What Are The Phases Of The Moon?

The Moon goes through eight phases as it orbits Earth, changing how much of its sunlit surface we can see. A complete lunar cycle takes approximately 29.5 days.

The eight phases of the Moon, in order, are:

1. New Moon – The Moon is barely visible from Earth.
2. Waxing Crescent – A small, growing crescent becomes visible.
3. First Quarter – Half of the Moon’s visible surface is illuminated.
4. Waxing Gibbous – More than half is illuminated, and the bright portion is increasing.
5. Full Moon – The entire visible surface appears illuminated.
6. Waning Gibbous – The illuminated portion begins to decrease.
7. Third Quarter – Half of the visible surface is illuminated again.
8. Waning Crescent – A thin crescent remains before the cycle starts again.

The words waxing and waning describe whether the illuminated portion is growing or shrinking. Crescent means less than half is illuminated, while gibbous means more than half.

These are some of the key science terms children can practice with the word search below.
