The shape of the cliff changed when the rock it is made of changed.

# data[].attributes.body
-Landforms are made of rock (1.2)
-Even if geologists can't see a change happening, they can use models to visualize how it may have happened (1.6)
-Even though rock is hard, it can change shape (1.6)

# data[].attributes.body
How did the edge of the cliff get to be so close to the flagpole?

Assess level 3 understanding

# data[].attributes.body
-Rock breaks off when water hits landform.
-small pieces don't cause much change immediately
-changes seen over long periods of time

# data[].attributes.body
Assess level 2 understanding

# data[].attributes.body
-The shape of a landform changes when water hits it and causes pieces of rock to break off.
-Water hitting a landform causes tiny pieces of landform to break off

# data[].attributes.body
Assess level 1 understanding

# data[].attributes.body
-Landforms are made of rock
-Rock can change shape

Engage in SEPs and apply understanding of CCCs to gain understanding of core ideas

# data[].attributes.body
SEPs:
- investigate
- create
- obtain and evaluate
- develop models
- Ask questions
-Write explanations

CCCs:
- stability and change
- cause and effect
-scale, proportion, and quantity

# data[].attributes.body
- Water causes tiny pieces of rocks (which the cliff is made of) to break off. We don't see this change right away because the pieces are tiny.
- The nearby cliff eroded quickly because it is made of flimsy material.

Figuring out what caused the land to change shape will help students explain why the edge is closer.

# data[].attributes.body
Why is the shape of the land different than it used to be?

# data[].attributes.body
Why is the edge of the ocean cliff closer to the flagpole than it used to be?
