Formation of Lake Superior

Students will put on a play to go through the steps of how Lake Superior formed by rifting of the Minnesota shore from the Wisconsin shore, erosion of mountains that were created from the rifting, and filling of the rift zone. Optional: discuss how the formations of Lake Superior also resulted in the formation of the different types of igneous (volcanic, from rifting and volcanic activity) and sedimentary (from sedimentation, or build up, of sediments from eroded mountains and other rocks) rocks we find in Lake Superior.
