Every night the moon looks a little different. This is because as the moon moves around the earth, sunlight shines on different parts of the moon. The part of the moon that the sunlight is shining on is the part of the moon we see. The moon goes through four main stages. The first quarter moon, full moon, third quarter moon, and new moon are the four stages. It takes about 29 days for the moon to finish all the stages. If it is a clear night, look in the sky. You will find the moon in one of its stages.
