Messiness factor: 1 sponge 

Cup Amplifier

cool science experiments to try

A lesson in: Sound

Slide a mobile phone into this low-tech amplifier and the result will be music to your ears. The audio is deeper, richer, and louder, thanks to the science of sound waves and the natural amplification created by the cone-shaped cups. If the two cups look a bit like the attentive ears of a cat or fox, that’s no coincidence. Animal ears use the same science, but in reverse: they help creatures hear by gathering sound waves and directing them into the ear. For engineers, that’s a design worth copying.

Customize your amplifier to fit any size phone!

Tabs cut all around the hold make it easy to glue the cardboard tube in place.

Cut a slot with a flap to support your phone.

What’s Going On The Cup Amplifier focuses and projects sound waves, in the same way that a cheerleader’s megaphone (or even just your cupped hands) amplifies your voice. Once sound waves are created, they want to spread out in all directions. The amplifier directs them from your phone’s speakers into the cardboard cups, where, instead of scattering, they are gathered and channeled in one direction—out the openings.

A Lesson in: Chemistry

An easy science experiment to do at home is one that helps kids find out what affects the surface tension of water! You'll need basic materials like a penny and a water dropper, and be sure to make a hypothesis before you start. You might be surprised! Get the tutorial from Rookie Parenting . 

Pulley Experiment

a rope pulley is an easy science experiment

A Lesson in: Physics

This simple experiment requires a trip to the hardware store, but putting it all together is a cinch. Once you've completed the system, have your kids pick up different-sized rocks and make a note about how difficult it is. Then, try with the pulley. Is it easier or is it harder? To find out how to make your pulley, and for other questions to ask your kids, head over to Little Bins for Little Hands . 

Make a Volcano Explode

two boys doing a volcano explosion, an easy science experiment for kids

A Lesson in: Chemical reactions

There's a reason why this science experiment is so popular. When the solid baking soda (sodium bicarbonate—a base) mixes with the liquid vinegar (acetic acid—a weak acid), it creates a gas—carbon dioxide! Besides the chemical reaction, kids enjoy making the actual volcano, whether it's out of clay, mud, or foam sheets. Get a great step-by-step tutorial from The Dad’s Book of Awesome Science Experiments by clicking here . 

Messiness Factor: Four sponges

Bake Hygroscopic Cookies

Hygroscopic Cookies are an easy science experiments to do at home

A Lesson in: Hygroscopy. 

This simple science experiment is best when you check in on it the next morning. Bake up a batch of cookies, then place them in an airtight container with a piece of fresh bread. Watch as the cookies stay straight-from-the-oven soft thanks to the moisture of the bread (The sugar in the cookies is hygroscopic, which means it absorbs water molecules out of the bread). The best part? Getting to eat the cookies!

The Juice-Tasting Challenge

different juices

A lesson in : Taste buds and olfactory senses.

Tummy’s rumbling–it’s time to eat! Did you know that you “eat” with your nose and eyes as well as your mouth? It’s true. Put your family’s sense of smell and sight to the test with this juice-guessing game.

You’ll Need: Masking tape 4 glasses Pen and paper 4 flavors of juice 4 food colorings

How to: 1. Stack a piece of tape on the bottom of each glass and number them one to four, making sure your partner can’t see the numbers. Pour one type of juice into each glass.

2. Send your partner out of the room. Drip a different food coloring into each juice and stir so your partner can’t recognize the juice by its color alone. Record the number, juice type, and color in each glass on a piece of paper.

3. Call your partner back. Tell her to hold her nose, sip from each glass, and guess the juice If she’s like most people, she’ll be kind of confused–her eyes and tongue give her two conflicting flavor messages.

4. Ask her to unplug her nose, close her eyes, and sniff the juice before drinking it. Her guesses should be on target now. All hail the mighty schnoz!

Messiness Factor : One sponge

Dry Ice Bubbles

dry ice bubbles are an at-home science project for kids

A lesson in: Gas.

Dry ice is already cool enough on its own, but it takes science to turn them into bubbles. When you add water, it changes the temperature of the dry ice, causing the ice to go from solid to gas. That’s where the fog and bubbles come from! Head to Simply Modern Mom to get the full tutorial. But be careful: Dry ice can cause serious skin burns, so make sure your kids are well-supervised and know not to touch the ice.

Messiness factor: Three sponges.

Invisible Licorice

cool science experiments to try

A lesson in : Light and perspective.

Did the candy melt or disappear? Your sweetums might think it’s magic, but it’s really all about how oil redirects light, causing half the candy to disappear! Click here for the instructions on how to recreate this mind-warping experiment.

Egg in a Bottle

egg in a bottle is a fun science experiment you can do at home

Your whistler has the basics of air pressure down just by using their mouth to blow. And now you can amaze them with this science experiment for kids. There is a little fire play involved (dropping a lit paper into the bottle), but that’s what causes the unbalanced air pressure, which pushes the egg into the bottle. Want to test it out? Head over to Steve Spangler Science for the tutorial.

