1. Essential Question: What is the composition of rocks and how are they formed?
Standards:
S6E5b. Investigate the contribution of minerals to rock composition.
S6E5c. Classify rocks by their process of formation.
S6E5d. Describe processes that change rocks and the surface of the earth.

2. Composition of Rocks Minerals
Rock fragments (smaller pieces of other rocks)
Organic matter (remains of organisms and their wastes)
Other natural materials

3. Rock Cycle
Shows the three types of rock and the processes that form and change them

4. Use the Rock Cycle Diagram

5. Let’s start with what you’ve learned so far…

6. How do Igneous Rock form?
Cooling

7. How do Metamorphic Rock form?
Heat & Pressure
Heat & Pressure

8. How do Sedimentary Rock form? Compaction & Cementation

9. Now let’s examine more ways that rocks can change

10. How would an Igneous Rock change to magma?
Melting

11. How would an Igneous Rock change to sediment?
Weathering & Erosion

12. Read the Weathering & Erosion Summary provided by the teacher
Read the Weathering & Erosion Summary provided by the teacher. When instructed, turn to an elbow partner and take turns describing each process.

13. How would a Metamorphic Rock change to magma?
Melting

14. How would a Metamorphic Rock change to sediment?
Weathering & Erosion

15. How would Sedimentary Rock change to sediment?
Weathering & Erosion

16. Compaction & Cementation

17. Which process in the Rock Cycle is similar to chewing gum?
With a partner, come up with an analogy for compacting of sediment. What about weathering and erosion?
