As you learned on the Help Me I Think I'm Changing page, each month the moon seems to change how it looks. Changes in appearance are called the phases of the moon.

The difference in the phases you see on earth is due to the moon's position as it revolves around the earth.

Search the Pioneer Library for the e-media video "The Moon Dance" to see why the moon phases appear different on Earth.

Try It!

Demonstrate how the sun, moon, and Earth are related as follows:


  • Two people
  • One sign for each person labeled Earth and moon


  1. The first person acts as the moon. This person is to slowly walk in a counter-clockwise circle around the person acting as Earth. As the moon person walks around the “Earth” person make sure the moon's face is always looking at the Earth person.
  2. Change roles with your friend so you both have taken the part of the moon and Earth.
