Today in class we started looking at phases of the moon. We used a lamp in the middle of the room to represent the sun, our heads to represent the Earth, and a styrofoam ball on a stick to represent the moon.  We drew pictures to show the locations of Earth, sun, and Moon as well as to show where the light and shadows were on the moon.

This animation shows the locations of all three bodies as well as the appearance of the moon from earth.
