Need a hands on activity to help teach moon phases? This activity gets students up and out of their seats and working with the moon to figure out moon phases. Students will need styrofoam balls on skewers and a lamp in the middle of the room or one lamp per group. As they rotate like the Earth, they see the phases of the moon on their moon pop. This activity lets students get into the moon phases diagram to better understand how the revolution of the moon causes the phases to be seen on Earth. Also, this activity provides some good discussion points regarding why we don't have eclipses every month and why always see the same side of the moon.
