The sixth annual Wisconsin Science Festival is taking place Oct. 20-23 at various locations around Madison and the state.

Events include Saturday’s “Science Storytellers Jam,” a night of science entrepreneurs sharing stories, both educational and entertaining, and a panel of world-renowned speakers discussing “Big Ideas for Busy People.”

Similar to last year, many events will be held at the Wisconsin Institutes for Discovery.

Overall, the festival features more than 250 events at more than 90 venues and 30 communities, including Green Bay and Milwaukee.

Entry to many of the festival events are free, although some require minimal fees for materials.
