The impact and engagement of these STEM events will be amplified by the distribution of COSI Learning Lunchbox education kits. Learning Lunchboxes are interactive science kits filled with all supplies needed for five fun STEM activities and additional exciting learning resources. Fun for the whole family and perfect for school-age learners, all Learning Lunchbox content is aligned with national learning guidelines and standards.

frequently asked questions

This year, the COSI Science Festival will be 4 days, May 3 – 6, 2023. May 3 – 5 will be three days of events throughout Ohio, and the Big Science Celebration will be at COSI on May 6, 2023.

Community events will be spread throughout the state of Ohio. Not everyone can make it to COSI, and we want to ensure the COSI Science Festival is as accessible as possible.

The Big Science Celebration will be on May 6, 2023 at COSI.

Individual community events will be decided on a case by case basis, but the Big Science Celebration will be rain or shine. We’ll put in a request for sunny and 72, but we all know how Ohio weather is.

COSI is still open on the day of the Big Science Celebration, general admission rates apply.

Maybe you are working on a school project or are still curious about a topic after a visit to COSI. Ask our Department of Science Content your science questions! You can submit your questions here – cosi.org/contact-us.

There are a variety of ways. Each community will decide where the free Learning Lunchboxes will make the most impact, but kits are always available to be purchased online at cosi.org/kits, or in person at COSI. There area also a huge variety of free activities available through COSI Connects at cosi.org/connects.
