1. Lesson 9:Moon Phases

2. Half of the Moon is always lit up by the sun
Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area.

3. The revolution of the Moon around the Earth makes the Moon look as if it is changing shape in the sky. 

4. This is caused by the different angles from which we see the lighted part of the Moon's surface.  These are called "phases" of the Moon. 

6. The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days.  The phases always follow one another in the same order:
New moon
First quarter
Third quarter
Full moon

8. First Quarter Moon
