The Louisville Science Center in Louisville, Kentucky, has made an impressive journey from its founding as a "cabinet of curiosities" in the Public Library System of Kentucky in 1871 to its current status as the region's leading resource for informal science education. Boasting at one time little more than an Egyptian mummy and a 16,000-piece mineral collection, the Science Center is now the largest hands-on science center in Kentucky, with about 150 interactive exhibits, activity stations and a four-story IMAX Theatre.
