44. Make An Ice Magnifying Glass 

This experiment is pretty simple, but we like to add something more fun to it. Once you have made your ice magnifying glass, show your students how glass behaves underwater by designing a real magnifying glass (do not allow them to do this though).

Glass under water can be cut and sliced in much different ways than above the surface, so you can easily create your own glass designs to show your students in a safe way.

45. Can Eggs Float?

Finally, on our list, we have the experiment that has shown students for years how eggs can float on water if salt is added to the liquid. It’s a simple way to explain density, and it’s always a good idea to bring in the Dead Sea example.

The Dead Sea is so salty that people can simply float on its surface, but it’s also deadly because if you turn around – it’s difficult to get your head out of the salty water! 

Things To Remember

There are always things you should remember when it comes to these sorts of experiments. Some are much more obvious than others, but it’s always important to ensure we’re on the same wavelength. These include the following.

Safety 

Conduct a health and safety risk assessment before you carry out any experiment, and always be aware of any safety equipment you and your students may need to wear. Be sure to take reasonable care with all of your experiments (and best to do a trial run first!).

Reinforce Learning 

It’s all fine and good demonstrating the experiments, but you must ensure that you reinforce the student’s learning by asking questions at the end of the lesson. It’s also wise to set some theoretical homework based on their practical experiment. 

Do Your Research 

It’s of course critical that you know exactly what you are doing before you show your students, but it’s also as important to know your students. For example, if an experiment is more tailored for younger students, do not try it for older kids.  You may also like: 1st grade science project ideas .

How To Teach Science

Kids are curious and always looking to explore, discover, check out, and experiment to discover why things do what they do, move as they move, or change as they change! My son is now 13, and we started with simple science activities around three years of age with simple baking soda science.

Here are great tips for making science experiments enjoyable at home or in the classroom.

Safety first: Always prioritize safety. Use kid-friendly materials, supervise the experiments, and handle potentially hazardous substances yourself.

Start with simple experiments: Begin with basic experiments (find tons below) that require minimal setup and materials, gradually increasing complexity as kids gain confidence.

Use everyday items: Utilize common household items like vinegar and baking soda , food coloring, or balloons to make the experiments accessible and cost-effective.

Hands-on approach: Encourage kids to actively participate in the experiments rather than just observing. Let them touch, mix, and check out reactions up close.

Make predictions: Ask kids to predict the outcome before starting an experiment. This stimulates critical thinking and introduces the concept of hypothesis and the scientific method.

Record observations: Have a science journal or notebook where kids can record their observations, draw pictures, and write down their thoughts. Learn more about observing in science. We also have many printable science worksheets .

Theme-based experiments: Organize experiments around a theme, such as water , air , magnets , or plants . Even holidays and seasons make fun themes!

Kitchen science : Perform experiments in the kitchen, such as making ice cream using salt and ice or learning about density by layering different liquids.

Create a science lab: Set up a dedicated space for science experiments, and let kids decorate it with science-themed posters and drawings.

Outdoor experiments: Take some experiments outside to explore nature, study bugs, or learn about plants and soil.

DIY science kits: Prepare science experiment kits with labeled containers and ingredients, making it easy for kids to conduct experiments independently. Check out our DIY science list and STEM kits.

Make it a group effort: Group experiments can be more fun, allowing kids to learn together and share their excitement. Most of our science activities are classroom friendly!

Science shows or documentaries: Watch age-appropriate science shows or documentaries to introduce kids to scientific concepts entertainingly. Hello Bill Nye and the Magic Schoolbus! You can also check out National Geographic, the Discovery Channel, and NASA!

Ask open-ended questions: Encourage critical thinking by asking open-ended questions that prompt kids to think deeper about what they are experiencing.

Celebrate successes: Praise kids for their efforts and discoveries, no matter how small, to foster a positive attitude towards science and learning.

What is the Scientific Method for Kids?

The scientific method is a way scientists figure out how things work. First, they ask a question about something they want to know. Then, they research to learn what’s already known about it. After that, they make a prediction called a hypothesis.

Next comes the fun part – they test their hypothesis by doing experiments. They carefully observe what happens during the experiments and write down all the details. Learn more about variables in experiments here.

Once they finish their experiments, they look at the results and decide if their hypothesis is right or wrong. If it’s wrong, they devise a new hypothesis and try again. If it’s right, they share their findings with others. That’s how scientists learn new things and make our world better!

Go ahead and introduce the scientific method and get kids started recording their observations and making conclusions. Read more about the scientific method for kids .

37 Cool Science Experiments for Kids to Do at Home

General Education

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

• Teaches Kids About: Zoology
• Difficulty Level: Medium
• Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

• Materials Needed
• Shadow box or other box with multiple compartments
• Hot glue gun with glue
• Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

#2: DIY Lava Lamp

• Teaches Kids About: Chemical reactions
• Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

• Vegetable oil
• Food coloring
• Antacid tablets

#3: Magnetic Slime

• Teaches Kids About: Magnets
• Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

• Liquid starch
• Adhesive glue
• Iron oxide powder
• Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

• Teaches Kids About: Chemical reactions, earth science
• Difficulty Level: Easy-medium
• Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

• Baking soda
• Dishwashing detergent
• Large mason jar or soda bottle
• Playdough or aluminum foil to make the "volcano"
• Additional items to place around the volcano (optional)
• Food coloring (optional)

#5: Tornado in a Jar

• Teaches Kids About: Weather
• Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

• Glitter (optional)

#6: Colored Celery Experiment

• Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

• Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

• Glass jar with a lid
• Boiling water
• Aerosol hairspray

#8: Edible Rock Candy

• Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

• Large saucepan
• Clothespins
• String or small skewers
• Candy flavoring (optional)

