Folds and Faults (Teacher Page)
In this activity, students will learn why and how rock layers are folded and faulted and learn how to represent the structures in maps and cross sections. They will layer four colors of playdough to represent a horizontally layered rock mass with the oldest layer on the bottom. By pushing on the playdough block from two opposite sides, the students apply a compressive stress resulting in the folding of the layers into an anticline. After they have created an anticline in the layered playdough they will shave off the top, draw a map of the surface, and infer the interior structure.
