Scientists have identified over 2000 different minerals in the earth's crust. 95% of the earth's crust is composed of about a dozen different rock-forming minerals. The rocks composed of these minerals can be formed in three different ways. Scientists can learn many different things about a rock by observing and classifying it.

In this investigation you will become very "friendly" with the rocks in your bag as you group them in different ways.

MATERIALS:
1 bag of rocks pencil ( ... )
