PHASES OF THE MOON
• The moon does not have its own light.
• The sun lights it up.
• The moon circles the Earth, which causes the shape of the lit portion to change.
• So we see different parts of the moon while it orbits around the Earth.
• These changing shapes are called phases of the moon.
• Some days we can hardly see the moon because the side lit up is away from the Earth. This is called a New Moon.
• It then appears as a thin Crescent, and goes on to become a Half Moon.
• It then bulges out to become a Gibbous moon and finally a Full Moon.
• These stages are the waxing phase of the moon.

• After this, the cycle reverses and the moon appears gibbous, then a half moon, then a crescent, and finally a new moon again.
• This reverse cycle is called the waning phase of the moon.
