.

Elephant Toothpaste

A classic experiment where a chemical reaction creates a foamy gusher volcano like reaction, is Elephant Toothpaste . This can be easily done at home with common ingredients and is always a hit with kids.

Make sure you head to your local science center when they are doing demonstration days. They often do massive elephant toothpaste experiments with strong chemicals that erupt many feet into the air!

Walking Rainbow Experiment

We totally messed up this experiment the first time we did it, but once we figured it out, the kids were fascinated and loved checking on the progress over a few days. The Walking Rainbow experiment is a beautiful demonstration of capillary action and color mixing, requiring just jars, paper towels, water, and food coloring… just make sure you read my notes to ensure you don’t make the same mistakes I did!

Rainbow Rain

Keep those rainbows going with this pretty Rainbow Rain science activity that replicates rain clouds. A simple and beautiful experiment involving water, shaving cream, and food coloring, perfect for a rainy day activity.

Skittles Experiment

A super easy and colorful experiment using Skittles and water, the Skittles Experiment is always a hit. My kids especially enjoyed creating different designs and patterns. We even made a Starry Night inspired one. This experiment is not only beautiful, but it smells good too!

Does it Float?

In this fun activity, young children can explore the science concepts of buoyancy and density, by testing whether items sink or float. We loved using this project to introduce the scientific method to our little ones.

Helping Your Baby Reach Greater Wonders

7 Engaging Science Experiments for Curious Preschoolers

• Preschool science experiments help young kids learn patience, perseverance, and critical thinking skills. 
• Science experiments teach kids different scientific concepts while promoting scientific literacy.
• Children are naturally curious, so introducing them to science experiments at a young age is a fantastic idea. 

My kids love science experiments, and they helped get us through those long at-home days during the pandemic. Science activities for preschoolers are a great way to teach kids about the world around them and allow them to think outside the box.

Engaging in fun preschool science experiments is a great way to introduce kids to science concepts like chemical reactions and scientific principles. 

Plus, science experiments encourage kids to look at the world differently and are a creative way to spark curiosity. 

Science experiments for preschoolers don’t have to be complicated, and you’ll usually have all the supplies already. But don’t let your kids have all the fun; I promise you’ll enjoy these preschool science activities, too!

Experiment 1: Rainbow Walking Water  

I took advantage of one of my favorite science activities when my kids had the day off from school. Rainbow Walking Water is a fun experiment that helps teach preschoolers about primary and secondary colors.

This experiment is also a great way to introduce the idea of capillary action, which is how water can move up against the force of gravity through a tube or something porous (like the paper towel). This is the same way that water moves up through a plants roots.

Materials Needed:

• Food coloring (red, blue, and yellow)
• Clear plastic cups
• Paper towels 

Steps for Rainbow Walking Water:

• Line seven cups in a row, filling every other cup with about ¾ cup of water. (The plastic cups I had were taller, so I added extra water.)
• Next, add five drops of red food coloring to the first and last cup. Stir the water and food coloring to mix it up.
• Then, add five drops of yellow food coloring to the third cup. 
• Lastly, add five drops of blue food coloring to the fifth cup. 
• Fold a half sheet of a paper towel in half lengthwise and then again.
• Finally, place half of a paper towel in one cup, allowing the other half to lie in the next cup. You’ll continue draping the paper towels over each cup until the seventh cup. 

This experiment requires some patience on the child’s side because it takes time for the color to creep up the paper towel and into the empty cup. My daughter went off and played and would return to check on it. 

However, your kids will enjoy watching the colorful surprise as each color goes from one cup to the next via the paper towels. You can also let your kids write down what they observed in the science experiment, including what happens when the primary colors mix. 

• It’s best to use select-a-size paper towels or cut regular-sized ones in half. 
• While waiting for the experiment to complete, your child can practice mixing colors with the food coloring and water in separate cups. 

Experiment 2: Volcano Eruption

This classic science activity uses baking soda and vinegar to create a mini volcano. Since baking soda and vinegar aren’t harsh chemicals, you don’t have to worry about your little ones’ hands getting wet.

The volcano eruption is an excellent preschool science experiment introducing the concept of chemical reactions. You can explain to your kids that a chemical reaction occurs when baking soda and vinegar create the gas carbon dioxide. 

What I loved about this experiment was that my 7-year-old son wanted to design his own volcano when we were finished. It’s amazing how science can spark such creativity. 

We also did this experiment more than once since each of my kids wanted a turn. 

• Baking Soda
• Jar or bottle 

You can also add food coloring and dish soap for a more “explosive” reaction. 

Steps for Volcano Eruption:

• Put ½ cup baking soda in the bottle 
• Pour a cup of vinegar in (The more vinegar, the bigger the eruption)
• Enjoy the eruption! 
• Perform the experiment on a plate, a plastic bin, or a sink for easy cleanup. 

Experiment 3: Magnetic Exploration

Using different objects, kids can learn about which items are magnetic and record their observations. Kids can learn about the basic understanding of magnetism and the development of categorization skills. 

Magnetic Exploration is a great science activity for kids at home because you can have them search around to find magnetic objects to test. 

In addition to magnetic items, find non-magnetic things like crayons or pencils so your child can see the difference when testing. 

• Various magnets (bar, ring, horseshoe, etc.)
• Non-magnetic items (crayons, pencils, markers)
• Keep an eye on little ones to ensure they don’t put anything in their mouth. 

Experiment 4: Sink or Float

Sink or float is a fun science experiment introducing young children to buoyancy and density. While preschoolers might not know the big words, they’ll soon learn what makes something float or sink. 

Sink or Float is an easy science experiment, using only a sink or large tub and items around the house . You can have your kids guess what they think will sink or float, which helps introduce hypothesis testing and validation.

While water experiments can get messy, they are also more fun for young kids. My boys thoroughly enjoyed running around the house to find objects to test. 

• A large basin of water (sink or tub)
• Various items to test (cork, plastic toys, metal objects, popsicle sticks, etc.)
• Don’t fill your sink or tub to the top. This will help prevent making a mess. 

Experiment 5: Make a Solar Oven 

You can wow kids with this easy experiment! Learning how to make a solar oven is easier than you think, and it’s also one of my son’s favorite science experiments. 

There are several ways to create a solar oven, but the steps here are for a more straightforward one with preschoolers in mind. 

Solar ovens work best on a hot day, so this is one of the best easy preschool science experiments for a summer day. Our chocolate melted fast, so don’t leave it outside too long! My boys thoroughly enjoyed eating the end product. 

• Pizza box or shoe box
• Aluminum foil 
• Chocolate pieces 
• Black construction paper 
• Glue stick or tape
• Plastic wrap 
• Skewer or ruler 

Steps to Make a Solar Oven:

• I used a shoe box and cut the sides of the top off to make it easier to assemble. 
• Next, attach aluminum foil to the inside of the flap on top with tape or glue. 
• I laid the black construction paper on the bottom of the box and added the chocolate pieces. (Of course, my kids asked if they could eat them once they melted.)
• Tape or glue the plastic wrap in the opening above your black construction paper. 
• Prop the aluminum foil piece up with your skewer or ruler. 
• Set outside directly in the sun (preferably on a hot day) and watch your chocolate melt! 
• This solar oven works best on a hot day; otherwise, you’ll likely be waiting a while for things to melt. 
• While your kids wait for the chocolate to melt, discuss how the sun is a heat source and why it won’t work as well on a cloudy day. 

