When it first opened it doors in 1970, the Science Center of Iowa was among the first interactive science museums in the world. It engaged the community with hands-on exhibits and programs. In 2005, the center moved to its 110,00-square-foot downtown location, where it fills its halls with a variety of experience platforms, each demonstrating different scientific principles. Build and launch a rocket in When Things Get Moving, learn about Iowa's native animals in What On Earth?, and explore the night sky in the Star Theater planetarium. A favorite of SCI's youngest visitors, Small Discoveries exhibit features features a farm-to-table theme with a market and kitchen for interactive play. For the “full experience”, catch a film in the 216-seat Blank IMAX Dome Theater, which features a six-story dome-shaped screen that surrounds your field of view and a 12,000-watt digital surround sound system that lets you hear everything from a tiny drop of rain to a huge clap of thunder with crystal clarity.