#9: Water Xylophone

• Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

• Wooden sticks/skewers

#10: Blood Model in a Jar

• Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

• Empty jar or bottle
• Red cinnamon candies
• Marshmallows or dry white lima beans
• White sprinkles

#11: Potato Battery

• Teaches Kids About: Electricity
• Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

• Fresh potato
• Galvanized nail
• Copper coin

#12: Homemade Pulley

• Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

• Clothesline
• 2 clothesline pulleys

#13: Light Refraction

• Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

• Sticky note
• Transparent water bottle

#14: Nature Journaling

• Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

• Blank journal or notebook
• Pens/pencils/crayons/markers
• Tape or glue for adding items to the journal

#15: DIY Solar Oven

• Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

• Aluminum foil
• Knife or box cutter
• Permanent marker
• Plastic cling wrap
• Black construction paper

#16: Animal Blubber Simulation

• Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

• Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

• Tissue paper
• Thick paper
• Glue stick/glue

#18: Edible Double Helix

• Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

• 2 pieces of licorice
• 12 toothpicks
• Small marshmallows in 4 colors (9 of each color)
• 5 paperclips

#19: Leak-Proof Bag

• Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

• Zip-lock bags
• Objects with sharp ends (pencils, bamboo skewers, etc.)

#20: How Do Leaves Breathe?

• Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

• Large bowl (preferably glass)
• Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

• Popsicle sticks
• Rubber bands
• Plastic spoons
• Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

• Clean 16-oz soda bottle
• 6% solution of hydrogen peroxide
• 1 packet of dry yeast
• Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

• Penguin image (included in link)
• Spray bottle
• Blue food coloring (optional)

#24: Rock Weathering Experiment

• Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

• Plastic wrap

#25: Saltwater Density

• Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

• Four clear glasses
• Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

• Toaster oven

#27: Inertia Wagon Experiment

• Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

• Stack of books

#28: Dinosaur Tracks

• Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

• Used coffee grounds
• Wooden spoon
• Rolling pin

#29: Sidewalk Constellations

• Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

• Sidewalk chalk
• Small stones
• Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

• Plastic bottle
• Rubber band

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

• Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

• Clay or gumdrops (in four colors)
• Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

• Straws (paper work best)
• Twine or yarn

#34: Solar Energy Experiment

• Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

• 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

• Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

• Pencil with eraser
• Aluminum tray or pie tin
• Styrofoam tray

#36: Tie-Dyed Milk

• Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

• Shallow dish
• Milk (high-fat works best)

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

• Safety pins
• 2 glass jars

Summary: Cool Science Experiments for Kids

Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child's specific interest or what they're currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

Simple But Fun Elementary Science Experiments to Try in Your Classroom

Written by Holly (Teach Starter)

Looking for some fun elementary science experiments you can do in the classroom that will wow your students? Getting hands-on with science and creating projects that are doable in a classroom setting but also have an element of “cool” are the Teach Starter team’s favorite way to get our students hooked on science.

So we put together some of our very favorite simple science experiments for kids to try out in your classroom! From making an eggshell disappear for a chemistry lesson to showing off the capillary action of flowers for biology, these science experiment ideas will be a sure hit in your classroom!

Simple Elementary Science Experiments

We have developed a series of simple elementary science experiments that are perfect for the busy teacher! Bonus: All of these fun experiments are simple to do and use everyday items.

Science Experiment: Make an Eggshell Disappear

This fun classroom science experiment falls under seriously simple — all you need is some white vinegar, a raw egg, and a glass jar for a chemistry lesson! Your students will learn all about the chemical reaction that occurs when you put an egg into vinegar and leave it overnight. This chemical reaction makes the egg shell disappear but will leave the rubbery membrane, keeping the egg intact.

For a simple description of the chemistry involved, the equipment required, the method and further questioning for your students, download our  Make an Eggshell Disappear – Science Experiment Booklet.

Science Experiment: Make a Rainbow with Water

Everyone loves a rainbow! Students learn all about density in this physics science experiment. They will use different measurements of sugar to create a variety of densities of colored water. Eventually, they will be able to layer water on top of the water, creating a rainbow tower. Sounds like fun, hey?

Again this experiment only requires water, food coloring, sugar, and some different glass jars! To read all about it, download our  Rainbow Water Density Tower – Science Experiment Booklet .

Science Experiment: Capillary Action of Water in Flowers (Biology)

This is always a class favorite! Students learn about how water gets from the bottom of a flower stem all the way to the petals by putting them into colored water!

Download our  Capillary Action of Water in Flowers – Science Experiment Booklet . In our ‘Take it Further’ section of the science booklet, get students to research early botanists.

Science Experiment: Rainbow Bubble Snake

Create a fun, colorful serpent with some simple ingredients for a science experiment that will leave kids giggling!

All you need is:

• Empty plastic bottle
• Dishwashing liquid
• Rubber band
• Food coloring
• A dish of water

• Make the bubble solution by adding water into a shallow dish and adding a few squirts of dishwashing liquid.
• Make the snake by carefully cutting the bottom of the bottle (adults will need to help). Then, place the sock over the end of the bottle and place a rubber band over it to secure it in place
• Wet the sock end with some of the bubble solution, then add a few drops of food coloring on to the end – the more colors, the more colorful!
• Finally, dip the sock end in the bubble solution one more time, and blow through the other end of the bottle. Your rainbow serpent will start to grow…

The hydrogen atoms in one water molecule are attracted to the oxygen atoms in the other water molecules, making the bubbles attach to each other when they come out of the sock fabric. The bubbles are forming because of the air being blown into the soap solution. The air is getting trapped under the surface of the flexible soap skin, stretching it into a sphere shape.

