STANDARD I:  Students will understand that the appearance of the moon changes in a predictable cycle as it orbits Earth and as Earth rotates on its axis.

Objective 1:  Explain patterns of changes in the appearance of the moon as it orbits Earth.
a. Describe changes in the appearance of the moon during a month.
b. Identify the pattern of change in the moon’s appearance.
