Lunar CyclesGoal: Identify the phases of the Moon, and
relate the phases to eclipses.
Moon Phase Foldable
New Moon
The new moon phase occurs when the Moon is between the Sun and the Earth.
When this occurs, there is a possibility of having a solar eclipse.
Solar eclipses do not happen each month because the orbit of the Moon is 10o off from the orbit of the Earth.

Waxing Crescent
The Moon revolves around the Earth.
Waxing means to increase in size. This refers to the lit portion of the Moon.
Crescent refers to the shape.
Remember, the line dividing the light from the dark is called the terminator.
The terminator moves from right to left.

Full Moon
During the full moon, we see the light reflecting from the entire surface of the moon facing the Earth.
During this phase, it is possible to have a lunar eclipse.

Waning Crescent
The waning crescent gets smaller and smaller, until the Moon completes its orbit and begins a new cycle with another new moon.
