Phases of the Moon Lesson Overview



This activity asks students to use models of Earth, the Sun, and the Moon system to discover why moon phases occur. Students use a Styrofoam ball to represent the Moon, which will be lit by a single light source in the classroom, to observe how different portions of the ball are illuminated as they hold it in various positions. They create a complete series of phases matching the appearance of the Moon. And they relate moon phases to the positions of Earth and the Sun.