Make it a fair tes t by changing one variable, such as the material or perhaps a different-sized bottle.

Science Experiment: Create a Lava Lamp Science Activity

This simple science experiment for elementary students is an oldie but a goodie!

• Two glasses
• Vegetable oil
• Alka-Seltzer tablets

• First, mix half a cup of water with some drops of food coloring. You can make two different batches with different colors if you wish to make more than one lava lamp.
• Then, fill a glass 3/4 full with vegetable oil. Pour some of the colored mixture into the oil, being careful not to fill the glass too much.
• Add one Alka-seltzer tablet and watch the chemical reaction…

The Alka-seltzer tablets react with the water to produce carbon dioxide gas bubbles! These stick to the water droplets. The water and gas combo is less dense than the oil, so they rise to the top of the glass!

Make this a fair test by changing the amount of Alka-seltzer added. One glass you can add one tablet, another can have two tablets and another can have three. What happens?

Science Experiment: Refraction of Light Science Activity

File this science experiment for kids under SUPER simple. And seriously, we mean super!

• Glass of water

Draw something on a piece of paper. An arrow is a great visual to start this science activity, as it is obvious what happens when you put the glass of water in front of the drawn arrow. But, you don’t have to limit it to arrows. Get creative and draw anything you would like to see through the glass.

When the light is passing through the glass of water, it refracts or bends. The glass of water acts as a cylindrical convex lens and produces an inverted image.

Create a fair test by changing one variable. What happens if you change the size of the glass. Or what if you change the liquid variable? Does it change the result?

Math & ELA | PreK To Grade 5

Kids see fun ., you see real learning outcomes ..

Watch your kids fall in love with math & reading through our scientifically designed curriculum.

Ingredients Required :

A plastic bottle, fizzing tablets, vegetable oil, water, food coloring.

How to Set Up:

• Fill a plastic bottle with water (1/4th part) and vegetable oil (remaining amount). 
• Add food coloring and wait for a few minutes before putting a fizzing tablet in the bottle. 
• Then, turn off the lights and flash a light on a lava lamp to observe colorful blobs building. 

Jar, water, small votive candles, food coloring, matchstick. 

• Pour the colored water into a shallow dish and place a small votive candle in the middle. 
• Lighten the candle and quickly place an empty jar over it. 
• Watch the candle burning slowly. This will eventually raise the water level in the dish. 

Tissue paper, six paper cups, and six different food coloring. 

• Pour water into all six paper cups and add different food colors to each one. 
• Using tissue paper, arrange them in a circle to create a bridge between cups. 
• Wait for a few minutes to complete this kids’ science experiment. Your child will be amazed to see water walking from one cup to another.

An orange and baking soda. 

• Slice an orange into different sections for this simple kid’s science experiment. 
• Then, dip a section into baking soda and ask your students to take a bite. 
• When orange bubbles form in your students’ mouths, they will surely enjoy this experiment. 

A jar, six glasses, sugar, food coloring. 

• Pour water up to an equal level in all six glasses and put different food colors in each glass. 
• Glass 1 – 2 sugar scoops,
• Glass 2 – 4, etc. 
• Once the sugar dissolves in the water, use a water dropper to pour colorful water into an empty jar. 
• Due to different density levels of water, colored water will form separate layers in the jar, making it look like a rainbow. 

A soda bottle, ½ cup hydrogen peroxide liquid, dry yeast, warm water, a small cup, safety goggles, and liquid dish soap. 

• Put on your safety goggles and pour hydrogen peroxide liquid into a bottle. 
• Add food color and liquid dish soap into a bottle. Shake it. 
• In a small cup, mix warm water and yeast for 30 seconds. 
• Finally, let your students pour the yeast mixture into a bottle to form colorful foam. 

Raisins, warm water, vinegar, a cup.

This is a simple kids’ science experiment for young STEM students. Just pour water and vinegar into a transparent cup along with some raisins. The water and vinegar reaction will keep raisins floating and engage your students. 

A jar, saucepan, water, sugar, food coloring, skewer, clothespin, thread. 

• Pour water into a saucepan and place it over the stove. Keep adding sugar into the Water until Water reaches saturation level (no more sugar can dissolve in water). 
• Cool the water down and pour it into a jar along with your favorite food coloring. 
• With the help of a skewer and clothespin, hang a thread in the middle of the jar. 
• It takes time for the crystallization process to start, but gradually dissolved sugar will wrap around the thread to create rock candy. 

A tray, milk, food coloring, toothpick sticks, liquid dish soap.

Magic milk is a fun kids’ science experiment for preschoolers. Just pour milk into a tray and add dollops of different food colors. The color will remain in the milk until kids use toothpick sticks dipped in liquid dish soap to twirl milk as they please. 

Three bread slices, ziplock bags.

This is a quick kid’s science experiment to teach your students the importance of handwashing. Give three bread slices to your students and ask them to put them in different ziplocks. Before that, make them touch one bread slice with regular hands, one with water-washed hands, and another with sanitizer-clean hands. When they see how fast mold grows on the bread they have touched without washing their hands, they will never touch food without cleaning their hands. 

11. Balloon Blowing Trick

Balloons, vinegar, baking soda, a bottle 

• Take a balloon and pour vinegar into it. 
• Put some baking soda in an empty bottle. 
• Attach a balloon over the mouth of a bottle so that vinegar slowly pours inside it. 
• The reaction between vinegar and baking soda will produce gas, blowing up the balloon. 

