This exercise was designed to address student misconceptions about why the Moon exhibits phases. Using a sketchbook, digital camera, or flex cam, a student sits at the center of a darkened room illuminated by a single light source in a stationary position. Stools are set up surrounding the student in the center and other students take those positions, always keeping their faces toward the center. The center student sketches or take pictures of the faces at each of the positions. Substituting a sphere (such as a ball) for the students' faces provides an even more vivid illustration of the shadowing of the sphere and connects directly to the rationale for lunar phases.
