Moon Phases

The moon is a natural satellite that orbits around the Earth. It takes 28 days for the Moon to complete one revolution around the Earth. This is the same amount of time it takes for the Moon to rotate on its axis one time. The moon reflects light from the Sun which is why it appears bright in the night sky. As the moon revolves around the Earth, we can see different portions of the moon reflecting the Suns light. This is why the Moon appears to change throughout the month. In this activity you will learn more about how the Moon reflects light and make a tasty model of the different moon phases.