Ingredients Required: 

Battery, small bulb, wires

How to Set Up:  This electricity experiment helps teach kids about electrical circuits. Connect one end of a wire to the positive terminal of the battery and the other end to the metal base of the bulb. Connect another wire from the negative terminal of the battery to the side of the bulb. Watch as the bulb lights up, showing how electricity flows through a circuit.

13. Leak Proof Bag

A ziplock bag sharpened pencils, and water.

10 Super Simple Science Experiments for Elementary Students

by Sara Ipatenco

Science is one of the core subjects necessary in every elementary school classroom. Experiments are a critical part of any science curriculum, because they allow your students to get up close and personal with learning concepts. Science experiments don’t have to be expensive, hard, or time-consuming. With a few inexpensive materials, a science lab, and a class period or two, you can bring science alive for your students. Here are 10 experiments to get your students started.

Just so you know, we may get a small share of the sales made through affiliate links on this page.

1. Dancing popcorn

Materials needed:.

• 1-quart jar
• 1 tablespoon popcorn kernels
• 2-4 tablespoons baking soda
• 1 cup white vinegar

Directions:

• Fill the 1-quart jar about three-quarters with water.

2. Add the baking soda to the water and stir until it’s dissolved.

3. Gently pour the popcorn kernels into the jar.

4. Slowly pour in the vinegar. Go slowly or you’ll get a volcano overflowing over the top of the jar.

5. Watch the popcorn kernels dance! The reaction between the baking soda and vinegar causes bubbles to form in the liquid. As the bubbles move, they knock into the popcorn kernels, causing them to look like they are dancing.

2. Lemon volcano

• Food coloring
• Baking soda
• Cut the lemon in half. Slice a tiny sliver off the bottom of one lemon half so it sits flat on a plate. Cut a few slits in the flesh of the lemon.

2. Place a few drops of food coloring on the lemon half sitting flat on the plate. Use two or three colors for a more colorful reaction.

3. Squeeze a bit of dish soap on the lemon half right on top of the food coloring.

4. Sprinkle a spoonful of baking soda on top of the dish soap. Use the back of the spoon to press the baking soda into the flesh of the lemon.

5. Squeeze the other half of the lemon on top of the baking soda. You should start to see a colorful reaction right away!

6. Keep squeezing until you’ve gotten all the juice out of the second lemon half. As the lemon juice reacts to the baking soda it will fizz. The dish soap will also bubble, mixing with the food coloring to make the experiment colorful and easy to see. It works because of the reaction of the acidic lemon juice with the baking soda and dish soap.

3. Turning pennies green

• Paper towels
• White vinegar
• Pennies dated 1981 or older – younger pennies don’t have enough copper to get the proper reaction necessary to make this experiment work
• Place a folded paper towel into the bottom of a bowl.

2. Place the pennies on top of the paper towel. Put some of the pennies heads up and some of the pennies tails up so your students can see the green in a couple different ways.

3. Pour enough white vinegar over the pennies to saturate the paper towel. Save the rest of the vinegar to refresh the paper towel as it dries.

4. Observe the pennies after an hour or two. The green will just be starting to appear on the pennies.

5. Leave the pennies overnight. Observe them again the next day. There will plenty of green appearing on the pennies. The green, which is called malachite, continues to appear because of the chemical reaction between the copper, the vinegar, and the oxygen in the air. This is why the Statue of Liberty is green!

4. Glitter Germs

• White plate
• Fill the plate with water. Sprinkle glitter over the surface of the water. The more glitter you sprinkle, the more dramatic the reaction will be.

2. Have your students dip one finger in dish soap.

3. Students will gently dip their soap-covered finger into the center of the plate.

4. Observe what the glitter does! It will immediately scatter away from the soap. This happens because the soap lowers the surface tension of the water, which causes the molecules to scatter – the glitter just makes it so your students can see that happen. This is a great science experiment to teach the importance of washing hands – the soap will literally make the germs scatter!

5. Exploding baggies

• Plastic zip-top bag
• One square of toilet paper
• Pour half a cup of vinegar into a plastic zip-top bag.

2. Place a spoonful of baking soda into a square of toilet paper.

3. Fold the toilet paper square up to make a small packet.

4. Head outside because the next part will get messy! Once outside, quickly place the toilet paper packet in the bag, squeeze the air out, zip the bag closed, and set on the sidewalk. It’s important to do this part quickly!

5. Back up and watch. The bag will start to puff up.

6. Keep watching!

7. Watch some more. It’s almost there!

8. Bang! The bag will explode! This experiment works because the vinegar and baking soda create carbon dioxide gas in the bag. As more carbon dioxide is made, it builds up in the bag until the bag can’t hold any more. That’s when the bag pops.

6. Walking water

• 6 small glass jars
• Red, yellow, and blue food coloring
• Place the 6 glass jars in a circle so the jars are touching each other. Fill every other jar about three-quarters full of water.

2. Place a few drops of red food coloring in one jar, skip the empty jar, add yellow food coloring to the next jar, skip the empty jar, and then add blue food coloring to the next jar.

3. Fold six paper towels into fourths the long way.

4. Place the end of one paper towel in the red jar and the other end in the empty jar. Then place the end of another paper towel into the same empty jar and the other end in the yellow jar. Take the third paper towel and place one end in the yellow jar and the other end in the next empty jar. The fourth paper towel will have one end in the empty jar and the other end in the blue jar. The fifth will have one end in the blue jar and the other end in the following empty jar. The last paper towel will have one end in the empty jar and one end in the red jar.

5. Watch the paper towels begin to absorb the colored water.

6. After a few minutes, the paper towels will be saturated with the primary colors.

7. Keep watching and the colors will begin to transfer from the jars you filled to the empty jars. The experiment works because the primary colors will mix in the empty jars making the secondary colors. The paper towels will then begin to absorb the secondary colors, making it look like the water is walking from jar to jar.