Experiment 6: Easy Bubble Solution

While you can buy bubbles at the store, creating bubble solutions is a simple, fun science project for preschoolers. Also, your little ones will think it’s super cool to make bubbles at home. Remember, science activities for preschoolers don’t have to be challenging to be fun.

This simple science experiment will show preschoolers what happens when corn syrup and soap mix with the water. Have your little ones predict what will happen before you add each.

• 6 cups room temperature water
• ½ cup light corn syrup 
• 1 cup liquid dish soap 
• Empty container with a lid 
• Measuring cups 
• Pipe cleaners to create bubble wands 

Steps to Make Bubbles:

• Mix the corn syrup and water in your container and let your child stir thoroughly. 
• Add the dish soap and stir gently, not allowing suds to form.
• Let the mixture sit uncovered for several hours or overnight before using.
• Twist the pipe cleaners into bubble wand shapes.
• Pour the completed solution into small cups and let your kids dip their wands to begin blowing bubbles. 
• Mix the bubbles outside to prevent spilling inside.
• Don’t use hot water.

Experiment 7: Make Sound Waves 

If you’re looking for a fun activity for your kids that doesn’t require lots of materials, you’ll appreciate the sound waves experiment. 

What I love about this experiment is it takes a tricky scientific concept (sound waves) and turns it into a basic idea to teach children how they work.  

• 4 or 5 glasses 
• Fill your glasses with different amounts of water.
• Have your child tap each glass to hear the low and high pitches. 

Benefits of Science Experiments for Preschoolers

The best science projects for kids are a fun way to explore science at home or in the classroom. Even older kids will enjoy the creativity and hands-on learning experience science experiments bring. 

The National Science Teaching Association 1 1. Early Childhood Science Education. National Science Teaching Association . 2014. https://www.nsta.org/nstas-official-positions/early-childhood-science-education states that from an early age, children have the ability to observe, explore, and discover the world around them.  

Promotes Cognitive Development

Fun science activities are a great way to encourage cognitive development , including working on problem-solving skills enhancement.

In addition, science projects introduce children to the scientific method in a more straightforward form. A 2006 study 2 2. Koerber, S., Sodian, B., Thoermer, C., & Nett, U.. Scientific Reasoning in Young Children: Preschoolers’ Ability to Evaluate Covariation Evidence. Swiss Journal of Psychology . 2006;64(3), 141–152. https://doi.org/10.1024/1421-0185.64.3.141 by Koerber et al. published in the European Journal of Psychology found that preschool-aged children could demonstrate a basic understanding of the hypothesis-evidence relationship. 

Encourages Social and Emotional Growth

When engaging in a preschool science activity with others, kids learn cooperation and teamwork while building patience and perseverance. Children learn quickly that only some experiments go correctly the first time.

Develops Physical Skills

Working on a fun science activity encourages kids to utilize fine motor skills through hands-on activities while working on coordination and control improvement. In addition, outdoor activities for preschoolers help develop gross motor skills necessary to increase their physical skills. 

How can engaging in preschool science experiments help in developing a growth mindset?

Preschool science activities allow children to take risks while understanding their reasoning may not always be accurate. 

While preschoolers are still learning, engaging in science experiments at an early age helps set the foundation for testing, hypothesizing, and figuring things out. 

How does a hands-on science experiment contribute to the language development of preschool children?

Even simple science experiments help preschoolers learn about asking why, what, when, and how and open-ended questions.

According to the National Association for the Education of Young Children 3 3. Méndez, L. I., Lee, T. D., Hegde, A. V., McMillan, V. J., Dixon, J. B., Goodell, S. L., & Stage, V. C.. Let’s Talk: Linking Science and Language Learning in the Preschool Classroom. National Association for the Education of Young Children . 2023. https://www.naeyc.org/resources/pubs/yc/summer2023/linking-science-and-language , science talk is a flexible instructional approach that promotes conversations about science while allowing children multimodal engagement to learn science and language content and skills.

20 Science Projects for Preschoolers

October 6, 2012 by Ana Dziengel 35 Comments

WIZARD’S BREW RECIPE IN PROJECT #3

I used to think science was above the heads of preschool aged children until I became the science parent at my children’s coop preschool and saw just how wrong I was!  Some of the best preschool activities are science related. Preschool age children are inquisitive and open-minded, perfect traits for budding young scientists! Science at a preschool level is a lot of fun, kids are truly mesmerized by chemical reactions, love exploring nature, and jump to build things.

Here are 20 of our favorite  science projects for preschoolers:

This post contains affiliate links to products I love and recommend to my readers.

1. DISCOVERY TUBES

Adults can make these fun tube toys for kids to play with and demonstrate viscosity. Click here for the full project .

2. MILK PAINTING

This project is very popular on the internet and I can see why. The combination of milk, dish soap, and food coloring makes for some color swirling magic! You can even dip paper in the milk to make a milk “print” to keep! See how we did it here.

3. RAINBOW WIZARD’S BREW

The basic recipe for this is originally from The Usborne Big Book of Science Things to Make and Do , a book I highly recommend you have in your library, there are many more fun ideas like this one! We modified it to give it a rainbow twist!

RAINBOW WIZARD’S BREW

Ingredients:

• Baking Soda
• Liquid Watercolors or Food coloring
• Small plastic containers

Instructions:

Fill the jar halfway with vinegar, then add a few drops of one color of liquid watercolor /food coloring and some glitter. Squeeze in some dish soap, stir, and place the jar on a tray. Now have your child add in a heaping teaspoon of baking soda, stir again, and watch the foaming begin! The soap makes it foam rather than fizz. To keep the reaction going continue adding baking soda and vinegar when the foam starts to slow. To make it change colors, add a tablespoon of vinegar mixed with one color of liquid watercolor/food coloring every so often. Make sure to dump the colored vinegar into the center of the brew.

Tip: Stir It! My kids discovered that the more they stirred the mixture the faster and crazier the reaction! Did you hear the screams of delight in the video?

For many of these and more easy science for kids  get our Printable Science Activity Card Pack here :

4. LEMON VOLCANOES

This easy science activity for kids also smells incredible! Make lemon volcanoes and watch the chemical reaction of citric acid and baking soda.

5. PINECONE BIRDFEEDER

These can be made with any number of “adhesives” meaning any type of nut butter or in this case Crisco! See our full tutorial here.

6. GELATIN STREAKING

This is one of those crazy fun project kids LOVE! Use pipettes and brain molds and turn preschoolers into “brain surgeons.” It’s a great lesson on colloids and a sensory powerhouse to boot.

  7. OOBLECK

AKA slime made with cornstarch and water. This is so much fun, even for the parents! It is very messy so please do it outside or in an easily cleanable place in your home. Add colors to the mix for swirling magic!

8. BUTTERFLY FEEDERS

My kids love butterflies! We have made Butterfly Feeders two ways:

Nectar Version: Instructions here.

Fresh fruit version:.

