9. Curds and Whey
Little Miss Muffet sat on her tuffet, eating an edible science experiment! Use the science behind PH, proteins, and colloids to separate milk into curds and whey. Then turn the curds into cheese for a snack.

15. Baked Potato Science
This edible science project is a nutritious way to explore the scientific method in action. Experiment with a variety of methods for baking potatoes—microwaving, using a traditional oven, wrapping them in foil, using baking pins, etc.—testing hypotheses to discover which works best.

16. Edible Soil Layers
Layer a variety of foods to represent the soil layers, from bedrock on up. If candy doesn’t fit your school’s nutritional guidelines, use fruits, yogurt, granola, and other healthy options. Either way, the results are scrumptious!

17. Jell-O and Enzymes
Make Jell-O using raw pineapple, cooked pineapple, and strawberries to see whether the Jell-O sets properly. (You’ll need a heat source and a refrigerator for this edible science experiment.) Students can eat the results as you talk about the ways different enzymes affect chemical reactions.

18. Taste vs. Smell
Have students taste a slice of apple and then again while sniffing a cotton ball soaked in vanilla. Did the smell of vanilla overpower the taste of the apple? Students can finish their apples as you discuss how taste and smell work together.

19. Edible Cell Model
Use candies or fruits and nuts to represent the different parts of a cell. Kids can nibble as you discuss each item’s purpose and functions.

22. Jell-O Turbulence
Suspend a (well-cleaned) toy plane in Jell-O (instructions at the link below), then poke and jiggle it to simulate air turbulence. Discuss how layers of air can support a plane, even though you can’t see them.

23. Apple Reactions
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, exploring the concept of chemical reactions.

24. Bread Biology
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.)
Learn more: Bread Biology/Left Brain Craft Brain
25. Sourdough Science
Yeast makes bread rise, but you don’t have to buy it at the store. Make a sourdough starter using flour and water and watch wild yeast grow and multiply before your eyes. After a week or so, use the sourdough starter to make a savory loaf of bread.
