Lunar Phases Web Tool
Intended for use in introductory astronomy courses, this Java-based tutorial 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 explanations of concepts. A typical demonstration involves a stick figure human on the earth's surface, which can be interactively moved as the rotation of the planet is moved, to show how the phases change relative to time and direction. Teacher information and a quiz are also provided.
