St. Louis, and particularly Forest Park, are full of free attractions, such as the Art Museum, History Museum, and the Saint Louis Science Center, also known as simply the Science Center. Part of the  Science Center is situated within in Forest Park, and the other part is situated in the small neighborhood of King’s Oak. The two sides are connected by a bridge that goes over interstate 64/40. As the name suggests, the focus of the museum, is science; however, the interactive exhibits have changed throughout the years demonstrating the changes in the field of science itself. Growing up, the Science Center was focused more on the natural sciences, such as geology, meteorology, and astronomy, but then began to focus more on building and architecture. Recently, the Science Center reflects the shift to STEM, with a large portion of the museum focused on space, aviation, simulators, and gaming.

Although the interactive exhibits have changed over the years, a few things have remained consistent, including large life-size electronic T-Rex and a Triceratops, the ability to build your own mini-arch, and a three-story ball maze. The Science Center consists of the large Planetarium in Forest Park, that is now home primarily to exhibits on Mars. The three-story structure on the other side of the highway is home to the omnimax, rotating exhibits, and three-floors of interactive exhibits. The Science Center also hosts an assortment of events throughout the year, such as workshops, movie showings, science experiments, and performances. On site there is also working labs where scientists are at work, and visitors can peer in on the process. Different events, visiting exhibits, and museum updates continue to provide visitors with a way to learn more and interact with science.
