Most of MOSI's displays would entertain the younger kids more than the teenagers. The one complaint I have is that many of their displays are often broken and/or closed leaving some room for improvement.
The facility was expanded and includes a dome IMAX theater which plays movies throughout the day. I would highly recommend watching one of the 30 to 40 minute movies (usually educational and documentary). The seating in the theater is reclined to allow for the best view of the movie. Sit towards the center of the theater for the best seats.
