Plate Tectonics
Lesson/Demonstration #5a: Transform Boundaries
Guiding question: Why are there so many earthquakes in California and along the western coast of the United States?
Direct aims:
§ To understand what happens to the land at transform boundaries
§ To understand how plates move side by side as well as away from and toward one another
Indirect Aims:
§ Preparation for understanding different types of transform faults
§ Understand earthquakes, causes and effects
Materials:
Procedure:
Observation: Have students give verbal and written impressions and observations at this point in the lesson to demonstrate how they are thinking about transform boundaries.
Explanation for the teacher/science behind the work: The transform boundaries occur between plates that are sliding by each other in opposite directions. Transform Faults occur at these locations and there are frequent earthquakes.
Statement: Transform Boundaries are boundaries between plates that are slipping side by side. (NOTE: This statement can be used as a handwriting activity in student notebook.)

4. Geographic Map that shows plate boundaries
Procedure:
Observe: Do the plates move or stick? Is there sideways motion? What happens along the edges of the plates? What happens to the road?
Explanation for the teacher/science behind the work: The transform boundaries occur between plates that are sliding by each other in opposite directions. Transform Faults occur at these locations and there are frequent earthquakes.
Statement: Transform Boundaries are boundaries between plates that are slipping side by side.
