Description of the activity/assignment
Students examine geologic and topographic maps of Crater Lake in order to describe the shape of a stratovolcano and the rocks of which it is composed.
Determining whether students have met the goals
Working alone or in groups, students write a brief report synthesizing what they have learned from the maps. I evaluate the report using a rubric.