• 4 cups white vinegar
• 4 tablespoons baking soda
• Large cooking pot
• Glass measuring cup
• Pour 4 cups of white vinegar into your cooking pot.

2. Add baking soda, one tablespoon at a time, to the white vinegar.

3. Stir the mixture well after each tablespoon. This will prevent the pot from overflowing.

4. Boil the white vinegar and baking soda mixture on medium-low heat for about an hour. You want to boil it long enough that that much of the liquid is boiled out. You want about three-quarters of a cup of liquid.

5. Scrape a small amount of the dried powder from the side of the pot and place it in the middle of a colored plate. A colored plate isn’t required, but it will make it easier to see the hot ice grow.

6. Pour the liquid into a glass measuring cup. It will be quite hot, so this is a job for the teacher! The liquid might also have a yellow tinge to it. This is normal and will not change the outcome of the project. Begin slowly pouring the liquid onto the powder on the plate. Patience is the key from here on out. Your students will need to pour the liquid very slowly or it will just spread all over the plate rather than growing.

7. Keep pouring, a drop or so at a time, and watch the ice begin to grow.

8. Keep pouring until you’ve used up all the liquid. The “ice” will continue to be hot to the touch, so make sure your students aren’t touching the ice as it grows. It works because the powder “seed,” called sodium acetate, crystalizes and releases heat energy, which is why it will be hot to the touch. It’s the same process used to make hand warmers.

8. Floating ink

    materials needed:.

•     White glass plate
•     Dry erase markers

    Directions:

• Draw simple pictures on a white glass plate using the dry erase markers.

2. Use another color to draw a few more images on the plate.

3. Place a small amount of water into a glass jar. Carefully pour the water onto the edge of the plate.

4. Watch the dry erase images begin to lift off the plate and float on top of the water. It works because the ink in dry erase markers is insoluble, which means it won’t dissolve in liquid. Instead, when the ink in a dry erase marker meets water, it floats to the top. Have your students experiment with different colors of dry erase markers and different temperatures of water to see if that changes the how quickly and easily the images float.

9. Snowstorm in a jar

• A glass jar
• White paint
• Blue food coloring
• Alka-seltzer tablet
• Fill a jar about three-quarters full of baby oil.

2. In the small bowl, mix white craft paint with water until the paint is completely stirred into the water.

3. Add several squirts of blue food coloring and a generous amount of glitter to the baby oil. Slowly pour in the white paint and water mixture.

5. Carefully drop an Alka-seltzer tab in the jar.

6. The snowstorm will immediately start in the jar! Your students will begin to see the glitter, blue oil, and white paint start to swirl slowly in the jar.

7. Keep watching because the snowstorm will get crazier! It works because water is denser than oil so the white paint water will sink to the bottom of the jar. The Alka-seltzer causes a chemical reaction with the water, forcing the water up toward the top of the jar. At the same time, the oil will be blocking the water, forcing it back down toward the bottom of the jar. These opposite forces of pressure make it look like there’s a blizzard!

10. Crushing cans

• Empty aluminum can
• Small cooking pot
• Fill the empty aluminum can with just enough water to cover the bottom and place it in a small cooking pot and over medium heat.

2. While you are waiting for the water in the can to boil, fill a bowl with plenty of ice and water.

3. Keep an eye on the can. Peek in the top to see if the water has started to boil.

4. Once the water is boiling, the teacher will use the tongs to remove the can from the pot.

5. Immediately turn the can upside down into the bowl of ice water. The can will crush instantly. It works because the steam from the boiling water in the can pushes all the air out the opening at the top. When the can is placed in the ice water, the steam cools and water takes it place. Since water takes up less space than steam, the blocked opening of the can makes it impossible for air to fill up the space the steam previously took up. The result is instant crushing.

With a few simple ingredients and class period or two, your students will learn a ton about scientific concepts while also observing just how much fun science can be.

16 easy science experiments for kids in the classroom.

Why are science experiments important? Kids are naturally inquisitive and love learning new things.

What better way to satisfy their curiosity than through science! Not only will the kids be having fun conducting these experiments but they will be learning too.

This guide will share 16 cool kids’ science experiments . They range from experiments involving diet coke and mentos to more elaborate experiments that create mummified apples.

List of 16 Science Experiments 

1. coke and mentos experiment for kids.

This is a reaction between Mentos candy and cola. The experiment involves dropping several Mentos candies (usually 5–8) into a bottle of diet cola resulting in an eruption occurring because of rapidly expanding carbon dioxide bubbles on the surface of the Mentos.

If you want an explanation:

There are various theories being debated as to the exact scientific explanation of the phenomenon, many scientists claim that it is a physical reaction and not a chemical one.

Water molecules strongly attract each other, linking together to form a tight connection around each bubble of carbon dioxide gas in the soda.

To form a new bubble, water molecules must push away from one another. It takes extra energy to break this surface tension. So, in other words, water resists the expansion of bubbles in the soda.

When Mentos are dropped into soda , the gellan gum and gum arabic of the candy dissolves and breaks the surface tension. This disturbs the water connection so that it takes less work to expand and form new bubbles.

Each Mentos candy has thousands of tiny pores over its surface. These tiny pores function as nucleation sites, perfect places for carbon dioxide bubbles to form. As soon as the Mentos enter the soda, bubbles form all over their surface.

They quickly sink to the bottom, causing carbon dioxide to be released by the carbonated liquid with which they come into contact along the way. The sudden increase in pressure pushes all of the liquid up and out of the bottle.

