Time Needed: One or two periods

Materials: Pictures of the changing phases of the moon for thirty consecutive days.

Procedure:

1. Hand out the pictures of the changing phases of the moon.
2. Elicit previous knowledge that students might have about the moon: Write the facts on the board.
3. Ask students to find the pattern in the changing areas of light and dark on the moon.
4. Ask students to describe the pattern. Write their descriptions on the chalkboard using their own words.
