Science Standards:
Nature of Science and Patterns of Change

Objectives:

  • The student will make systematic and recorded observations of the Moon.
  • The student will describe the changing appearance of the Moon.
  • The student will predict the appearance and location of the Moon.

    Introduction:
    Many students are not aware of the changing appearance of the Moon. The Moon changes from a crescent in the western sky at sunset to a full Moon in the eastern sky in just two weeks. Conversely, for the next two weeks, observers see less and less of the lighted side of the Moon during the morning hours. The Moon is known as a waxing Moon during the first two weeks of its cycle and as waning during the last two weeks.

    Directions:
    1. Direct students to record the appearance and location of the Moon every evening for two weeks.
    2. Record student observations of the Moon on a calendar in the classroom.
    3. Students should speculate about the Moon's position and appearance when cloudy.
    4. Predict the completion of the calendar for remainder of the month.
