1. Lunar Phases

2. Daily Demo

3. I Do
KP1 The Moon is visible because SUNLIGHT reflects off the moon’s surface.

4. I Do
KP2 At all times, only half of the moon’s surface is lit by the sun. The other half is in shadow. (Just like the Earth. (And all spherical objects.))

5. KP3 The Moon orbits the Earth once every 27 days.

6. KP4 As the Moon revolves (NOT rotates), our view of the moon changes.

7. KP5 Thus, the moon goes through a LUNAR PHASE cycle once every 27 days.

8. KP6 Our calendar is roughly based on this cycle.

9. KP7 When the moon is growing brighter, it is WAXING
KP7 When the moon is growing brighter, it is WAXING. When it is growing less bright, it is WANING.
