Phases of the Moon, Activity 5-2<br />
The student should be able to describe the phases of the moon in five stages (new to<br />
full).<br />
Background<br />
1. New moon<br />
2. Waxing crescent<br />
3. First quarter<br />
4. Waxing gibbous<br />
5. Full moon<br />

During the revolution of the moon about the earth, the relative positions of the sun,<br />
earth, and moon change. This causes sunlight to be reflected toward the earth by<br />
different portions of the side of the moon facing us. The changing positional relationships<br />
of the sun, earth, and moon caused by the moon’s orbit about the earth are<br />
responsible for the apparent changes in its shape as viewed from Earth.<br />
Procedure for the Classroom<br />
For several weeks prior to obtaining the STARLAB, students should observe the moon<br />
outdoors each night and report on its appearance and position in the sky.<br />
Procedure for the Planetarium<br />
• Using a star chart, set the projector for the appropriate date, time, and latitude.<br />
• (Optional) Set up the slide projector on its stand just to side of the entrance tube.<br />
• Using the STARLAB moon phases (or slide projector with moon phase slides),<br />
give students practice in identifying the different phases of the moon.<br />
• Demonstrate the general path the moon takes across the sky (east to westerly<br />
movement).
