Exploring the Moon

is a teacher's guide for learning about lunar geology and regolith (loose material on the moon's surface), distance to the moon, Apollo landing sites, and life support systems. Lessons focus on calculating the distance between scale models of earth and the moon, designing a spacecraft for travel to and from the moon, the locations and geology of the six Apollo landing sites, and calculating the diameter of the moon using proportions.

Interesting Fact:

When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low density magmas rise forming crusts. This process is called differentiation. Soon after formation, the Moon melted substantially forming a large body of magma that completely surrounded it. This is called the lunar magma ocean.