2. Alka-seltzer rocket experiment

A model rocket fashioned from a 35mm film canister and propelled by the generation of gas from an effervescent liquid. It is often used in science classes to demonstrate principles of chemistry and physics to students.

1. In the experiment, a film canister is filled with water and an effervescent tablet (commonly Alka-Seltzer) and tightly sealed.

2. After a short time, the evolved carbon dioxide reaches sufficient pressure to cause the body of the canister to be launched into the air with a popping sound.

3.  The canister may be elaborated with paper fins to resemble more closely as a real rocket.

(K-A tested) more simple rocket launch. Fill a small plastic film canister (Fuji works well) with one teaspoon of water. Quickly add one Alka-Seltzer tablet, put the lid on and place the canister on the floor with the lid side down. Wait about 10 seconds and whoosh! Your rocket should fly into the air .

3. Building a macaroni skeleton

Directions:

• Build a sample skeleton for the children to copy from. Review the key features with them.
• Guide children to build their skeleton working from the head down (i.e., head, neck/trunk, ribs, etc.), gluing the macaroni and beans to the paper as they go.
• When the glue and macaroni have set, have them draw a smile and eyes on the “head”.

Tip – As preparation for this project, study the human skeleton. Talk about symmetry between the two sides of the body, and how many ribs, fingers, and toes we have.

4. Egg drop science experiment

(K-A tested-the grade school and middle school kids loved it!)

Each student works within guidelines to fashion a container for an egg so that the egg won’t break when the student drops it from an established height.

Use hard-boiled eggs (you could probably do raw-but be cautious of Salmonella and spoilage!).

Have each child create their own container for the egg – with the purpose of the egg not breaking. Some kids have used “parachutes,” and cans with foam. It can be a lot of fun!

Of course, everyone’s hypothesis should be that their egg won’t break.

The testing is the fun part when the kids see if their egg remains intact. For this, you want to drop the egg container from the highest available point. A second-floor balcony, off the top bleacher of the football field or by a teacher on a ladder?

*Even though this is for older students, it can be adapted to the lower grades without going into weight and velocity.

5. Invisible ink science experiment

• 2 tablespoons of pure lemon juice
• Cotton swabs
• Pour the lemon juice into a small dish.
• Soak the end of a cotton swab in the lemon juice and use it to write a secret message or a picture.
• To read or see your secret message, hold the paper near a warm light bulb, burner, or toaster.
• The heat will turn the invisible writing brown and you can see it!

6. Spin experiment for kids (how long can you spin?)

• Film canister lid
• Construction paper
• Bamboo skewer
• Cut a circle out of construction paper, about the size of a DVD or CD.
• Tape a film canister lid to the center of the paper circle. (You can draw a design on it-that would look interesting spinning)
• With an adult – poke or drill a hole through the film canister lid.
• Poke the skewer through the hole in the lid.
• Keep the paper circle near the point of the skewer. Give the skewer a twirl.

How does it work

The paper circle gives the skewer extra mass. When you twirl the skewer, you also twirl all the mass of the paper circle. A spinning mass tends to keep spinning unless something like friction slows it down.

About 72% of kids can make it spin more than 10 seconds

7. Center of gravity experiment

Even George Washington couldn’t do this dollar pick-up trick! Tell the children you’ll give them each a dollar if they can pick it up from the floor. But there is a catch: They have to pick it up using your instructions. You’ll have fun fooling them with this easy indoor game for kids.

You’ll need a dollar bill and a wall

Step 1: Have children stand with their feet together and heels up against a wall.

Step 2: Put dollar bills on the floor 12 inches in front of their feet.

Step 3: Tell them to pick up the dollars without bending their knees or moving their feet.

It is impossible to do! Why? When you are standing against a wall, your center of gravity is over your feet. If you bend forward, you have to move your center of gravity forward to keep your balance. Since you can’t move your feet during this trick, you’re flat out of luck. But that’s better than being flat on your face.

8. Ringing ears – Simple sound experiment for kids

• 3 feet of String/Thread
• Take the string and tie the fork to the center of the string/thread.
• Take one end of the string/thread and tie it around your right index finger (pointer), then tie the other end of the string/thread around your left index (pointer) finger.
• Place your fingers (index/pointer) to your ears and let the fork dangle in front of you.
• Get someone to tap the fork with the spoon. You should hear loud ringing in your ears.

The ringing sound travels up the string/thread to your ears.

You could tie other metal objects to the string/thread to see what sounds travel to your ears.

9. Mummification science experiment

Discover how the Ancient Egyptians used drying as one step

#1 Experiment: fish mummy

• l raw fish from the market
• Two boxes of baking soda
• Kitchen scale
• Plastic container with a lid

Instructions:

• Weigh the fish on a kitchen scale.
• Coat the fish inside and out with baking soda, and bury it completely in baking soda in the plastic container. Let it sit this way for a week in a cool shady place (in a refrigerator, if you like).
• After a week, take it out, dust it off, and weigh it again. Re-bury it in fresh baking soda, for another whole week.
• Take it out and weigh it once more.

What does the fish look, feel, and smell like?

Baking soda acts as a preservative and drying agent. The weight loss you noticed is due to the removal of water by the baking soda. Drying the fish is essential to making it a mummy. What happened after the first week? After the second week?

10. Sink or float – water buoyancy experiments

Can you sink an orange?

What you need?

✓ A Bowl ✓ Water ✓ 1 Orange

How to do it:

• Fill the bowl with water.
• Put in the orange…What happens to the orange?  See if you can get the orange to sink.
• Take the orange and peel it.
• Place the peeled orange back in the bowl of water. What happens this time?
• The orange sinks because the orange peel if full of trapped air pockets, therefore making the orange light for its size (so   it floats).
• When you remove the peel (including the air pockets) the orange weighs a lot for it.

