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. The When Things Get Moving exhibit invites visitors to build rockets and conquer a domino obstacle course, and Why the Sky? demonstrates the science of space with a digital planet-exploration globe and the Cosmic Jukebox, which allows you to create your own show. Interact with exhibits that demonstrate the basic principles of physics in the themed scenario, the Eureka! Lab. The renovated Small Discoveries exhibit features Dahl's Produce Market and Edna's Kitchen, a favorite of younger visitors.
