Overlooking Lake Michigan, this well-conceived children's museum epitomizes the concept of hands-on learning. Playing on Wisconsin's agricultural economy, the museum lets kids learn the basics of commerce in an exhibit where they pick and sell play apples. Other perennial favorites are the BodyWorks exhibit, with its amusingly graphic mock-ups of bodily functions; nimble kids can crawl through a huge heart to see how blood flows from one chamber to another. Toddler play
spaces are well protected from the general flow of traffic.
