I thought it would be helpful to put our most popular science experiments in one place for you. Make sure to bookmark them to use all year round. The one thing I really like about how we do science and STEM here is that we do it simply.

We don’t use complicated or expensive materials. Plus, we don’t do complicated set ups, just tons of fun and hands on learning. Because we want everyone to be able to access science. Most importantly, we want it to be easy!

My son and I really like playful science activities since he is still a young scientist who likes to play! Right now we keep science simple to encourage a real love for the subject.

Before I share with you my 12 best science experiments, I want to give you a list of a few more awesome resources you will want to check out. Plan a year of science using all our ideas, and you will have an awesome year of learning.

One of the neat things about our fun science activities is that they can be given holiday or seasonal themes so easily. Plus, we have so many of those ideas for you! Just check out our YEAR OF SLIME THEMES to see how easy it is.

Over the last couple years I have really noticed how much fun my son has with all our holiday themed science and STEM experiments, so we do a lot! Most importantly, he enjoys learning.

I consider our best science experiments perfect for preschool, kindergarten, and early elementary. However, there are tons of ways to modify experiments to meet your kids abilities. Some may need more adult help and some less. Older kids can help younger kids.

Make Slime 

Our classic homemade slime recipe is perfect. You will also find alternative recipes for making slimes. We think making slime is one of our best science experiments.

We love making catapults and have a variety to check out, but we always go back to our popsicle stick catapult.

Dancing Corn

This is a fun fall themed take on the classic dancing raisins experiment.

Check out the physics involved in creating a zip line. It’s great hands on science for kids that is definitely playful!

Balloon Baking Soda

Seed Jar Science

I absolutely love this science activity because of the close up view you get to watch seeds grow. It’s not a playful science activity but it sure is cool to check out the new sights each day.

Frozen Dinosaur Eggs

Ice melting is a classic science experiment, and there are so many things you can add to ice. Think about your kids favorite themes and see what you come up with. We like our frozen dino eggs!

Homemade Lava Lamp

What happens when oil and water mix? What happens when you add a secret but common household supply?

Can you create a rainbow with just sugar, water, and food coloring?

Simplified Egg Drop Challenge

How about an egg drop challenge the younger kids will love. I love the classic engineering egg drop challenge, but this one includes the younger kids too!

Apple Eruptions

Chemical reactions are awesome for kids because they have a WOW factor that is cool every time. We have a whole collect of fizzing and popping science experiments. This one is always a favorite though. Fun for fall too.
