This activity will help clarify to students that the seasons are created by changes in the tilt of the earth as it revolves around the sun, not by changes in the earth's distance from the sun. Using a light and a globe or ball, they will walk around the light to simulate the earth's orbit around the sun, making sure to keep the 'earth' tilted toward a specific wall of the classroom. They will observe how the amount of sunlight that hits a given point on the globe's surface changes, and answer questions about what they see.
