Get ready for some serious science!

Ohio’s largest annual science event, the 2021 COSI Science Festival, is coming May 5 - 8, 2021. The third annual COSI Science Festival will include dozens of unique online events showcasing incredible science being done in Ohio and proving again that science truly is everywhere and for everyone.
