50 Amazingly Simple Science Experiments for Kids at Home

Science Kindergartners Preschoolers Experiment Resources 32 Comments

Kids love experimenting , and these 50 simple science experiments for kids at home from Brigitte are perfect for all ages! Plus, you probably already have the basic supplies at home.

My daughters and I have had a lot of fun doing science experiments. Each year when we create our spring and summer list , we make sure to include “science days” which are days filled with science experiments.

Sometimes our science experiments don’t work according to plan, but I have been told that all scientists have failures with experiments from time to time.

It’s okay if they aren’t all successes.
