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! 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?


What Science Experiments Can I Do 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 science 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!

Using The Scientific Method With Kids

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

Note: The use of the best Science and Engineering Practices is also relevant to the topic of using the scientific method. Read more here and see if it fits your science planning needs.

Helpful Science Resources To Get You Started

    Easy Science Experiments To Do At Home

    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.

    Science Experiments By Age Group

    We’ve put together a few separate resources for different age groups, but remember that many experiments will cross over and can be re-tried at several different age levels. Younger kiddos can enjoy the simplicity and hands-on fun. At the same time, you can talk back and forth about what is happening.

    As kiddos get older, they can bring more complexity to the experiments, including using the scientific method, developing hypotheses, exploring variables, creating different tests, and writing conclusions from analyzing data.
