Edible Rock Recipes for Geology Lesson Plans

We are doing geology in Weaver right now. Suits my youngest daughter perfectly, as she loves to collect treasures from nature. When she was nearly 3 we took the girls to Disney World and as all the characters passed us by we found her collecting giant leaves. These days we have similar stories to tell about her collecting rocks.

You can visit my post on Making Your Own Rock Candy for lessons related to crystals and minerals. For the three basic rock types here are some recipes to make your geology lessons fun and hands on!
