28 Edible Science Projects You’ll Actually Want to Eat

Have your science experiments, and eat them too!

Edible Science

Hands-on science experiments and projects are always a hit with kids, in the classroom and at home. Want to make them even better? Make them delicious, too! There are plenty of food and kitchen science projects out there, but not all of them are exactly tasty. That’s what sets this list apart from the rest: These edible science projects are actually good enough to eat! 

Of course, you’ll want to use common sense about safety and good food hygiene along the way. And don’t be afraid to substitute healthier ingredients for the candy and cookies, if you like. No matter what, you’re going to whet kids’ appetites for learning with this menu of edible science experiments. Bon appétit!

1. Candy DNA Model

Edible Science DNA Model

What kids learn: The structure and purpose of DNA

15. Apple Science

Edible Science Apple Browning

What kids learn: Chemical reactions

What to do: Slice an apple and note how it turns brown over time. Experiment with a variety of liquid solutions, including lemon juice, to see which, if any, slow the process. Discuss why or why not. Be sure to have students taste the apple to see if browning affects the flavor.

16. The Biology of Bread

Edible Science Bread Science

What kids learn: Fermentation, gluten formation

What to do: Bake a simple loaf of bread from scratch, using yeast. Watch the reaction of the yeast with water and sugar, then knead the dough to create the gluten the bread needs to support the rise. (You’ll need an oven to bake the bread to finish this edible science experiment.)
