Help Science Thrive!

Your generosity can inspire learners of all ages to discover how science is for everyone, everywhere—in the environment we live in, in the technology we hold in our hands, and in the molecular fabric we have in our bodies.

By donating to COSI, you ensure more people in our community have access to science education, learning, and fun!

If you have any questions during your online giving experience, please call 614.629.3122. Questions can also be directed to This email address is being protected from spambots. You need JavaScript enabled to view it.. We will gladly respond as soon as possible.

Thank you in advance for your generosity!
