Context
• Physical Geology Hometown Geology Assignment (written assignment with maps/images) – students report on bedrock geology (tectonic history, type, features, etc) & issue of interest
• Goal of assignment – for students to apply and synthesize their knowledge of geology to a familiar context

Sequence (cont.)• Load bedrock geology data, explore bedrock & topography
• Change transparency of layers – identify relationships between topography & geology
• Explore rock types (types, features, tectonics)

Sequence (cont.)
• Focus directly hometown area for report using GeoMap App to link topography to geology
• Explore data sets/layers related to tectonic history and weathering/erosion of hometown
• Utilize additional online data sources