Supplies:  Small paper plate or plastic lid, yarn, over-ripe fruit, orange juice, flowers, tape

Punch holes near the edges of a small paper plate or plastic lid. Tie yarn through the holes (have your child feed the yarn through the holes for a fine motor skills bonus), then gather and tie the yarn at the top as if this is a hanging plant. Have your child pick some flowers and tape them to the yarn. Add a piece of fresh fruit in the middle of the plate, pour a little juice on top, and hang in a place where you can see it. Admittedly it rained the day after we made these at school and our poor feeder was pretty thrashed, so I never saw a butterfly actually visit it. But most of the fun is in the making!

9. DANCING SPAGHETTI

Super simple project you can do with a couple of items from your pantry. Mix water with baking soda in a clear glass or cup, and add a few small pieces of spaghetti to the mix. Then add vinegar. Bubbles will form on the spaghetti and make it “dance.” Additional instructions can be found here.

10. FLOATERS & SINKERS

Another classic experiment. Fill a large bowl, kiddie pool, or water table with water. Collect a variety of objects that sink and float. Make sure to collect objects that are similar in size but vastly different in density, like a rock and a tennis ball. Ask your child to predict whether the object will sink or float and let them drop it in the water. Have your child classify them into two different stacks, the “Floaters” and the “Sinkers.” Sounds simple but trust me, it’s a hit with preschoolers!

11. SHINY PENNIES

This is a classic experiment and one that easily pleases preschoolers. Collect dirty tarnished pennies and have the kids soak them in a small bowl of vinegar with a teaspoon of salt. Within a minute the pennies will be instantly “shined”. For an added bonus, rinse some of the pennies in water after the vinegar dip and then compare them to the vinegar only pennies; if you wait an hour the vinegar pennies will start to oxidize and turn green.

VARIATION: Experiment with other solutions to shine the pennies. You can try salsa (the acid in tomatoes also acts to clean the pennies), lemon juice, soap and water, and vinegar and see which one works the best.

12. FLUFFY SLIME

This is the best slime recipe for preschool aged kids.  USE THE FLUFFY SLIME RECIPE. It’s easy to make,  a wonderful sensory play activity, and a lesson on Non-Newtonian fluids!

13. seed starts.

Growing things is a very important lesson. I have done two variations on this project, one using cardboard egg cartons and the other using ziploc baggies. The ziplock bag yields the more interesting visual results and the egg carton version makes plants that are much easier to transfer to soil down the road.

• ZIPLOC VERSION: For the ziploc version buy a variety of seeds, beans and corn work well since they are large and easy to pick up. Give your child a folded wet paper towel and have them drop a small amount of seeds on it. Try to leave some space between the seeds if you actually want to plant them, otherwise the roots will tangle. Place the paper towel in a small ziploc bag and hang the bag in a sunny window or outside in a sunny spot. Within a few days the seeds will germinate and the roots will be visible.
• EGG CARTON VERSION:  We love this method because the egg carton cups can be transferred directly to the soil. See how we did it on PBS Parents.

14. MARBLE RUN

Another favorite by all! Don’t throw away your paper towel and toilet paper rolls, use them to make a marble run! This is great collaborative project for kids. Have children sit in a circle an invite them up one at a time to add and test a section of the marble run.

15. RECYCLING SCAVENGER HUNT

Kids love scavenger hunts. Period. If you take the time to set up one related to a specific idea it can be a learning exercise. Since preschoolers for the most part can’t read, I create visual lists with images pulled off the web. For a recycling themed scavenger hunt I divided up items into three categories: compostables, recyclables, and trash. Then I hid these items around the school and gave each child one of the lists attached here: Recycling Scavenger Hunt Sheets . They had a blast finding the items. I re-hid them quite often so they could repeat the hunt.

16. COLOR MIXING

There are so many variations of color mixing projects and kids seem to love every one. Here are three ideas to try:

• Magic Colors! Pour water into three large bowls, then add blue, red, and yellow food coloring to one bowl each. Have an additional color mixing bowl available for your child and a dumping bowl. Give your child two plastic cups and let them experiment with taking a cupful of water from two of the primary colors and pouring them in the mixing bowl. Because the new color appears almost instantly it seems like a magic trick! Dump the third color in the dumping bowl and repeat the experiment. Using light colored or glass bowls makes the new colors more visible.
• Rainbow Spin Mixing Using an old salad spinner you can mix colors by spinning paint! Click here for the full project.
• Color Wheel Playdough Use red, yellow, and blue play dough to mix different shades of colors. Click here for the full project.

17. DANCING BALLOONS

This is a fun interactive project that illustrates the idea of a vortex. And let’s be honest, what preschooler can resist balloons that hover mid air? Project and video available here.

18. LAYERED LIQUIDS

What can I say, kids love mixing liquids togther! You can do this project with common pantry ingredients, messy but worth it! Instructions here.

19. SMELLY GAME

This will be either a hit or a miss in your house depending on if your child can stomach a variety of smells. Yes, there are some stinkers but also some sweet ones. It’s fun to think of things to put in the jars. An alternative is to use yogurt cups covered with a lightweight cloth or with holes poked in the lid. Then you can use actual objects in the containers instead of smells in a liquid form. Printable template and instructions here.

20. ICE  SCULPTURES

Can you melt blocks of ice with salt and warm water? This project was a massive hit at our coop preschool and has even won over some older kids as well! Do this on a hot day!

21. NATURE SHADOW BOXES

This was one of our school year’s all time favorites for parents and kids alike. Check out this post for the full directions! It will take a few days for the glue to dry but then the box can be hung on the wall like a picture!

22. MAGNETIC BOXES

Fill a clear plastic container with metal objects. We used nuts and bolts, pipe cleaners, bobby pins, brads, and paper clips. Hand your child a strong magnet and let them experiment with lifting the objects in the container without touching them. It’s magnetic magic! A great tutorial for making these is on What Do We Do All Day .

23. ELECTRIC PLAYDOUGH

Teach kids how to mix up a batch of playdough then show them how it conducts electricity!

24. OOEY GOOEY OILY ART

A hands-on exploration of  density, polarity, viscosity, and color mixing in this messy fun art project!

I hope you enjoyed this list of our favorite science projects for preschoolers! P.S. my older kids have enjoyed many of these as well!

Thanks Diana!

February 17, 2013 at 8:34 pm

Hi Ana. I have a question about the wizards brew. Do the containers/jars need to be glass for the experiment to work or can a plastic cup suffice?

February 18, 2013 at 7:33 am

Hi Karen, Absolutely you can use a plastic cup. I recommend a clear one so you can see the liquids interact; also a taller one is best as once you add baking soda the whole thing grows exponentially 😉 ! Ana

April 30, 2015 at 1:36 pm

“And as a bonus you don’t have to get into the hard explanations of what is happening, let observations speak for themselves.” That’s exactly the thing that discourages me the most when I find fun “science” experiments. Without the explanation to help kids understand the science behind what’s happening, most of the actual learning is lost. Observation only goes so far. I really like Steve Spangler because he does always tell the kids the WHY when he does fun science stuff, and he’s able to do it in simple language that even young kids can understand. 🙂

April 30, 2015 at 2:19 pm

Hi Alicia, Thank you for your comment, Steve Spangler is one of my favorite sites. I appreciate hearing your point of view and I always try to incorporate simple explanations into the projects I do with kids. But my primary goal in doing science with preschool aged children is getting them excited about the subject in general. I believe that a thoughtful, engaging experience does leave a lasting impression, especially at this age, and I don’t believe it to be a lesson lost. I can’t tell you how many children would run up to me excited to do a science project on Science Day because they had memorable experiences of past experiments. Thanks again for taking the time to express your point of view. Ana

Lovey activity I want to try but is it normal malt vinegar or White vinegar x

June 23, 2015 at 4:27 am

Any vinegar should work but I recommend white because it is inexpensive and you can buy it in large quantities 🙂

Sean Gallaty says

July 10, 2015 at 1:16 am

These are really activities, and not science experiments.

