Teacher Note: Teacher can supply materials or have students come up with own

Choosing from the following materials, construct a moving model to show the movement and interactions of plate boundaries and explain your model.

Materials:

Styrofoam block

foam padding

clay

paper

Scoring Guide:

3 points 1 point for each boundary – divergent, convergent, transform

3 points 1 point for correct movement of each boundary

3 points 1 point for the correct explanation of what happens at each boundary
