The Phases of the Moon

Ever wonder what's meant by the "dark side" of the moon? This interactive website allows visitors to explore why the moon has a dark side as well as how the moon revolves around the earth. Demonstrations show how the number of days in a month were determined and how the moon has a part in that as well as the phases of the moon. A short quiz at the end assesses what the user has learned.
