Students will discover that the Moon changes its appearance from one night to the next; that these different forms of the Moon are called phases; and that they depend on the part of the lunar surface illuminated by the Sun that is visible from Earth. The activity has two parts, the first of which can be used to prepare students for the show, The Secret Phases of the Moon. ObjectiveTo better understand the mechanisms of the Moon's phases Equipment needed by the studentCopies of the activity sheet Scissors Glue stick or scotch tape Pencil (and eraser if necessary) Clipboard or a firm writing surface (to bring outside) PreparationFor each of the two parts, make enough copies of the activity sheets, one copy per student. AchievementThe first part of the activity introduces the concept of the order of the phases of the Moon and can be used before visiting the planetarium to prepare students for a better understanding of the show, The Secret Phases of the Moon. The second part consists of recording observations of the Moon for one month. It is best to begin the second part on a sunny afternoon, when the Moon is visible in the sky. This allows you to help students do some daytime observations during the early part of this activity. Students will then be able to use their skills to make their own observations, both during the day and at night.