We should demonstrate to the preschoolers what a science experiment is about, which is we take our understanding a form a hypothesis then we test it and make observations, and finally we draw conclusions based on those observations. That’s science.

The last two science experiments that I did with my 5 year old were :

Carbon Dioxide and flame.

We established the fundamental principles of chemical and physical reactions, then we discussed what we knew of the properties of combustion and we hypothesized what would happen if we replaced the oxygen in a container with CO2.

The key here is to get the child to think and follow their own reasoning to come up with an understanding of why the outcome is what it is, and ways to test (not prove, but test) these hypothesis.

First we tested it with baking soda and vinegar, and then we tested it with dry ice. For fun, we threw the rest of the dry ice into water with soap making crazy foam.

Today, we took tarnished pennies and put them in a solution of acetic acid, hydrogen peroxide and sodium cloride. Once we observed and discussed the changes we then extended the experiment by using a car battery charger to electrolytically remove oxidization from the penny and also at the same time, plate the cathode in copper.

All the while we discussed the various states of matter, what a molecule is, what an electron is and the basics of how those things interact.

I gently disagree that a preschooler’s observations explain the science. Science is practice testing theory. Without theory, it’s not science.

July 11, 2015 at 4:05 am

Thank you for your feedback Sean. Sounds like you are having fun with science in your home! My goal with preschoolers is for them to have fun first and to encourage them to be curious. I think we have the same goal but different approaches.

March 8, 2016 at 6:32 pm

Really thanks such a pretty ideas. I liked all here. Science is now more fun for kids and you have proved this in your article

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

DIY Compass

Explore the way magnetism works, and how it affects everyday objects, by magnetizing a needle and making a DIY compass. You can even spin the compass in the water, and it'll end up pointing the right way again.

Paper Bridge

Get the engineering back into STEM with this activity, which challenges kids to create a paper bridge that's strong enough to hold as many pennies as possible. How can they manipulate the paper to make it sturdier? (Hint: Fold it!)

See the paper bridge tutorial at KidsActivities.com »

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Leaf Breathing

It's hard for kids to picture how plants and trees "breathe" through their leaves — until they see the bubbles appear on a leaf that's submerged in water. You can also teach them about photosynthesis by putting different leaves in different spots with varying levels of sunlight.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation

What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking

You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

18 Easy Science Experiments for Kids

By Med Kharbach, PhD | Last Update: June 30, 2024

Effective learning is driven by a sense of motivation, engagement, and challenge. Each of these aspects is interconnected and works symbiotically to create optimal learning experiences. When it comes to science, engagement isn’t always straightforward, and many science teachers still rely on the “storehouse model” (Karen, Roberts & Malcolm, 1991 ), where students are encouraged to store facts for future use.

While the storehouse model might work in certain areas, it doesn’t enhance understanding and critical analysis. Embrace constructionist approaches and hands-on learning to help kids develop inquiry skills and explore the world beyond their textbooks.

Easy Science Experiments for Kids

Science experiments are a fantastic way to embody inquiry skills such as questioning, observing, and reflecting. These hands-on activities encourage kids to become active participants in their learning journey. By engaging in experiments, children learn to ask questions about the world around them, make observations, and reflect on their findings. This process helps them develop critical thinking and problem-solving skills, fostering a deeper understanding of scientific concepts. Needless to mention that these experiments transform the act of learning from passive absorption of information to an active construction of knowledge, making science both fun and educational.

10 of the Best Science Kits for Kids

Things have changed a lot since I was a kid. Science is actually cool now, for example—my kids actually want to learn as much about the world around them as they can, and they can do so in their home with the wide variety of educational kits available to help them learn about geology, physics, paleontology, chemistry, and other branches of study. Not only do these kits give kids a head start in the classroom, but they also impart principles like observing and problem-solving.

If you have an inquisitive kid looking for fun while deepening their understanding of science, here are 10 affordable kits to help them get started. 

Engino Stem Toys: Physics Laws

Sure, your kid can build a rocket with a LEGO set, but it takes science to project it into the air. With  this six-in-one set , your child can make a working launcher, crash test rig, rubber band car, sharpening wheel, bow and arrow, and an inertia test platform while learning basic physics principles. Reviewers say this STEM kit has easy-to-follow instructions that even elementary school-aged kids can understand.

National Geographic Stunning Science Chemistry Set 

We all made model volcanoes for our science fair project, but your kids can take their experiment to the next level with some pop crystals to make it change colors and fizz. That's just one of the many chemistry-based experiments  this kit offers, which also include building a geyser or rocket launcher. The educational instruction booklet also has 30 additional experiments kids can conduct using everyday household items. 

KiwiCo Science of Cooking: Ice Cream

What kid doesn't love ice cream? Now, with this  hands-on kit  created by the popular educational subscription service, they can make their own while learning the materials and methods involved in creating the cold concoction. The kit also includes an illustrated book explaining the science behind the delicious dessert and features recipes for different flavors and sorbet.

Dig a Dozen Dino Eggs 

Studying dinosaurs doesn't mean watching  Jurassic Park  over and over again. Paleontologists have to dig for their discoveries, and your kid can get an idea of what excavating bones is like with  these eggs  with a toy dinosaur hidden inside by using smaller versions of the same tools scientists use. My oldest son loved playing with these when he was younger, but be warned: They can cause a real mess if used indoors. 

Bill Nye's VR Space Lab

The "Science Guy" will immerse your kids in the wonders of the galaxy with a set of goggles that work with an app and smartphone. Activities include over 125 games and engaging augmented-reality experiences that show kids the universe's wonders.  The award-winning toy  also includes crafts, experiments, and a 96-page project book perfect for pre-teens interested in space exploration. 

Mega Cyborg Hand

If only Luke Skywalker had this around when his father cut off his hand! My son built  this 203-piece set (mostly) on his own, so parents can breathe a sigh of relief knowing they don't have to construct this STEM toy entirely on their own. There are no wires or electronics here, either. The hand utilizes pneumatic and hydraulic systems to grip, lift, and move objects. Most importantly, the hand only has four fingers, so your child cannot flip anyone the bird when playing with it. 

Klutz LEGO Gear Bots

This kit  explains the fundamental physics behind the LEGO Technic line with amusing characters, such as an octopus named DJ Bubbles. It includes a book with clear step-by-step instructions, which is important if you've ever tried building a Technic kit.   

5-in-1 Robot Building Set

If your little scientist wants to upgrade DJ Bubbles,  this robot set  is a good next step. They can build a Wall-E knockoff that might upset Disney's lawyers or a robotic dino that is eerily similar to a Dinobot from a particular toy robot-in-disguise line. Appearances aside, commenters love the educational aspects and quality of the toy, while some found it easier to build than others. 

