A Yummy Geology Lesson

This post originated over at www.MiniMeGeology.com and we thought it was a fun idea to pass along to you! This is a yummy geology lesson that you can do with your kids while it’s too cold outside to start planning this year’s garden.

chocolate chip cookie with a bite outWhat can be yummier than chocolate chip cookies?  Well, they are a cool metamorphic rock experiment too!  Baking cookies is a great way to observe what can happen when a rock is metamorphosed because of high heat (like contact metamorphism).

This experiment is an easy way to describe metamorphic change to children because they can see that the raw and baked dough are the same ingredients that are changed by heat. All you need is your favorite cookie recipe. Each ingredient is a “mineral” that is mixed together with other minerals to create a cookie rock. When you expose the cookie dough to high heat in the oven, the dough turns into a metamorphic rock cookie!

This experiment is included in our Metamorphic Mystery Rock Detectives Kit.
