Question

Moon phases quick check 8a science

Answer 1

Certainly! Here’s a quick overview of the phases of the moon, which can help in an 8th-grade science context:

1. **New Moon**: The Moon is between Earth and the Sun. The side of the Moon that faces Earth is not illuminated, making it invisible in the night sky.

2. **Waxing Crescent**: A small sliver of the Moon begins to show. The illuminated part is increasing.

3. **First Quarter**: Half of the Moon is illuminated and visible. It appears as a half-circle.

4. **Waxing Gibbous**: More than half of the Moon is illuminated and still increasing in brightness.

5. **Full Moon**: The entire face of the Moon is illuminated by the Sun, making it fully visible.

6. **Waning Gibbous**: After a full moon, the light begins to decrease, but more than half is still illuminated.

7. **Last Quarter** (or Third Quarter): Again, half of the Moon is illuminated, but this time the opposite half compared to the First Quarter.

8. **Waning Crescent**: A small sliver of the Moon is illuminated, but it is decreasing in size until it reaches a New Moon again.

### Key Points:
- The cycle of moon phases takes about 29.5 days.
- The changing positions of the Moon, Earth, and Sun create the different phases.
- The phases can be remembered with the mnemonic: "New, Waxing, First, Waxing, Full, Waning, Last, Waning."
