Lesson 1: The Moon's shapes

Grades K–2 · about 15 minutes · NGSS 1-ESS1-1. By the end: I can name the Moon's shapes and say that the Moon's shape changes in a pattern every month.

Learn

  1. The Moon doesn't make its own light. The Sun shines on it, and we see the sunny side.
  2. As the Moon goes around Earth, we see more of its sunny side, then less. That's why it seems to change shape.
  3. The shapes come in the same order every month: new, crescent, quarter, gibbous, full, and back again. It takes about 29 and a half days.

Try it

In a dark room, hold a ball at arm's length near a lamp and turn slowly in a circle. Watch the light on the ball grow from a thin slice to round and back.

Quiz: five questions

Four right is a pass. Peabody reads every question; tap a box.

Tonight's task

Look for the Moon on three nights this week (or in the morning). Draw its shape each time.
