Science doesn’t need to be complicated or difficult and these easy science experiments below are awesome for kids! Visually stimulating, hands-on, and sensory-rich which makes them both fun to do and perfect to teach simple science concepts at home or in the classroom. Also check out our top STEM activities.
EASY SCIENCE EXPERIMENTS FOR KIDS!
HANDS ON SCIENCE ACTIVITIES
Kids are curious and always looking to explore, discover, check out, and experiment to find out why things do what they do, move like they move, or change as they change! My son is now 12 and we started around 3 years of age with simple science activities. Here’s our very first experiment.
Science learning starts early, and you can be a part of that with setting up science at home with everyday materials. Or you can bring easy science experiments to a group of kids in the classroom!
We find a ton of value in cheap science activities and experiments. All our science experiments below use inexpensive, everyday materials you can find at home or source from your local dollar store. We even have a whole list of kitchen science experiments, using basic supplies you will have in your kitchen.
You can set up these science experiments as an activity focusing on exploration and discovery. Ask questions, discuss what is happening and talk about the science behind it.
You can also introduce the scientific method, and get kids to record their observations and make conclusions. Read more about the scientific method for kids to help you get started.

TOP 10 SCIENCE EXPERIMENTS
If you only have time for one or two science experiments, here’s our suggestions. Our top 10 science experiments for kids are our most popular science experiments of all time and have been done, again and again! You will even find some fun theme variations for a few of these kids science projects.
Click on the titles below to get the full supplies list and easy step by step instructions. Have fun trying these experiments at home or in the classroom, or even use them for your next science fair project!
1. Baking Soda Balloon Experiment
Can you make a balloon inflate on its own? Just a few simple ingredients from the kitchen, baking soda and vinegar, and you have amazing chemistry for kids at your fingertips.
We also have a fun Halloween balloon experiment and a Valentine balloon experiment.
2. Rainbow In A Jar
Enjoy finding out about the basics of color mixing all the way up to the density of liquids with this one simple water density experiment.
3. Magic Milk
This color changing milk experiment is an explosion of color in your dish. Add dish soap and food coloring to milk for cool chemistry!
We even have done it as a Christmas experiment and for St Patrick’s Day science.
4. Seed Germination Experiment
Not all kids science experiments involve chemical reactions. This science experiment for kids is lots of fun because they can see how a seed grows for themselves. It is also a great experiment to introduce the scientific method to kids as it is easy to vary the conditions the seeds grow under.
5. Egg Vinegar Experiment
One of our favorite science experiments, also called a naked egg or rubber egg experiment. Can you make your egg bounce?
6. Dancing Corn
Find out how to make corn dance with this easy experiment. Also check out our dancing raisins and dancing cranberries.
7. Crystal Seashells
Growing borax crystals on seashells is actually very easy to do and is a great way to learn about solutions. You could also grow sugar crystals or salt crystals.
Growing crystals is great for themed science. Check out these fun ideas…
8. Lava Lamp Experiment
Great for learning about what happens when you mix oil and water. A cool science experiment kids will want to do again and again!
Check out these fun variations…
9. Skittles Experiment
Who doesn’t like doing science with candy? Try this classic skittles science experiment and explore why the colors don’t mix when added to water.
10. Lemon Volcano
Watch your kids’ faces light up and their eyes widen when you test out cool chemistry with common household items, baking soda and vinegar.
We have so many fun variations of this fizzing, erupting chemical reaction you will want to try. Check out a few below…
