I can see why they bring the school kids here.
There are a lot of hands on type of items for kids to play with and "discover" things. There was also demonstration - little shows - with a host in different topics. My friend and I watched the subzero and part of the electricity one. The subzero one is quite cool since the guy played with liquid nitrogen.
While we were there, there was a race exhibit. This was quite interesting and thought provoking.
It was a bit pricey for what was being offered. They do offer a year pass. We didn't even go to the IMAX - that was extra. We were only there for a few hours before we saw everything we wanted to and left. Very educational though.
