Lunar Phase

We just learned about the Solar Eclipse.

A full moon is when you can see the whole moon bright in the night sky.

What about when the moon isn't full and only part of it is showing?
Or when you can't see the moon at all in the sky?

The changing of the moon in the sky is called the lunar phase.
The light on the moon changes because it orbits the earth, and when the part we can see does not have sunlight shining on it, it is dark.
When the sunlight is shining on it all the way, it's bright.