National Geographic Rock Tumbler Set

If your child leans toward geology or wants to make their own jewelry,  this rock tumbler  is the perfect way to uncover the hidden beauty of the Earth. It comes with its own rocks, and while some commenters debate the quietness of the tumbler's three-speed motor, most agree it's easy to use.

Kidzlabs Crystal Science Kit

My first (and only) chemistry set was supposed to help me create crystals through chemical reactions, but it did not include instructions on how to even get started. Thankfully,  this set does , so your kids can create moon crystals and snow trees with the included materials and other common household items. You may need to supervise, though.

Vygotsky’s criticism, based on Piaget’s early work, is hardly applicable to Piaget’s later formulations of his theories – Editor . PSYCHOLOGY owes a great deal to Jean Piaget. It is not an exaggeration to say that he revolutionized the study of child language and thought. He developed the clinical method of exploring children’s ideas which has since been widely used. He was the first to investigate child perception and logic systematically; moreover, he brought to his subject a fresh approach of unusual amplitude and boldness. Instead of listing the deficiencies of child reasoning compared with that of adults, Piaget concentrated on the distinctive characteristics of child thought, on what the child has rather than on what the child lacks. Through this positive approach he demonstrated that the difference between child and adult thinking was qualitative rather than quantitative. Like many another great discovery, Piaget’s idea is simple to the point of seeming self-evident. It had already been expressed in the words of Rousseau, which Piaget himself quoted, that a child is not a miniature adult and his mind not the mind of an adult on a small scale. Behind this truth, for which Piaget provided experimental proof, stands another simple idea the idea of evolution, which suffuses all of Piaget’s studies with a brilliant light. For all its greatness, however, Piaget’s work suffers from the duality common to all the path-finding contemporary works in psychology. This cleavage is a concomitant of the crisis that psychology is undergoing as it develops into a science in the true sense of the word. The crisis stems from the sharp contradiction between the factual material of science and its methodological and theoretical premises, which have long been a subject of dispute between materialistic and idealistic world conceptions. The struggle is perhaps more acute in psychology than in any other discipline. As long as we lack a generally accepted system incorporating all the available psychological knowledge, any important factual discovery inevitably leads to the creation of a new theory to fit the newly observed facts. Freud, L�vy-Bruhl, Blondel, each created his own system of psychology. The prevailing duality is reflected in the incongruity between these theoretical structures, with their metaphysical, idealistic overtones, and the empiric bases on which they are erected. In modern psychology great discoveries are made daily, only to be shrouded in ad hoc theories, prescientific and semi-metaphysical. Piaget tries to escape this fatal duality by sticking to facts. He deliberately avoids generalizing even in his own field and is especially careful not to step over into the related realms of logic, of the theory of cognition, or of the history of philosophy. Pure empiricism seems to him the only safe ground. His book, he writes, is first and foremost a collection of facts and documents. The bonds uniting the various chapters are those that a single method can give to diverse findings – by no means those of systematic exposition [ Language and Thought in the Child p. 1]. Indeed, his forte is the unearthing of new facts, their painstaking analysis, their classification – the ability, as Clapar�de puts it, to listen to their message. An avalanche of facts, great and small, opening up new vistas or adding to previous knowledge, tumbles down on child psychology from the pages of Piaget. His clinical method proves a truly invaluable tool for studying the complex structural wholes of child thought in its evolutional transformations. It unifies his diverse investigations and gives us coherent, detailed, real-life pictures of child thinking. The new facts and the new method led to many problems, some entirely new to scientific psychology, others appearing in a new light. Problems gave birth to theories, in spite of Piaget’s determination to avoid them by closely following the experimental facts and disregarding for the time being that the choice itself of experiments is determined by hypotheses. But facts are always examined in the light of some theory and therefore cannot be disentangled from philosophy. This is especially true of facts relative to thinking. To find the key to Piaget’s rich store of data we must first explore the philosophy behind his search for facts – and behind their interpretation, which he presents only at the end of his second book [ Judgment and Reason in the Child ] in a resume of its contents. Piaget approaches this task by raising the question of the objective interrelatedness of all the characteristic traits of child thinking he observed. Are these traits fortuitous and independent, or do they form an orderly whole, with a logic of its own, around some central, unifying fact? Piaget believes that they do. In answering the question, he passes from facts to theory, and incidentally shows how much his analysis of facts was influenced by theory, even though in his presentation the theory follows the findings. According to Piaget, the bond uniting all the specific characteristics of child logic is the egocentrism of the child’s thinking. To this core trait he relates all the other traits he found, such as intellectual realism, syncretism, and difficulty in understanding relations. He describes egocentrism as occupying an intermediate position, genetically, structurally, and functionally, between autistic and directed thought. The idea of the polarity of directed and undirected thought is borrowed from psychoanalytical theory. Piaget says: Directed thought is conscious, i.e., it pursues aims that are present in the mind of the thinker. It is intelligent, i.e., it is adapted to reality and strives to influence it. It is susceptible of truth and of error ... and it can be communicated through language. Autistic thought is subconscious, i.e., the goals it pursues and the problems it sets itself are not present in consciousness. It is not adapted to external reality but creates for itself a reality of imagination or dreams. It tends, not to establish truths, but to gratify wishes and remains strictly individual and incommunicable as such by means of language, since it operates primarily in images and must, in order to be communicated, resort to roundabout methods, evoking, by means of symbols and of myths, the feelings that guide it [ Language and Thought in the Child , pp. 59-60]. Directed thought is social. As it develops, it is increasingly influenced by the laws of experience and of logic proper. Autistic thought, on the contrary, is individualistic and obeys a set of special laws of its own. Between these two contrasting modes of thought there are many varieties in regard to their degree of communicability. These intermediate varieties must obey a special logic, intermediate too between the logic of autism and the logic of intelligence. We propose to give the name of egocentric thought to the principal of these intermediate forms [ Language and Thought in the Child , p. 62]. While its main function is still the satisfaction of personal needs, it already includes some mental adaptation, some of the reality orientation typical of the thought of adults. The egocentric thought of the child “stands midway between autism in the strict sense of the word and socialized thought” [ Judgment and Reason in the Child , p. 276]. This is Piaget’s basic hypothesis. It is important to note that throughout his work Piaget stresses the traits that egocentric thought has in common with autism rather than the traits that divide them. In the summary at the end of his book, he states emphatically: “Play, when all is said and done, is the supreme law of egocentric thought [ Judgment and Reason in the Child , p. 323]. The same tendency is especially pronounced in his treatment of syncretism, even though he notes that the mechanism of syncretic thinking represents a transition from the logic of dreams to the logic of thought. Piaget holds that egocentrism stands between extreme autism and the logic of reason chronologically as well as structurally and functionally. His conception of the development of thought is based on the premise taken from psychoanalysis that child thought is originally and naturally autistic and changes to realistic thought only under long and sustained social pressure, this does not, Piaget points out, devaluate the intelligence of the child. “Logical activity isn’t all there is to intelligence” [ Judgment and Reason in the Child , p. 267]. Imagination is important for finding solutions to problems, but it does not take care of verification and proof, which the search for truth presupposes. The need to verify our thought – that is, the need for logical activity – arises late. This lag is to be expected, says Piaget, since thought begins to serve immediate satisfaction much earlier than to seek for truth; the most spontaneous form of thinking is play, or wishful imaginings that make the desired seem obtainable. Up to the age of seven or eight, play dominates in child thought to such an extent that it is very hard to tell deliberate invention from fantasy that the child believes to be the truth. To sum up, autism is seen as the original, earliest form of thought; logic appears relatively late; and egocentric thought is the genetic link between them. This conception, though never presented by Piaget in a coherent, systematic fashion, is the cornerstone of his whole theoretical edifice. True, he states more than once that the assumption of the intermediate nature of child thought is hypothetical, but he also says that this hypothesis is so close to common sense that it seems little more debatable to him than the fact itself of child egocentrism. He traces egocentrism to the nature of the practical activity of the child and to the late development of social attitudes. Clearly, from the genetic point of view, one must start from the child’s activity in order to understand his thought; and his activity is unquestionably egocentric and egotistic. The social instinct in well-defined form develops late. The first critical period in this respect occurs toward the age of 7 or 8 [ Judgment and Reason in the Child , p. 276]. Before this age, Piaget tends to see egocentrism as all-pervading. All the phenomena of child logic in their rich variety he considers directly or indirectly egocentric. Of syncretism, an important expression of egocentrism, he says unequivocally that it permeates the child’s entire thinking, both in the verbal and in the perceptual sphere. After seven or eight, when socialized thinking begins to take shape, the egocentric features do not suddenly vanish. They disappear from