2. Content Objectives
Students will be able to create a graphic organizer (foldable) illustrating and describing three rock types (igneous, metamorphic, sedimentary.)
Students will be able to identify three rock types (igneous, metamorphic, sedimentary.)
Students will be able to distinguish between weathering, erosion, and deposition.

3. Language Objectives
Students will be able to verbally define igneous rock, sedimentary rock, metamorphic rock, weathering, erosion, and deposition.

4. Key Vocabulary Weathering Erosion Deposition Igneous Rock
Sedimentary Rock
Metamorphic Rock

5. The Rock Cycle
The Rock Cycle
The rock cycle shows the three types of rock— igneous, metamorphic, and sedimentary—and the processes that form them.

6. Igneous Rocks
Igneous rocks are formed by cooling and hardening of hot liquid rock.

7. Metamorphic Rocks
Metamorphic rocks are formed when rocks are changed by heat and pressure.

8. Sedimentary Rocks
Sedimentary rocks are formed when sediments (small rock pieces) are pressed together and cemented (glued) together.

9. Open your treat! What is in a Rice Krispy Treat?
If this were a sedimentary rock, what would the rice krispies respresent?
What would the marshmallow crème represent?

11. Weathering
Weathering happens when rocks are broken down into smaller fragments.

12. Erosion
Erosion is when rock fragments are moved by some force of nature.

13. Deposition
Deposition is when rock fragments are laid down in a new location.