Along with the above experiment try a ‘Sink or Float with a Pumpkin or Watermelon.

• Fill a bin or aquarium or tub half full of water. Place everyday items near the bin. Get the kids to guess which items would sink and which ones would float. Have youth write their guesses in their notebooks. Then do the experiments to determine if they were right or not.
• Be sure to add watermelon to the guess! (You can eat it afterward!) Pumpkins are also fun. The pumpkin and watermelon will float because its mass is less than the mass of water it displaces. This is due primarily because the inside of the pumpkin and melon are hollow. It is mostly air, which has a much lower mass than water.

11. Crystal growing experiment

• Epsom salt, a tablespoon
• A cup of water
• A paper circle
• Cut out a paper circle the same size as the jar lid. Put the circle in the lid.
• Measure 4 big tablespoons of Epsom salt. Don’t worry if you add too much – the more, the better.
• Dissolve all 4 tablespoons in the water and stir the mixture thoroughly.
• Pour the water mixture into the jar lid. Stick the lid in a place where it won’t be disturbed. It will take a few days, but let the water evaporate and see what happens.

In a few days, the water will evaporate from the lid. But the Epsom salt will be left behind. The salt will build up into its own unique crystal shape. You can make a miniature rock forest.

This is a classic science experiment and an easy one. To make the volcano, mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The mixture should be smooth and firm.

Stand a large soda bottle in a baking pan or shallow dish, and begin to shape the dough around it. Don’t cover the hole and don’t drop any of the dough into it. Fill the bottle about three-quarters full with warm water and a few drops of red food coloring. Add 6 drops of liquid detergent to the bottle, and 2 tablespoons of baking soda.

Slowly pour vinegar into the bottle and step back.

13. Dancing popcorn

Fill a clear cup  3/4 full with vinegar. Add 1/2 teaspoon baking soda. Drop-in a few kernels of unpopped popcorn. Watch as the kernels rise and fall.

Variations: Try substituting club soda for the vinegar and baking soda. You can also try using other objects like buttons or pebbles.

14. Bread mold experiment

This is a very easy science experiment. The most difficult part is the patience to see the experiment through.

Children seem to love watching mold grow. Here is a safe way to experiment with mold.

• Give children a small zip-lock bag and a piece of bread.
• Have them place the bread into the bag and then add a teaspoon of water. Zip up the bag and set out the bag to observe.
• After a few days, mold will appear on the bread.
• Discard bags unopened, when the experiment is over.
• Variation: You may want to repeat this experiment, but this time make two bags of water and bread and put one in the center and one in the refrigerator. Which one grows mold the fastest?

15. Fingerprint lift experiment

Here’s an amazing trick that lets children try their hands at a little forensic science by lifting their own fingerprints.

1. Individually, have each child press their fingertip on a pocket mirror.

2. Cover the entire print with graphite dust by rubbing a soft pencil with sandpaper.

3. Blow gently to remove excess dust.

4. Now carefully stick a strip of tape to the print and slowly peel it off. Stick the tape to a piece of white paper, and the print should be distinct. You can inspect the fingerprint under a magnifying glass, or just with the eye.  If you go to the wiki website, I you can decide whether the fingerprints are ‘s’ whirl, loop, or an arch.

16. Make a ‘naked egg’ – Egg in vinegar experiment

A naked egg is an egg without a shell. Using vinegar, you can dissolve the eggshell without breaking the membrane that contains the egg.

• White vinegar
• A container big enough to hold all the eggs
• A cover for the container
• A big spoon
• Place eggs in the container so that they are not touching.
• Add enough vinegar to cover the eggs. Notice that bubbles form on the eggs. Cover the container and put it in the refrigerator. Let the eggs sit in the vinegar for 24 hours.
• Using the spoon, scoop the eggs out of the vinegar. Be careful the eggshell has been dissolving. The egg membrane, which is not as durable as the shell, maybe the only thing holding the egg together.
• Carefully dump out the vinegar. Put the eggs back in the container and cover them with fresh vinegar. Leave the eggs in the refrigerator for another 24 hours.
• Scoop the eggs out again and rinse them carefully. Throw out the eggs where the membranes have broken and are oozing out.
• When complete, there will be an egg without a shell. It looks like an egg but is translucent. The membrane will flex when squeezed.

Explanation :

An eggs shell dissolves when submerged in vinegar.

Vinegar contains acetic acid, which breaks apart the solid calcium carbonate crystals that make up the eggshell into their calcium and carbonate parts.

The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide.(Those are the bubbles that you see)

Note: The shell dissolved in 24 hours. Although directions say to put the egg in the refrigerator, I forgot to. (It still came out fine) The remainder of the experiment was followed as directed. After a couple of days, you could actually see the yolk floating within the membrane. Both kids and adults liked this one! The egg feels rubbery but it does ‘splat’ when dropped.

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.

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.

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.

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.

Dollar Store Science: 10 Easy Experiments You Can Try Right Now

Stretch that science budget!

Teaching science requires a lot of hands-on activities to help students connect to concepts in a experiential way. Take a peek into any science equipment catalog and you can find amazing ways to accomplish this. But the reality is that many elementary classrooms don’t have school budget money to outfit a science lab with the latest cool gizmos and gadgets. Here are some inexpensive science experiments that teach important concepts without breaking the bank.

1. Navigate Newton’s Laws of Force and Motion.

Head to the toy aisle and snap up some cars and a bag of marbles. Then swing by the party aisle for some straws and a package of balloons. Also, make sure you grab a package of bathroom cups and you are ready for three great activities that can be used in an 3rd–6th grade classroom to introduce or extend learning about Newton’s laws of motion.

