Check out the COSI app for fun at-home science discovery and learning! Every weekday, we provide exciting and engaging science through COSI videos and hands-on science you can try with your family at home through COSI Connects. Try a Science Challenge, participate in a Citizen Science activity, or take a virtual tour through the American Museum of Natural History Dinosaur Gallery. COSI, Columbus, Ohio's dynamic Center of Science and Industry, inspires the scientists, dreamers, and innovators of tomorrow. Opened in 1964 at Memorial Hall in downtown Columbus, COSI moved in 1999 to a new 320,000-square-foot home designed by internationally-renowned architect Arata Isozaki, creating one of the largest modern-built science centers in the United States.