the child’s perceptual operations but remain crystallized in the more abstract area of purely verbal thought. His conception of the prevalence of egocentrism in childhood leads Piaget to conclude that egocentrism of thought is so intimately related to the child’s psychic nature that it is impervious to experience. The influences to which adults subject the child are not imprinted on him as on a photographic plate: They are “assimilated,” that is to say, deformed by the living being subjected to them and become implanted in his own substance. It is this psychological substance of the child or, in other words, the structure and the functioning peculiar to child thought that we have endeavored to describe and, in a measure, to explain [ Judgment and Reason in the Child , p. 338]. This passage epitomizes the nature of Piaget’s basic assumptions and brings us to the general problem of social and biological uniformities in psychic development, to which we shall return in Section III. First, let us examine the soundness of Piaget’s conception of child egocentrism in the light of the facts on which it is based. Since Piaget’s conception of child egocentrism is of primary significance in his theory, we must inquire what facts led him not only to accept it as a hypothesis but to put such great faith in it. We shall then test these facts by comparing them with the results of our own experiments. The factual basis of Piaget’s belief is provided by his investigation of the child’s use of language. His systematic observations led him to conclude that all conversations of children fall into two groups, the egocentric and the socialized. The difference between them lies mainly in their functions. In egocentric speech, the child talks only about himself, takes no interest in his interlocutor, does not try to communicate, expects no answers, and often does not even care whether anyone listens to him. It is similar to a monologue in a play: The child is thinking aloud, keeping up a running accompaniment, as it were, to whatever he may be doing. In socialized speech, he does attempt an exchange with others – he begs, commands, threatens, conveys information, asks questions. Piaget’s experiments showed that by far the greater part of the preschool child’s talk is egocentric. He found that from 44 to 47 per cent of the total recorded talk of children in their seventh year was egocentric in nature. This figure, he says, must be considerably increased in the case of younger children. Further investigations with six- and seven-year-olds proved that even socialized speech at that age is not entirely free of egocentric thinking. Furthermore, besides his expressed thoughts the child has a great many unexpressed thoughts. Some of these, according to Piaget, remain unexpressed precisely because they are egocentric, i.e., incommunicable. To convey them to others the child would have to be able to adopt their point of view. “One might say that an adult thinks socially even when he is alone, and a child under seven thinks and speaks egocentrically even in the society of others” [ Language and Thought in the Child , p. 56]. Thus the coefficient of egocentric thought must be much higher than the coefficient of egocentric speech. But it is the data on speech, which can be measured, that furnish the documentary proof on which Piaget bases his conception of child egocentrism. His explanations of egocentric speech and of child egocentrism in general are identical. In the first place, there is no sustained social life among children of less than 7 or 8; in the second place, the real social language of the child, that is, the language used in the basic activity of children – play – is a language of gestures, movements, and mimicry as much as of words [ Language and Thought in the Child , p. 56]. When, at the age of seven or eight, the desire to work with others manifests itself, egocentric talk subsides. In his description of egocentric speech and its developmental fate, Piaget emphasizes that it does not fulfil any realistically useful function in the child’s behavior and that it simply atrophies as the child approaches school age. Our own experiments suggest a different conception. We believe that egocentric speech early assumes a very definite and important role in the activity of the child. In order to determine what causes egocentric talk, what circumstances provoke it, we organized the children’s activities in much the same way Piaget did, but we added a series of frustrations and difficulties. For instance, when a child was getting ready to draw, he would suddenly find that there was no paper, or no pencil of the color he needed. In other words, by obstructing his free activity we made him face problems. We found that in these difficult situations the coefficient of egocentric speech almost doubled, in comparison with Piaget’s normal figure for the same age and also in comparison with our figure for children not facing these problems. The child would try to grasp and to remedy the situation in talking to himself: “Where’s the pencil? I need a blue pencil. Never mind, I'll draw with the red one and wet it with water; it will become dark and look like blue.” In the same activities without impediments, our coefficient of egocentric talk was even slightly lower than Piaget’s. It is legitimate to assume, then, that a disruption in the smooth flow of activity is an important stimulus for egocentric speech. This discovery fits in with two premises to which Piaget himself refers several times in his book. One of them is the so-called law of awareness, which states that an impediment or disturbance in an automatic activity makes the actor aware of that activity. The other premise is that speech is an expression of that process of becoming aware. Our findings indicate that egocentric speech does not long remain a mere accompaniment to the child’s activity. Besides being a means of expression and of release of tension, it soon becomes an instrument of thought in the proper sense – in seeking and planning the solution of a problem. An accident that occurred during one of our experiments provides a good illustration of one way in which egocentric speech may alter the course of an activity: A child of five and a half was drawing a streetcar when the point of his pencil broke. He tried, nevertheless, to finish the circle of a wheel, pressing down on the pencil very hard, but nothing showed on the paper except a deep colorless line. The child muttered to himself, “It’s broken,” put aside the pencil, took watercolors instead, and began drawing a broken streetcar after an accident, continuing to talk to himself from time to time about the change in his picture. The child’s accidentally provoked egocentric utterance so manifestly affected his activity that it is impossible to mistake it for a mere by-product, an accompaniment not interfering with the melody. Our experiments showed highly complex changes in the interrelation of activity and egocentric talk. We observed how egocentric speech at first marked the end result or a turning point in an activity, then was gradually shifted toward the middle and finally to the beginning of the activity, taking on a directing, planning function and raising the child’s acts to the level of purposeful behavior. What happens here is similar to the well-known developmental sequence in the naming of drawings. A small child draws first, then decides what it is that he has drawn; at a slightly older age, he names his drawing when it is half done; and finally he decides beforehand what he will draw. The revised conception of the function of egocentric speech must also influence our conception of its later fate and must be brought to bear on the issue of its disappearance at school age. Experiments can yield indirect evidence but no conclusive answer about the causes of this disappearance. Nevertheless, the data obtained strongly suggest the hypothesis that egocentric speech is a transitional stage in the evolution from vocal to inner speech. The older children in our experiments behaved differently from the younger ones when faced with obstacles. Often the child examined the situation in silence, then found a solution. When asked what he was thinking about, he gave answers that were quite close to the thinking-aloud of the preschooler. This would indicate that the same mental operations that the preschooler carries out through egocentric speech are already relegated to soundless inner speech in the schoolchild. There is, of course, nothing to this effect in Piaget, who believes that egocentric speech simply dies off. The development of inner speech in the child receives little specific elucidation in his studies. But since inner speech and voiced egocentric speech fulfil the same function, the implication would be that if, as Piaget maintains, egocentric speech precedes socialized speech then inner speech also must precede socialized speech an assumption untenable from the genetic point of view. The inner speech of the adult represents his “thinking for himself” rather than social adaptation; i.e., it has the same function that egocentric speech has in the child. It also has the same structural characteristics: Out of context, it would be incomprehensible to others because it omits to “mention” what is obvious to the “speaker.” These similarities lead us to assume that when egocentric speech disappears from view it does not simply atrophy but “goes underground,” i.e., turns into inner speech. Our observation that at the age when this change is taking place children facing difficult situations resort now to egocentric speech, now to silent reflection, indicates that the two can be functionally equivalent. It is our hypothesis that the processes of inner speech develop and become stabilized approximately at the beginning of school age and that this causes the quick drop in egocentric speech observed at that stage. Limited in scope as our findings are, we believe that they help one to see in a new and broader perspective the general direction of the development of speech and thought. In Piaget’s view, the two functions follow a common path, from autistic to socialized speech, from subjective fantasy to the logic of relationships. In the course of this change, the influence of adults is deformed by the psychic processes of the child, but it wins out in the end. The development of thought is, to Piaget, a story of the gradual socialization of deeply intimate, personal, autistic mental states. Even social speech is represented as following, not preceding, egocentric speech. The hypothesis we propose reverses this course. Let us look at the direction of thought development during one short interval, from the appearance of egocentric speech to its disappearance, in the framework of language development as a whole. We consider that the total development runs as follows: The primary function of speech, in both children and adults, is communication, social contact. The earliest speech of the child is therefore essentially social. At first it is global and multifunctional; later its functions become differentiated. At a certain age the social speech of the child is quite sharply divided into egocentric and communicative speech. (We prefer to use the term communicative for the form of speech that Piaget calls