This little museum, nestled in the corner of the American Heart Association building, just recently opened to the public. Exhibits show how the heart works, heart sizes of various animals, and how to make healthy heart choices. We stopped by for their grand opening weekend with my 4 and 2-year-old boys. The two-year-old enjoyed playing grocery store and listening to his heart beat. My 4-year-old thought it was cool to see and hear the heart beats of elephants and monkeys. He also liked trying to roll balls through a mock healthy heart valve verses an unhealthy one. The hands on exhibits are fun for little ones but also educational for kids a little older. I learned that my body has about a gallon of blood while my infant has only a cup. There was a theater where the kids watched a video about heathy heart choices. The museum workers were very excited about their jobs and eager to help us learn the most we could from each exhibit. There are kiosks at each exhibit where a video explains the purpose behind it. We spent about an hour here, but with my older kids (ages 6 and 9) I think we could have lasted a little longer actually learning from the exhibits instead of just pressing buttons and playing. This is a great little museum to learn about the heart. I'd recommend it for ages 3 and up, but think 5 and up would enjoy it most.
