My daughters and I have done a lot of science experiments together over the years!
Density Experiment Make Glass Disappear A-maze-ing Potato Chemical Reaction Experiment Molecules Experiment Eggsperiment
Some of them we have only done once. I don’t think I’ll ever soak chicken bones in vinegar again. Not sure if we did something wrong, but that reeked!
Other science experiments have been so much fun (and simple) to do that we have done them multiple times. One such experiment is elephant toothpaste.

You can make your own elephant toothpaste using the step-by-step directions I provided on Hands On As We Grow (here). Make sure to scroll towards the bottom of that post if you’d like to download a PDF that includes the needed supplies and directions.

I also recently wrote an article for The Old Schoolhouse magazine about some more fun science experiments to do in the kitchen.
Yeast Experiment Toast Experiment
Make sure to check out “Science in the Kitchen” if you are interested in experimenting with roux, toast, yeast, and baking powder in your own kitchen.
All of the science experiments I shared in that article were adapted from the book The Science Chef: 100 Fun Food Experiments and Recipes for Kids and the course Breadmaking Devotional (found on SchoolhouseTeachers.com).
I also mentioned some additional books that encourage science in the kitchen including a few cookbooks for kids. Here they are for easy reference:
- The Magic School Bus Gets Baked in a Cake by Linda Beech
- Awesome Kitchen Science Experiments for Kids: 50 STEAM Projects You Can Eat by Megan Olivia Hall
- Kid Chef Junior: My First Kids Cookbook by Anjali Shah
- Super Simple Baking for Kids: Learn to Bake Over 55 Easy Recipes for Cookies, Muffins, Cupcakes and More! by Charity Mathews
- Cooking Class: 57 Fun Recipes Kids Will Love to Make (And Eat!) by Deanna F. Cook
