Easy Science Experiments At Home for Kids

Science experiments at home are a fun way to engage the kiddos in easy-to-understand science concepts. They’ll want to do them over, over, and over again! At-home science puts the fun back into learning! One of the fascinating things about science activities for kids has to be the ease with which you can set up so many fun science experiments, even at home! The one thing that all of these experiments have in common is that they use everyday household supplies. How easy is that?

FUN AT-HOME SCIENCE EXPERIMENTS FOR KIDS

SCIENCE EXPERIMENTS AT HOME

Can you do terrific science experiments at home? You bet! Is it hard? Nope!

What do you need to get started? Simply get up, walk into the kitchen, and start rummaging through cupboards. You will surely find some or all the supplies you need for all the easy home experiments below.

These experiments at home work well with multiple age groups from preschool to elementary and beyond. Our activities have also been readily used with special needs groups in high school and young adult programs! More or less adult supervision depends on your kids’ abilities!

Read on to find out our favorite science experiments you can do at home that are do-able and make sense!

AT-HOME SCIENCE EXPERIMENTS

The following kids’ science activities can work for preschoolers through middle schoolers allowing multiple ages to work together while still learning great science concepts. Older kiddos can easily apply the scientific method, fill out science journal pages, and use science vocabulary to extend their learning.

BLOW UP A BALLOON

Of course, you know you can blow up balloons with your breath! What do you exhale? Carbon dioxide! But did you know you can also blow up a balloon with two common household ingredients, vinegar and baking soda?

Set up your experiment and test the difference between a balloon blown up with your breath and one blown up with the chemical reaction. Notice any differences?

CATAPULT PHYSICS

Explore potential and kinetic energy with a simple to make catapult. Our Popsicle stick catapult tutorial is perfect for testing physics in the living room.

Explore the weights of different objects and how far they fly. Play with the lever arm and fulcrum to test force. Run through Newton’s laws! Why not invent your own catapult? Craft sticks and rubber bands are the base for this project. A bottle cap to hold items helps too!

ERUPTING VOLCANO

This is a classic science project the kids will have a blast creating at home. Although it’s a multi-step project which involves homemade salt dough, and decorating a volcano to get started, the eruptions are awesome!

You’ll need a batch of salt dough (or old playdough), paint (optional), baking soda, vinegar, food coloring, and dish soap

GOOPY OOBLECK

Prepare to get a little messy with this science experiment! You might even want to take this one outside. All you need is cornstarch and water and food coloring (optional).

Have you ever heard of a Non-Newtonian fluid? Part solid and part liquid, oobleck is more than just water and cornstarch mixed together! It also demonstrates the properties of Non-Newtonian fluids. Pick it up like a solid and let it ooze back as a liquid.

GROW CRYSTALS

Growing crystals is a great way to explore saturated solutions and crystal formation with kids of all ages. If you don’t want to get into using borax powder to grow crystals (although very cool results), salt is another great option and really gets the kids involved.

Plan for the experiment to take a few days as the water has to evaporate. All you need is table salt, water. and paper!

MAGIC MILK

DIY milk fireworks! A fun way to explore chemistry and reactions with kitchen ingredients. What happens when the fat in the milk meets the dish soap?

No low-fat, fat-free options here. Full fat milk is the best choice for this home science experiment. You’ll also need food coloring, dish soap. cotton swabs, and a shallow dish.

MELTING ICE

This science activity features three different challenges that will keep the kiddos busy for hours and use items from around the house. Explore how ice melts, try to prevent ice from melting, and more. Simple science information included!

NAKED EGG

Can you really make an egg bounce or a rubber egg? What happens to egg shell when you have an egg in vinegar? So many fun ideas to test out with a few simple supplies. All you need is some uncooked eggs and vinegar.

SLIME SCIENCE

We love making and playing with all types of cool slime. From super fluffy slime, galaxy slime, butter slime, glow-in-the-dark slime, and more. But did you know that slime can also be a fun science experiment?

Explore what happens when you vary the key ingredients in one of our most popular slime recipes. You only need PVA glue, slime activators, and baking soda for tons of slimy fun.

WALKING WATER

Explore capillary action, the process that moves water up through the stem of a plant in order for photosynthesis to work! You can demonstrate this in several ways, including a walking water rainbow, color-changing flowers, and even with celery and lettuce leaves. All you need is food coloring, water, and something to move the water!

BALLOON ROCKET

How far can your balloon rocket fly? There’s an equal and opposite reaction for every action—exciting physics with straws, a balloon, and two anchor points.

MORE EASY SCIENCE EXPERIMENTS TO TRY

Are you looking for more cool science experiments to do at home? Here’s even more to try- kid approved! Little scientists, through big scientists, will love the selection of mixtures, models, and mess!

LAVA LAMP

This a classic must-do science experiment at home.

SURFACE TENSION

Pennies or pepper? Your choice or try them both as you explore two different surface tension forms. Pepper and soap is a classic science experiment!

DENSITY TOWER

You can explore the density of liquids (lighter, heavier) with various household liquids. Why do some liquids weigh more than others? Like solids, liquids are made up of different numbers of atoms and molecules.

TORNADO BOTTLE

Kids will love watching how a tornado forms in a bottle with dish soap!

ELEPHANT TOOTHPASTE

This classic science experiment usually uses a higher percentage of hydrogen peroxide, but did you know you can also use regular household hydrogen peroxide? YOU CAN!

CHICKPEA FOAM

Sensory play meets science lessons in emulsification and very hands-on science activity.

BAKING SODA VOLCANO

Kids love to build a baking soda volcano with a vinegar eruption. Go classic and build one out of homemade salt dough while you’re at it!

BUBBLES

Make a homemade bubble solution and explore bouncing bubbles, bubble shapes, and more. Can you blow a square bubble?

CABBAGE PH

Test acidity and make your cabbage PH indicator to test different solutions. Depending on the pH of the liquid, the cabbage turns various shades of pink, purple, or green! It’s incredibly cool to watch, and the kids love it!

RAIN CLOUD

Grab a sponge and a jar! What’s the weather? This is perfect for a spring or weather theme science lesson.

SCIENCE ART PROJECT (SALT PAINTING)

Combine fun science and simple art to get STEAM! Raised salt art painting with white glue and watercolors or food coloring is easy for various ages.

COLORFUL CANDY EXPERIMENTS

Fantastic candy science experiments that you can actually do with all of your favorite candy! Of course, you might have to allow for taste testing too!
