Learning outcomes

Students will:

  • Recognize that the moon does not actually change shape, but goes through phases that form a pattern.
  • Learn that the amount of moon one can see each night depends on where the moon is in its orbit around the Earth.

Teacher planning

Time required for lesson

45 minutes

Materials/resources

Pre-activities

  • Students observe the moon for two weeks.
  • Students draw moon on the Moonwatch Activity Sheet each night for fourteen days.

Activities

  1. In a darkened room, the teacher will set up models of the sun, moon, and Earth.
  2. Moving the moon model slowly in a circle around the Earth, the teacher will instruct the students to draw the moon as it would be seen from Earth.
  3. Refer back to data collected on the Moonwatch Activity Sheet and pinpoint dates when the moon looks as it did in each point in this activity.
  4. Discuss and answer Moonwatch Questions.

Assessment

  • Completed activity sheets.
  • Verbal answers to questions.

Supplemental information

When collecting data on the Moonwatch Activity Sheet, it may be necessary for the students to infer what the moon actually looks like on any certain night, as some nights may be cloudy and the students may be unable to see the moon that night.
