Granite cookies are fun to make and eat!

These kids science activities are fun and good to eat. You will be making granite cookies for this activity. Granite, diorite and gabbro are three main types of rocks that cool beneath the Earth's surface.

When magma (molten rock) cools beneath the Earth's surface crystals grow. The interlocking crystals do not form layers but are scattered through out the rock in random order similar to the cookies you will bake.
