Science and Our World

For more than 53 years COSI has believed in the importance of science education for learners of all ages. We strive toward a more science-literate society and take pride in being an important resource for the community helping our citizens make informed choices by learning about science through our exhibits, educational programs and experiences both in our building and throughout the greater Columbus community. COSI provides a lens for which you can access, interpret and understand science in every environment - where people live, learn and lounge.
