Since its launch in 2011, the Wisconsin Science Festival continues to spark curiosity in residents of all ages.
October in Wisconsin means cooler weather, colorful leaves and the Wisconsin Science Festival. For 10 days, hundreds of events scattered across the state introduce residents to the wonders of science. In Madison, that included fun activities around the Capitol Square, a window into our past at the UW Geology Museum and experiments to engage the senses at the Wisconsin Energy Institute, just to name a few.
The popular Science on the Square event on October 15, 2026 featured activities that made the most of autumn’s early darkening skies.

Ingersoll Wonders of Physics Museum, located in UW’s Chamberlain Hall, includes a variety of exhibits that give learners of all ages hands-on experience with physical concepts.

The device is used across a growing network of weather and soil monitoring stations in Wisconsin.
