Ithaca, NY

The Sciencenter (link) in Ithaca is the best children's science museum I've ever seen. The exhibits are attention-grabbing and (more impressively) attention-holding, even for an 8 year old. I've been twice in the past two days. We also did the Carl Sagan Planet Walk through Ithaca, which was a really cool way to think about relative sizes and distances in the solar system.
