This resource turns gravity and moons into a complete, ready to use review for Grade 6-8 earth science, covering the same NGSS standard from three different angles.

Sample questions include "What is the primary reason moons can be found in different orbital planes?", "How does the mass of a planet affect the orbits of its moons?", and "Why do some planets have more moons than others?"
