This document provides information about classifying and identifying rocks and minerals. It includes directions for an in-class activity where students will classify rocks, label the rock cycle, and answer questions about rock and mineral formation. It also describes a review game where students answer questions as a group about topics like the three main rock types, what rocks are made of, how rocks are used, and processes involved in the rock cycle.

1. ROCKS REVIEW
16b – classify rocks by their formation
(igneous, metamorphic, sedimentary) (GPS)
16b1 – explain the rock cycle
16b2 – investigate the contributions of
minerals to rock composition (GPS)
16b3 – discuss the importance of mineral
and rock resources to society

2. PAGE 18
 Divide page 18 in your notebook in half (top and
bottom).
 On the top half, write and answer these questions
(be sure to leave room):
1. What are most rocks made up of?
2. How do we use rocks and minerals?
3. How are rocks classified?

3. PAGE 18
 Next, copy this flow chart. Be sure to put details of
how the rocks form:
Rocks
Clastic
Chemical
Organic

4. PAGE 18
 Finally, draw and finish labeling the rock cycle:
Igneous
SedimentaryMetamorphic

5. REVIEW GAME
 For each question, confer with your group, and
write your answer on your white board.
 Be quiet or else you will give away answers!
 If you talk when Mrs. Wilson is talking, you will lose
points for your team.
