Printable worksheet for learning the phases of the Moon, featuring labeled diagrams and space to color.

It looks like you've uploaded a worksheet titled "Phases of the Moon", which is designed to help students understand and label the different phases of the Moon as it orbits Earth. However, there's an error in the directions: the diagram shows Mars instead of the Sun, which is incorrect for explaining lunar phases.

Let’s solve this step-by-step, clarify the mistake, and explain how to correctly complete the worksheet.

🔍 Understanding the Problem

The goal is to:
- Use the guide at the top (showing 8 phases of the Moon) to label and color the correct phase in each of the 8 circles surrounding Earth.
- The Sun should be on the left side (as indicated by "The Sun This Way").
- The Moon orbits Earth, and its phases depend on how much of the sunlit side is visible from Earth.

But here's the issue:
✔ The arrow says "Mars This Way" — that’s wrong.
✘ Mars is not involved in lunar phases.
✔ It should say "Sun This Way", which it does on the left.

So we can assume the intention was to show the Sun on the left, and the Moon orbiting Earth, with the eight positions representing the Moon’s location in its orbit.

🌕 Step-by-Step Solution

We’ll go around the Earth in a counterclockwise direction (standard for orbital diagrams), starting from the top right and moving around.

#### ✔ Key Concepts:
- The Sun illuminates the Moon from the left (since “Sun This Way” points left).
- The side of the Moon facing the Sun is lit; the rest is dark.
- We view the Moon from Earth, so we see only the part of the Moon that is both lit and facing us.

🔁 Order of Moon Phases (from New Moon to Full Moon and back)

1. New Moon – Moon between Earth and Sun → no illuminated side visible
2. Waxing Crescent – small lit sliver on the right
3. First Quarter – right half lit
4. Waxing Gibbous – more than half lit, right side
5. Full Moon – Moon opposite Sun → full face lit
6. Waning Gibbous – more than half lit, left side
7. Last (Third) Quarter – left half lit
8. Waning Crescent – small lit sliver on the left

> Note: "Waxing" means growing; "Waning" means shrinking.

🧭 Positioning Around Earth

Let’s label the 8 circles clockwise or counterclockwise based on standard convention.

Assuming the diagram has:

- Top: One circle above Earth
- Right: One to the right
- Bottom: One below
- Left: One to the left
- And four more at the corners?

Wait — looking at the image layout:

There are 8 circles arranged around Earth:
- Top-left, top-right
- Middle-left, middle-right
- Bottom-left, bottom-right
- And two more? Actually, let’s count:

From the image:
- Top center
- Right center
- Bottom center
- Left center
- Then one above-left, one above-right, one below-left, one below-right?

Wait — actually, it looks like 8 positions forming a ring around Earth.

Let’s assign them in order around Earth, going counterclockwise, starting from the top-right position (closest to the Sun).

But since the Sun is on the left, and the Moon orbits counterclockwise, the Moon starts near the Sun (New Moon) on the left side.

So let’s go counterclockwise, starting from the bottom-left (closest to Sun):

✔ Correct Labeling (Counterclockwise from New Moon)

Let’s number the positions:

1. Bottom-left (closest to Sun) → New Moon
- Moon between Earth and Sun → no light visible
- Label: New Moon

2. Left-center → Waxing Crescent
- Small lit crescent on the right side
- Label: Waxing Crescent

3. Top-left → First Quarter
- Right half lit
- Label: Quarter Moon (or First Quarter)

4. Top-center → Waxing Gibbous
- Most of the right side lit
- Label: Waxing Gibbous

5. Top-right → Full Moon
- Opposite Sun → fully lit
- Label: Full Moon

6. Right-center → Waning Gibbous
- Left side mostly lit
- Label: Waning Gibbous

7. Bottom-right → Last Quarter
- Left half lit
- Label: Third Quarter Moon

8. Bottom-center → Waning Crescent
- Small lit crescent on the left side
- Label: Waning Crescent

🖋️ Final Answer: Labels for Each Circle

Let’s now match the labels to the positions:

| Position | Phase |
|------------------|---------------------|
| Bottom-left | New Moon |
| Left-center | Waxing Crescent |
| Top-left | First Quarter |
| Top-center | Waxing Gibbous |
| Top-right | Full Moon |
| Right-center | Waning Gibbous |
| Bottom-right | Third Quarter |
| Bottom-center | Waning Crescent |

> 💡 Note: In the diagram, the Sun is on the left, so the Moon's phases progress counterclockwise around Earth.

🎨 Coloring Instructions

Use the guide at the top:
- Dark gray = unlit side
- Light gray/white = lit side

For example:
- New Moon: all dark
- Full Moon: all white
- First Quarter: right half white, left half dark
- etc.

✘ Correction to Worksheet

The text says "Mars This Way" on the right — this is incorrect. It should be "Sun This Way" on the left, which it already is. But if the diagram says "Mars This Way" on the right, that's a mistake.

👉 Fix: Ignore "Mars This Way". It should read "Sun This Way" pointing to the left, which it already does.

✔ Summary

To complete the worksheet:
1. Label the 8 circles counterclockwise starting from the bottom-left:
- New Moon
- Waxing Crescent
- First Quarter
- Waxing Gibbous
- Full Moon
- Waning Gibbous
- Third Quarter
- Waning Crescent
2. Color each phase according to the key at the top.
3. Ignore the "Mars This Way" label — it’s likely a typo.
