Our closest neighbor in space---the only other member of our solar system that humans have actually visited. This DVD answers questions such as---What keeps it revolving around the Earth?---Why do we only see one side of it?---What is the origin of the moon? Students will learn how the moon has been studied throughout history---including recent lunar missions---and about its phases, eclipses and how it causes tides on Earth. A fun hands-on activity will demonstrate the effect of the Moon's gravity on weight.
