Kids love experimenting, and these 50 simple science experiments from Brigitte are perfect for kids of 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.
50 Simple Science Experiments with Supplies You Already Have
I love these 50 simple science experiments for you to try with your little scientists. They all use basic household supplies that you probably already have at home!
Most of these are experiments my daughters and I have done together. I hope you enjoy them as much as we have!
Get little ones involved with these easy toddler-friendly science experiment ideas!
