Situated on the edge of the Inner Harbor, the Maryland Science Center is a big hit with tourists. In general, I found the exhibits very up to date and educationally oriented. It is perfect for school age children, and even adults, especially if you are someone who likes planetariums and IMAX films. The observatory is pretty cool too and the staff are excited to share their enthusiasm with visitors. The museum is open throughout the week and there are even extended hours in the summer. As I mentioned, the location is very convenient to other tourists destinatons along the harbor and closeby, such as the American Visionary Art Museum.
