Exploring the Phases of the Moon

The video explains why the moon appears to change shape in the night sky. It describes the moon's orbit around Earth and how this affects the visible phases, including new moon, crescent, quarter, gibbous, and full moon. The video encourages viewers to observe the moon and track its phases, highlighting that the moon itself doesn't change shape, but our view of its sunlit side does. The term 'month' is derived from the moon's cycle, which takes about a month to complete.

• The Earth's shadow covers different parts of the moon.
