For this assignment, you will develop and use a model of the Earth-Moon-Sun system to describe the
cyclic patterns of lunar phases and eclipses of the Sun and moon. You also will model and illustrate how
the tilted Earth rotates on its axis, causing day and night. You will then create a multimedia presentation
featuring your models.
