Quite a diversity of available content. I took my 4 year old and most of it was too advanced for him, but there was still a lot that engaged him at his level. I would imagine that an 8 year old would get quite a lot more out of the experience. We managed to fill a day from about 9:30 to 5, taking a long lunch break. You get stamped for admission and have a receipt, so for all of the general admission attractions you can actually leave to go out to grab a bite to eat and come back again. They have a good quality bistro in there but it isn't cheap either. Gift store inside with lots of educational type toys.
