The fifth annual Wisconsin Science Festival is taking place Oct. 22-25 at various locations around Madison and the state, organizers announced this week.

“This year’s ‘Made in Wisconsin’ theme offers a special opportunity to explore the science behind many Wisconsin products,” Kate VandenBosch, chair of the festival’s planning committee, said in a statement. “It is truly a celebration of Wisconsin ideas and the innovations that grow from those ideas.”

Many activities will take place at the Wisconsin Institutes for Discovery, including Friday’s hallmark event Made in Wisconsin. In this expo-styled event, visitors will experience established Wisconsin traditions and emerging entrepreneurial endeavors, sample Wisconsin fare and listen to an eight-minute flash talk from companies like Thermo Fisher Scientific and Raven Software.

Other events include a tour of Filament Games and a presentation titled “The Synergy of Art and Technology in Entrepreneurship.” Overall, the festival features more than 200 events at more than 30 communities, including La Crosse and Milwaukee.

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