socialized as though it had been something else before becoming social. From our point of view, the two forms, communicative and egocentric, are both social, though their functions differ.) Egocentric speech emerges when the child transfers social, collaborative forms of behavior to the sphere of inner-personal psychic functions. The child’s tendency to transfer to his inner processes the behavior patterns that formerly were social is well known to Piaget. He describes in another context how arguments between children give rise to the beginnings of logical reflection. Something similar happens, we believe, when the child starts conversing with himself as he has been doing with others. When circumstances force him to stop and think, he is likely to think aloud. Egocentric speech, splintered off from general social speech, in time leads to inner speech, which serves both autistic and logical thinking. Egocentric speech as a separate linguistic form is the highly important genetic link in the transition from vocal to inner speech, an intermediate stage between the differentiation of the functions of vocal speech and the final transformation of one part of vocal speech into inner speech. It is this transitional role of egocentric speech that lends it such great theoretical interest. The whole conception of speech development differs profoundly in accordance with the interpretation given to the role of egocentric speech. Thus our schema of development first social, then egocentric, then inner speech – contrasts both with the traditional behaviorist schema – vocal speech, whisper, inner speech – and with Piaget’s sequence – from nonverbal autistic thought through egocentric thought and speech to socialized speech and, logical thinking. In our conception, the true direction of the development of thinking is not from the individual to the socialized, but from the social to the individual. It is not possible within the limits of the present study to evaluate all aspects of Piaget’s theory of intellectual development; our interest focuses on his conception of the role of egocentrism in the developmental relationship of language and thought. We shall, however, point out briefly those of his basic theoretical and methodological assumptions which we consider erroneous, as well as the facts he fails to take into account in his characterization of child thinking. Modern psychology in general, and child psychology in particular, reveal a tendency to combine psychological and philosophical issues. A subject of the German psychologist Ach aptly summarized this trend when he remarked at the end of a session, “But that is experimental philosophy!” And indeed many issues in the complex field of child thinking border on the theory of cognition, on theoretical logic, and on other branches of philosophy. Time and again Piaget inadvertently touches upon one or another of these but with remarkable consistency checks himself and breaks off. Yet in spite of his express intention to avoid theorizing, he does not succeed in keeping his work within the bounds of pure factual science. Deliberate avoidance of philosophy is itself a philosophy, and one that may involve its proponents in many inconsistencies. An example of this is Piaget’s view of the place of causal explanation in science. Piaget attempts to refrain from considering causes in presenting his findings. In doing so, he comes dangerously close to what he calls, in the child, “precausality,” though he himself may view his abstention as a sophisticated “supracausal” stage, in which the concept of causality has been outgrown. He proposes to replace the explanation of phenomena in terms of cause and effect by a genetic analysis in terms of temporal sequence and by the application of a mathematically conceived formula of the functional interdependence of phenomena. In the case of two interdependent phenomena, A and B, A may be viewed as a function of B, or B as a function of A. The investigator reserves the right to organize his description of the data in the way that best suits his purpose at the time, although he will usually give preferential position to the earlier developmental phenomena as being more explanatory in the genetic sense. This substitution of the functional for the causal interpretation deprives the concept of development of any real content. Even though Piaget, in discussing the biological and the social factors, acknowledges that the student of mental development is duty-bound to explain the relation between them and to neglect neither, his solution is as follows: But, to begin, it is necessary to choose one of the idioms to the disadvantage of the other. We have chosen the sociological idiom, but we emphasize that there is nothing exclusive about this – we reserve the right to return to the biological explanation of child thought and to translate into its terms the description we are attempting here [ Judgment and Reason in the Child , p. 266]. This indeed makes Piaget’s whole approach a matter of purely arbitrary choice. The basic framework of Piaget’s theory rests on the assumption of a genetic sequence of two opposite forms of mentation which are described by the psychoanalytic theory as serving the pleasure principle and the reality principle. From our point of view, the drive for the satisfaction of needs and the drive for adaptation to reality cannot be considered separate from and opposed to each other. A need can be truly satisfied only through a certain adaptation to reality. Moreover, there is no such thing as adaptation for the sake of adaption; it is always directed by needs. That is a truism inexplicably overlooked by Piaget. Piaget shares with Freud not only the untenable conception of a pleasure principle preceding a reality principle but also the metaphysical approach which elevates the desire for pleasure from its true status of a biologically important ancillary factor to that of an independent vital force, the prime mover of psychic development. Once he has separated need and pleasure from adaptation to reality, logic forces Piaget to present realistic thought as standing apart from concrete needs, interests, and wishes, as “pure thought” whose function is the search for truth exclusively for its own sake. Autistic thought – the original opposite of realistic thought in Piaget’s scheme – is, – in our opinion, a late development, a result of realistic thought and of its corollary, thinking in concepts, which leads to a degree of autonomy from reality thus permits satisfaction in fantasy of the needs frustrated in life. This conception of autism is consistent with Bleuler’s. Autism is one of the effects of the differentiation and polarization of the various functions of thought. Our experiments brought to the fore another important point overlooked so far: the role of the child’s activity in the evolution of his thought processes. We have seen that egocentric speech is not suspended in a void but is directly related to the child’s practical dealings with the real world. We have seen that it enters as a constituent part into the process of rational activity, taking on intelligence, as it were, from the child’s incipiently purposeful actions; and that it increasingly serves problem-solving and planning as the child’s activities grow more complex. This process is set in motion by the child’s actions; the objects he deals with mean reality and shape his thought processes. In the light of these facts, Piaget’s conclusions call for clarification concerning two important points. First, the peculiarities of child thought discussed by Piaget, such as syncretism, do not extend over quite so large an area as Piaget believes. We are inclined to think (and our experiments bear us out) that the child thinks syncretically in matters of which he has no knowledge or experience but does not resort to syncretism in relation to familiar things or things within easy reach of practical checking – and the number of these things depends on the method of education. Also, within syncretism itself we must expect to find some precursors of the future causal conceptions which Piaget himself mentions in passing. The syncretic schemata themselves, despite their fluctuations, lead the child gradually toward adaptation; their usefulness must not be underrated. Sooner or later, through strict selection, reduction, and mutual adaptation, they will be sharpened into excellent tools of investigation in areas where hypotheses are of use. The second point which calls for reappraisal and limitation is the applicability of Piaget’s findings to children in general. His experiments led him to believe that the child was impervious to experience. Piaget draws an analogy which we find illuminating: Primitive man, he says, learns from experience only in a few special, limited cases of practical activity – and he cites as examples of these rare cases agriculture, hunting, and manufacturing things. But this ephemeral, partial contact with reality does not in the least affect the general trend of his thinking. The same is all the more true of children [ Judgment and Reason in the Child , pp. 268-269]. We would not call agriculture and hunting negligible contacts with reality in the case of primitive man; they are practically his whole existence. Piaget’s view may hold true for the particular group of children he studied, but it is not of universal significance. He himself tells us the cause of the special quality of thinking he observed in his children: The child never really and truly comes in contact with things, because he does not work. He plays with things, or takes them for granted [ Judgment and Reason in the Child , p. 269]. The developmental uniformities established by Piaget apply to the given milieu, under the conditions of Piaget’s study. They are not laws of nature but are historically and socially determined. Piaget has already been criticized by Stern for his failure sufficiently to take into account the importance of the social situation and milieu. Whether the child’s talk is more egocentric or more social depends not only on his age but also on the surrounding conditions. Piaget observed children at play together in a particular kindergarten, and his coefficients are valid only for this special child milieu. When the children’s activity consists entirely of play, it is accompanied by extensive soliloquizing. Stern points out that in a German kindergarten, in which there was more group activity, the coefficient of egocentrism was somewhat lower, and that in the home children’s speech tends to be predominantly social at a very early age. If that is true of German children, the difference between Soviet children and Piaget’s children in the Geneva kindergarten must be even greater. Piaget admits, in his foreword to the Russian edition of his book, that it is necessary to compare the behavior of children of different social backgrounds to be able to distinguish the social from the individual in their thinking. For this reason he welcomes collaboration with Soviet psychologists. We, too, are convinced that the study of thought development in children from a different social environment, and especially of children who, unlike Piaget’s children, work, must lead to results that will permit the formulation of laws having a much wider sphere of application.

