"Tweens" is for kids "inbetween" childhood and being teenagers, considered by many to be a very important stage in a one's life (and I certainly wouldn't want to relive mine).

This new show reminds me somewhat of "The Voyage of the Mimi," which starred a very young Ben Affleck. The show was about science and nature, and in one episode they were shipwrecked and had to use survival skills. We saw it on LaserDisc when I was in fifth grade.
