Sometimes a full moon can be so bright, you can walk around in the dark without a flashlight. How much brighter is a full moon than the other phases of the moon? How is the brightness of the moon measured?

Read about the birth of Earth's moon, its composition, orbit, visible phases, and other interesting facts. Link to a virtual moon phase interactive which shows the current lunar phase and the phase on any date in the past or future.

In this lesson, students are asked to order cards showing different phases of the moon. Includes student handouts.