Invisible Ink

invisible ink using lemon is a fun science experiment for kids

A lesson in: Oxidation.

If your snacker has noticed how their apples have turned brown after being left out for too long, then they’ve seen oxidization in action (loss of electrons and nutrients when in contact with oxygen). Fortunately, lemon juice only oxidizes when in contact with heat. This method works with baking soda and milk too. Click here to find out how to write secret messages with your little spy.

Kid-Safe Lava Lamps

cool science experiments to try

A lesson in: Density and intermolecular polarity.

These sound like big words for our little ones, but there’s an easier way to break it down. Water and oil won’t mix because they’re not the same “weight” or substance (just like clay and LEGOs won’t become one). Now add a drop of food coloring (which is heavier than oil) and a fizzy tablet and watch the air bubbles take coloring with them to the top. Head on over to S. L. Smith’s blog to see how it’s done .

Messiness factor: Two sponges.

A Lesson in: Crystallization.

Be careful: The water only has the power to make the sugar crystals “invisible” when it’s piping hot. After the water cools down and evaporates, the sugar turns back into a solid. And with a little help of your sugar-soaked string, the crystals will find a home to grow upon and become rock candy. Learn how to make your smart sweets with these instructions from the Exploratorium .  

S'more Solar Oven

cool science experiments to try

A lesson in: Solar power.

Harness the power of the sun to make your favorite campfire treat! With just a few common household items you can create an  eco-friendly oven  just for melting marshmallows and chocolate, plus you can teach kids about the power of the sun. Click  here  to learn how.

Homemade Slime

girls making slime, which is a fun science experiment for kids

A lesson in: Polymers.

Is it a liquid or solid? The answer is both! This DIY slime—made from glue, borax, and water—is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Check out Explorable’s recipe for mixing the ingredients . Prolong the life of your goo by keeping it in an airtight container in the fridge. And, if you need help with cleanup, check out our guide for how to get slime out of clothes, couches, and hair . 

Make Fizzy Lemonade

cool science experiments to try

Plain old fresh-squeezed lemonade is so last year. Boost the fun quotient and learn a simple science concept simultaneously when you recreate this edible Fizzy Lemonade drink from  Learn With Play at Home . It’s super easy to mix and little sippers report it’s pretty tickly too. A great alternative to the baking soda-vinegar volcano, it shows kids what happens when an acid and base are mixed together. 

Whirlpool in a Bottle

cool science experiments to try

A lesson in: physics, weather science. 

This easy little experiment doesn't take much: just two empty and clear 2-liter bottles, a metal washer, water and duct tape. Food coloring is optional. Fill one bottle with about two-thirds water. Place the washer on the bottle and line up the empty bottle on top of the water-filled one. Wrap the duct tape around the middle securing the two bottles together. Then, turn the bottles upside down. Does the water go straight down or do you see a mini whirlpool (Swirl the top or bottom a bit for a better effect.)? The spinning water is called a vortex, and all tornadoes, hurricanes and typhoons are examples of air vortexes. Since you’re using water, this is an example of a whirlpool. As the water spins faster, it pushes to the outside of the bottle creating a hole in the middle. The air from the bottom of the bottle comes up the middle and the water from the top flows back down through the hole.

Messiness factor : Two sponges.

Salt Crystal Feathers

cool science experiments to try

A lesson in: Evaporation

You’ve probably tried a salt crystal growing kit at some point in your life (5th grade Science Fair perhaps?) but Schooling a Monkey takes the idea to a new level with these Salt Crystal Feathers. This awe-inspiring project is deceptively simple and inexpensive to achieve, and requires just a wee bit of patience to see the results—kids will love checking in on the progress. 

Soda Blasting Experiment

soda bottles used in science experiments

A lesson in: Chemistry, pressure, and release of pressure

This experiment is one you'll definitely want to do outside. Step it up with this Mentos + soda experiment: head to Steve Spangler  for all the need-to-know details on this engaging experiment. 

Messiness factor: Three (very epic) sponges

Melting Rates

outdoor science projects for kids

A lesson in: Solar science and absorption

Different colors have different heat-absorbing capacities. Black has the greatest heat-absorbing capacity, which results in ice melting quicker than white, which reflects the most light. Learn how to observe and report on which colors affect ice’s melting rates here on Curiodyssey.  Get more sidewalk science ideas here .

Get the building instructions over at The Science Kiddo .

Disappearing Egg Shell

cool science experiments to try

Can you and the kiddos solve the mysterious case of the disappearing eggshell? Following the simple how-to at Go Science Kids , you’ll learn the step-by-step and talking points about the process along the way. Warning! Although it’s totally non-toxic, toddler-aged kids will be tempted to squeeze the egg at the end so make sure it’s a supervised experiment. Visit Go Science Kids to get cracking!

Fishing for Ice

ice salt is a fun science experiment for kids

A lesson in: Freezing/temperature.

