Step-by-step solution for: Phases of the Moon Worksheet | Science Resource | USA
It looks like you've uploaded an educational worksheet about the Phases of the Moon, which is a common science activity for students to understand how the Moon appears from Earth as it orbits around our planet.
Let’s go through the task and explain how to solve it step by step.
---
The Moon goes through eight main phases in its cycle, which are caused by its position relative to the Earth and the Sun. As the Moon orbits Earth, different portions of its sunlit side become visible to us.
The phases in order are:
1. New Moon – The Moon is between Earth and the Sun; the side facing Earth is not lit.
2. Waxing Crescent – A small sliver of the Moon becomes visible.
3. First Quarter – Half of the Moon is illuminated (right side in the Northern Hemisphere).
4. Waxing Gibbous – More than half is lit, growing toward full.
5. Full Moon – The entire face of the Moon is illuminated.
6. Waning Gibbous – After full moon, decreasing illumination.
7. Last Quarter – Half illuminated (left side).
8. Waning Crescent – A small sliver remains visible before returning to new moon.

There are two versions of the same diagram:
- On the left: A simplified version with labeled positions but blank circles below to draw what you see.
- On the right: A more detailed version showing the Earth, Moon orbit, and sunlight direction.
Both diagrams show the Moon's orbit around Earth, with arrows indicating the direction of motion and sunlight coming from the Sun on the right.
Each labeled position (A–H) corresponds to a phase of the Moon.
---
> *"In the black circles, draw what you would see from Earth."*
So, for each labeled point (A–H), you need to draw the appearance of the Moon as seen from Earth at that stage.
Let’s match each label to the correct phase and sketch description:
---
#### 1. A. First Quarter
- Half of the Moon is lit — the right half.
- Draw: A circle with the right half shaded (or unshaded depending on convention — usually, we shade the dark part).
✔ Sketch:
```

```
→ Right half is bright (sunlit); left half is dark.
#### 2. B. Waxing Gibbous
- More than half is lit, and it's increasing.
- The right side is lit, with only a small dark portion on the left.
✔ Sketch:
Mostly bright, just a small dark crescent on the left.
#### 3. C. Full Moon
- Entire face is illuminated.
- Draw: A fully white circle (no shading).
✔ Sketch:
```

```
→ Whole circle is bright.
#### 4. D. Waning Gibbous
- After full moon, so still mostly lit, but now the left side is starting to darken.
- Draw: Mostly bright, but a small dark section on the left.
✔ Sketch:
Same as waxing gibbous, but dark part is on the left.
#### 5. E. Last Quarter
- Half lit, but this time the left half is lit.
- Draw: Left half bright, right half dark.
✔ Sketch:
```

→ Left half is bright.
#### 6. F. Waning Crescent
- Only a small sliver is lit, on the left.
- The Moon is shrinking after full moon.
- Draw: Small curved bright edge on the left.
✔ Sketch:
```

→ Bright part on the left.
#### 7. G. New Moon
- The Moon is between Earth and Sun.
- The side facing Earth is not lit.
- Draw: A completely dark circle (no visible light).
✔ Sketch:
A plain black or empty circle (no markings).
#### 8. H. Waxing Crescent
- A small sliver is lit, on the right.
- The Moon is growing from new moon.
- Draw: Small curved bright edge on the right.

For each letter, draw the following in the black circles:
| Label | Phase | Drawing Description |
|-------|------------------|---------------------|
| A | First Quarter | Right half lit |
| B | Waxing Gibbous | Most lit, dark on left |
| C | Full Moon | Fully lit |
| D | Waning Gibbous | Most lit, dark on right |
| E | Last Quarter | Left half lit |
| F | Waning Crescent | Small lit sliver on left |
| G | New Moon | Completely dark |
| H | Waxing Crescent | Small lit sliver on right |
---
- Always remember: Sunlight comes from the right (in this diagram).
- The illuminated side is always facing the Sun.
- Use a pencil to lightly shade the dark parts of the Moon.
- In the Northern Hemisphere, the Moon "waxes" (grows) on the right side and "wanes" (shrinks) on the left.
---
To complete the worksheet:
1. Identify the phase at each labeled position (A–H).
2. Draw the visible appearance of the Moon as seen from Earth.
3. Shade the dark side appropriately based on sunlight direction.
This helps visualize how the Moon’s phases change due to its orbit around Earth!
