Grades 4-8. Consists of 5 activities. This kit includes images that students analyze and stunning overheads that students use to relive Galileo's groundbreaking study of Jupiter's moons.

After they view the overheads, students perform activities that explore crater formation, scale modeling, and the Jupiter system as seen through the eyes of the Voyager unmanned probe.

For cooperative learning, students work in groups that form scientific settlements on one of Jupiter's moons.