Children living in snow-covered cities might witness their neighbors salting the driveway. Well, while that is definitely not for fun, this experiment is. Salt lowers the freezing point of ice so it melts, but it won’t be able to freeze unless it’s cold enough. See how The Science Kiddo made a clever game with this knowledge.

cool science experiments to try

A lesson in: How clouds hold water.

Let your imagineers pretend shaving cream is a cloud that holds colorful raindrops. As they squeeze more and more food coloring, their “cloud” will soon release the excess below—just like how real clouds get too heavy and let the rain loose on a gloomy day. Learn how to re-create this weather experiment here .

Dyed Plants

cool science experiments to try

A lesson in: Capillary action.

Find out how plants “drink” water with some food coloring . Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments  over  here .

Dancing Oobleck

cool science experiments to try

A lesson in: Sound waves.

The word “oobleck” comes from a Dr. Seuss story where a young boy must rescue his kingdom from a sticky substance. But the neat part of this experiment is how oobleck reacts to vibrations. Put the oobleck over a subwoofer (on top of a cookie sheet!) and watch it dance to different frequencies. Your dancer will see how sound isn’t just about volume! Check out more of this awesome experiment from Tammy of Housing a Forest .

Messiness factor: Five sponges.

Homemade Lightning

cool science experiments to try

A lesson in: Static electricity. (Or weather science.)

Lightning is essentially electrons moving uber fast between the sky and the earth—and with a few simple materials, you can use homemade static electricity (the reason behind your hair sticking up when you rub a balloon or go through a tunnel slide super fast) for DIY lightning. Figure out how to recreate a family-friendly version of this spark by visiting the activity blog Learn Play Imagine .

Make a Bug Vacuum

cool science experiments to try

A Lesson in: Entomology

Scientists capture bugs for study using a mouth-powered vacuum, called an aspirator or a pooter. Kids can make their own version from a mason jar, then use it to gather ants (or other small insects) and observe them in action.

What you'll need: Pint-size mason jar with a two-piece lid Milk or juice carton Hole punch 2 bendy straws Tape Gauze pad

How to:  1. Open the milk carton along the seams and flatten it out. Use the inner lid of the mason jar as a template to trace a circle on the carton. Cut out the circle and punch two holes in the center about an inch apart.

2. Carefully slide the short ends of the bendy straws into the holes. Tape a piece of gauze pad around the end of one straw to prevent any bugs from getting sucked up.

3 Set the lid on the jar and fasten it in place with the ring.

4. To use your pooter, place the tip of the straw without the gauze near a bug. Put your mouth on the straw with the gauze, and gently suck in. The bug should travel up the straw and land unharmed at the bottom of the jar.

Take It Further Capture some ants in your bug vacuum, then use a magnifying glass to observe these remarkable insects up close. Open the jar and feed them a few drops of sugary water or corn syrup, or try giving them some birdseed. Ants live in colonies headed by a queen ant, and they can’t last long on their own. When you are done observing them, release your ants where you found them. (Note: Some ants bite, so be careful handling them.)

Tell Me More Ants were the Earth’s first farmers. For millions of years, certain species have been creating underground gardens where they grow their favorite fungus for food. They tend to their crops, bringing them water and even weeding out other fungi they don’t want.

A Smell Challenge

cool science experiments to try

A Lesson in: Olfactory senses.

Teach kids the importance of smell with this activity that asks them to use only their noses to identify objects. Can they sniff out the fish oil over the garlic cloves? The lemon juice over the orange oil? Homeschooling blogger Ana has the instructions at Babble Dabble Do .

Is This Soluble?

cool science experiments to try

A Lesson in: Mixtures 

Teaching children chemistry can become a fun, at-home activity as a weekend afternoon project or as part of their remote learning curriculum. One of the best experiments you can do is the mixing activity. With this exercise, children will learn the difference between soluble and insoluble substances. Do not worry! You can do it with ingredients you already have in your kitchen!

Ingredients

  • Oil (cooking oil, vegetable oil, olive oil, etc.)
  • Food Coloring
  • Transparent containers with a lid or transparent cups with a spoon to mix

Before you begin the activity, ask the children what each ingredient is—whether it is a solid, liquid, or gas—and what they think will happen when you begin mixing them. This guarantees a hands-on experiment that will allow the children to feel they are in control.

  • Mix the water and the sand. Children will notice there is a separation between both ingredients and that layers have formed, so it is an insoluble reaction.
  • Mix the water and the food coloring. Children will see them combine—the water turning into that color—and know it is a soluble reaction.
  • Mix the water and the table salt. The salt will disappear in the water, making it another soluble reaction.
  • Mix the water and the oil. This time, a clear layer will be formed, showing another insoluble reaction.

After these mixing activities, you can further this experiment by letting the children find other ingredients to mix with water and have them determine if that substance is soluble or insoluble. The main goal is to show them different reactions and layers.

For a clear example of this experiment, check out this video .
