About every 28 days, the moon goes through a cycle. A cycle is a series of events that is repeated. As the moon revolves around Earth, we view the lighted part differently.

The view we see changes. The series of views repeats.
Click on a calendar day below to observe a model of the moon. Watch how the moon changes during a month.

Do It!


  • Paper
  • Pencil
  1. Try to observe the moon for at least five nights this month.
  2. Make drawings of what you see.
  3. Try to match your drawings to the calendar chart.
  4. What would your drawing look like if you observed on the same days the next month?
