The phases of the moon have interested people for thousands of years. Although often appreciated, they are not as often understood. Professor Lawrence A. Molnar of the Physics & Astronomy Department at the Calvin College provides this Java based tutorial that demonstrates lunar phases clearly and logically. It includes sections on time of day, time of month, and apparent direction of the moon. The Java demonstrations are meant to complement the simple yet elegant and powerful explanations of concepts. A typical demonstration involves a stick figure human on the earth's surface who can be interactively moved as the rotation of the planet is moved, to show how the phases change relative to time and direction. A quiz and teacher information are also provided.
