Carnegie Science Center is a large hands-on science museum on the North Side riverfront. Its galleries cover technology, robotics, model railroads, space, and natural science, with plenty aimed at children but enough depth for adults.
The biggest extra draw is the USS Requin, a World War II submarine moored beside the museum on the Ohio River. It makes the center a good stop for families, science fans, and anyone looking for an indoor attraction near the stadiums.
