Summary

In this exercise, students use gestures to re-create the motion of fault blocks adjacent to restraining bends and releasing bends. They then answer a few questions about a map view of the San Andreas Fault and two of its bends.

Learning Goals

After completing this exercise, students will be able to determine whether a curve on a fault surface forms a restraining bend or a releasing bend.

Context for Use

This exercise can be used either to have students discover or to review the concepts of restraining bends and releasing bends. It can be completed as a short in-class exercise or as homework.

Description and Teaching Materials

In this exercise, students use gestures to re-create the motion of fault blocks adjacent to restraining bends and releasing bends. They then answer a few questions about a map view of the San Andreas Fault and two of its bends.

Assessment

When we use this is an in-class exercise, we walk around the room, watching and talking with the students as they work through the exercise. It's a quick and easy way to assess student comprehension.

Using Gesture to Support Spatial Thinking highlights the value of gesture in communicating spatial information. It consists of two short exercises, and can be used in preparation for any other exercise in which students will be asked to use gesture to communicate spatial information.