Newton’s first law can be tackled by making a ramp out of an old game board (Finally! A use for that Candyland game you found at a garage sale last year!). Place a book at the bottom of the ramp to act as the force stopping the car you will place at the top of the ramp. Place a penny on the hood or roof of the car and let the car roll down the ramp. Measure how far the penny continues to travel after the car has stopped. You can change the angle of the ramp and determine if it has any effect on the distance the penny will fly.

For a great activity to demonstrate Newton’s second law, use a book and a ruler to make a ramp. Cut an opening in the side of a bathroom cup and place it at the bottom of the ramp. Roll the two different sizes of marbles down the ramp and measure how far they push the cup.

If you need help teaching Newton’s third law, use the balloons and straws to make rockets. Start by threading a straw onto a length of string or fishing line. Stretch the string across your room and attach each end to a wall. Blow up a balloon and twist the end closed, but don’t tie it. Tape the balloon to the straw and let go. The force of the air pushing out of the balloon will send it zipping down the string.

2. Take a spin to learn about friction.

Friction can be a tricky topic for kids because the only example they can usually come up with is rubbing their hands together. Here are a couple of activities that can help build their understanding of opposing forces and only cost a couple of dollars.

Haul out those old game boards again and cover them with whatever different textures you can find. I use foil, shelf liner, bubble wrap, cardboard, wrapping paper, and a welcome mat. Make a ramp out of heavy paper or cardboard. Prop one end of the ramp on whatever is handy and roll a toy car down it. Measure the distance the car travels on each of the different surfaces.

Grab packages of tops from the party favor section of the store. Have the students choose several surfaces that have different textures like the top of their desk, carpet, tile. Have the students time how long the top will spin on different textured surfaces. You can even head outside and try asphalt, grass, and concrete.

3. Model the phases of the moon.

You can make an inexpensive model that demonstrates the phases of the moon out of ping pong balls and bottle caps. Use an orange or yellow ball to represent the sun. Use a permanent marker to color half of a white ping pong ball black. This will represent the moon. I found some cute doggie balls that were blue and green and use them to represent Earth. Students can see what the moon looks like as it makes a trip around the Earth.

You can also pick up a hula hoop and attach eight moons evenly spaced to it. Students can take turns standing in the hoop while their friends hold it at eye level. By turning in a full circle, the student in the center can see all of the phases.

4. Chase shadows to track the sun’s motion across the sky.

Many students struggle with understanding why the sun changes position and how we see that change. A simple and fun way to help students track the position of the sun during different parts of the day is to trace their shadow using sidewalk chalk. Have the student who is being traced stand in the same exact location several times during a sunny day. Use a different color of chalk each time to trace their shadow. At the end of the day you can have a discussion about the direction their shadow is, the changing length of their shadow and how this relates to the location of the sun during different times of the day.

5. Bounce around to learn about energy.

Dollar stores are a great place to find a variety of balls: foam, rubber, bouncy, hard, soft, squishy, knobby. Pick up several different kinds and have the students design an experiment to test which kind of ball bounces the highest or the most times when dropped from a certain height.

6. Sort all sorts of doo-dads to learn about classification.

Do your students need help understanding classification? Are they ready to try making a dichotomous key on their own? There are plenty of inexpensive choices to be found at any dollar store. Craft supplies like pompoms, foam stickers, bags of buttons, beads of every shape, size and color make a perfect, kid friendly classification starting point.

7. Witness the dance of solar energy.

Look at your local Dollar Store for items that have a solar panel. You can incorporate these items to help kids understand concepts such as light as a form of energy and that light energy can be changed into other forms of energy by solar panels. I found a whole shelf of dancing flowers as well as solar powered calculators.

8. Light up learning around circuits.

Instead of spending lots of money on battery holders, bulb holders, bulbs, and wires with special clips, I headed to the dollar store and picked up a string of Christmas tree lights, a box of foil, and some electrical tape. Add a 9V battery and you have everything you need to make a circuit. Tape a strip of foil to each post on the battery, making sure the the two pieces of foil don’t touch. Then clip every other bulb from the strand and strip about a half inch of the insulation off of the wire and you are ready to create a circuit. Students can even place objects between one wire and the foil to determine if the object is a conductor or insulator.

9. Model your own cave formation.

If your students need to understand how solution caves form, here’s a terrific model they can make using clear plastic cups, modeling clay, and sugar cubes. Place a dozen or so sugar cubes in the bottom of a clear plastic cup. These represent limestone. Top that off with a thin layer of modeling clay to represent the surface. Slowly pour water into the cup. The water will begin to seep through cracks around the edge of the cup and as it collects in the bottom, the sugar cubes will begin to partially dissolve leaving open spaces. Have the students sketch the changes.

10. Use play dough to learn about fossils and the layers of the Earth.

Everybody loves Play Dough. Dollar Stores usually have inexpensive versions. They also usually have tubs or tubes of dinosaur figures. If you can’t find any with the toys, check the party supplies where they may be packaged as a party favor.

Students can roll out different colors of the dough and stack them up to represent the layers of sedimentary rock. You can use their models to discuss which layer is oldest. Provide students with a plastic knife or craft stick and they can make models of movement along fault lines or they could use a plastic spoon to model canyon formation. If you include a dinosaur between two layers, the students can make a model of a cast and mold fossil.

This activity could be extended by burying dinosaurs in plastic bowls full of sand. Stack three bowls inside each other to represent three layers of sedimentary rock. Give your amateur paleontologists a toothbrush and allow them to “dig” up their fossils and determine which one is the oldest and which is the youngest.
