I have been going here for almost 60 years. Starting as the Museum of science and industry and then massively expanding to what is there now. Entrance is free. Two floors of exhibits where usually 80% are working, which is good for a science museum. Go through the space exploration area, then reef exhibits. Lots of physics and mechanical displays. Human body area, auto safety, etc. Food is available down stairs and the gift shop is impressive. Do not forget the IMAX if you need a movie, that is not free.
