Publisher's Synopsis
From ancient times people have studied the heavenly bodies and their movements in space. Today, the rapid development of technology has given us a new understanding of Earth, our solar system, and the universe. The activities in this self-directed learning unit encourage your students to discover how the ideas about our solar system have changed over time. They can draw pictures or make up a song to show how moons from different planets are different or alike, make a collage of the special items astronauts need to survive in space, or find out how ancient peoples read the night sky to navigate, plant crops, and keep track of time.
