The Wisconsin Geological and Natural History Survey (WGNHS) has been serving Wisconsin for over 125 years. Part of the Division of Extension at the University of Wisconsin–Madison, WGNHS provides objective scientific information about the geology, mineral resources, and water resources of Wisconsin. We conduct research, map Wisconsin’s geology, and share information through our publications and outreach.

This is the link to the Publications Catalog that includes Wisconsin Data sets and maps for: Bedrock Geology, Groundwater, Surficial Geology, Rocks and Minerals, Soils, Precambrian Bedrock, Surface Water, Metallic Minerals, Topography, Nonmetallic Minerals, Climate and Weather, and Frac Sand.

This is a publicly accessible website that contains wonderful, Wisconsin based data. Maybe the writing from another Wisconsin HS science teacher provides some ideas for how these data could be used.

Wisconsin's Tornadoes for the current and a link to find historical tornadoes from past years (shown on map with details of each tornado). From National Weather Service.