Security Council meeting on Monday. The U.S., France, Britain and Germany accused Iran of escalating its nuclear activities far beyond limits it agreed to in a 2015 deal aimed at preventing Tehran from developing nuclear weapons, and of failing to cooperate with the U.N. nuclear watchdog , the International Atomic Energy Agency. Iran and Russia accused the U.S. and its allies of continuing to apply economic sanctions that were supposed to be lifted under the deal, and insisted that Tehran’s nuclear program remains under constant oversight by the IAEA. The clashes came at a semi-annual meeting on implementation the nuclear deal between Iran and six major countries — the U.S., Russia, China, Britain, France and Germany — known as the Joint Comprehensive Plan of Action. Under the accord, Tehran agreed to limit enrichment of uranium to levels necessary for the peaceful use of nuclear power in exchange for the lifting of economic sanctions. Then-President Donald Trump pulled the U.S. out of the deal in 2018. Trump said he would negotiate a stronger deal, but that didn’t happen. The council meeting followed an IAEA report in late May that Iran has more than 142 kilograms (313 pounds) of uranium enriched up to 60% purity , a technical step away from weapons-grade level of 90%. The IAEA said this was an increase of over 20 kilograms (45 pounds) from February. The IAEA also reported on June 13 that its inspectors verified that Iran has started up new cascades of advanced centrifuges more quickly enrich uranium and planned to install more. U.S. deputy ambassador Robert Wood told the council that the IAEA reports “show that Iran is determined to expand its nuclear program in ways that have no credible civilian purpose.” Wood said the U.S. is prepared to use all means to prevent a nuclear-armed Iran, but said it remains “fully committed to resolving international concerns surrounding Iran’s nuclear program through diplomacy.” The three Western countries that remain in the JCPOA — France, Germany and the United Kingdom — issued a joint statement after the council meeting also leaving the door open for diplomatic efforts “that ensure Iran never develops a nuclear weapon.” They said Iran’s stockpile of highly enriched uranium is now 30 times the JCPOA limit, and stressed that Iran committed not to install or operate any centrifuges for enrichment under the JCPOA. Their joint statement also noted that “Iranian officials have issued statements about its capacity to assemble a nuclear weapon.” Iran’s U.N. Ambassador Amir Saeid Iravani blamed “the unilateral and unlawful U.S. withdrawal from the JCPOA” and the failure of the three European parties to the deal “to honor their commitments,” saying it is “crystal clear” they are responsible for the current non-functioning of the agreement. In the face of U.S. and European sanctions, he said, Iran has the right to halt its commitments under the JCPOA. Iravani reiterated Iran’s rejection of nuclear weapons , and insisted its nuclear activities including enrichment are “for peaceful purposes” and are subject to “robust verification and monitoring” by the IAEA. The Iranian ambassador strongly endorsed the JCPOA, calling it a hard-won diplomatic achievement “that effectively averted an undue crisis.” “It remains the best option, has no alternative, and its revival is indeed in the interest of all of its participants,” he said. “Our remedial measures are reversible if all sanctions are lifted fully and verifiably.” But France, Germany and the UK said some of Iran’s nuclear advances are irreversible. Russia’s U.N. Ambassador Vassily Nebenzia said U.S. promises “to abandon the policy of maximum pressure on Tehran and to return to the nuclear deal remained empty words.” He accused some other JCPOA parties, which he didn’t name, of “doing everything possible to continuously rock the boat, jettisoning opportunities for the implementation of the nuclear deal.” Nebenzia urged the European parties to the agreement and the United States to return to the negotiating table in Vienna and “demonstrate their commitment to the objective of restoration of the nuclear deal.” EU foreign policy chief Josep Borrell, the coordinator of the JCPOA, said the compromise text he put forward two years ago for the U.S. to return to the JCPOA and for Iran to resume full implementation of the agreement remains on the table. 167 COMMENTS 45 Simple and Fun Science Activities for Preschoolers Preschool science experiments often include a combination of baking soda and vinegar like this one.
