Moon Phases - Free Worksheet - SKOOLGO - Free Printable

This worksheet is designed to help students learn about the phases of the Moon. The task asks you to draw, color, and name each of the eight main phases of the Moon as they appear from Earth.

Let’s break it down step by step:

🔍 Understanding Moon Phases

The Moon goes through a cycle of phases as it orbits Earth (about once every 29.5 days). These phases are caused by the changing angles between the Earth, Moon, and Sun. The amount of the Moon that appears illuminated from Earth changes over time.

There are eight major phases in order:

1. New Moon
2. Waxing Crescent
3. First Quarter
4. Waxing Gibbous
5. Full Moon
6. Waning Gibbous
7. Last Quarter
8. Waning Crescent

> 💡 "Waxing" means getting brighter (increasing illumination).
> 💡 "Waning" means getting dimmer (decreasing illumination).

🌕 How to Fill Out This Worksheet

The diagram shows the Earth in the center, with eight circles around it representing the Moon at different positions in its orbit. Arrows show the direction of the Moon's orbit (counterclockwise).

We'll go clockwise starting from the top (following the arrow), and label each phase correctly.

#### Step-by-step guide:

1. Top Circle (Directly above Earth)
→ This is Full Moon
- The entire face is illuminated.
- Draw: Fully shaded circle.
- Color: Light gray or white for lit side.
- Label: Full Moon

2. Top-right Circle
→ Waning Gibbous
- More than half lit, but decreasing.
- Illuminated part on the left side.
- Label: Waning Gibbous

3. Bottom-right Circle
→ Last Quarter
- Half lit, right side dark.
- Label: Last Quarter

4. Bottom Circle
→ Waning Crescent
- A small sliver on the left side is lit.
- Label: Waning Crescent

5. Bottom-left Circle
→ New Moon
- No visible illumination (Moon between Earth and Sun).
- Draw: Completely dark (no shading).
- Label: New Moon

6. Left Circle
→ Waxing Crescent
- Small sliver on the right side lit.
- Label: Waxing Crescent

7. Top-left Circle
→ First Quarter
- Right half lit.
- Label: First Quarter

8. Middle-left Circle (between First Quarter and New Moon)
→ Waxing Gibbous
- More than half lit, increasing.
- Illuminated part on the right.
- Label: Waxing Gibbous

✔ Final Answer – Labels in Order (Clockwise from Top)

| Position | Phase Name |
|---------|--------------------|
| Top | Full Moon |
| Top-right | Waning Gibbous |
| Bottom-right | Last Quarter |
| Bottom | Waning Crescent |
| Bottom-left | New Moon |
| Left | Waxing Crescent |
| Top-left | First Quarter |
| Middle-left | Waxing Gibbous |

> ⚠️ Note: The arrows point counterclockwise, so the phases progress in this direction. But since the labels are placed outside each circle, you just need to fill them based on their position.

🖋️ Instructions for Drawing & Coloring

- Use black or gray to shade the unlit parts.
- Leave the illuminated side white or lightly colored.
- For crescent phases, only draw a small curved edge.
- For quarter phases, draw a straight line down the middle.
- For gibbous and full, most of the circle should be lit.

---

📝 Example:

- Full Moon: Entire circle filled with light.
- New Moon: Blank or black (no light visible).
- First Quarter: Right half lit, left half dark.
- Waxing Crescent: Thin bright curve on the right side.
- Waning Crescent: Thin bright curve on the left side.

🌙 Summary

You now know how to complete the worksheet! Just follow these steps:

1. Start at the top and go counterclockwise.
2. Fill in the names using the list above.
3. Draw and color each phase accordingly.

If you're doing this digitally, use tools to shade and write. If it's paper, use pencils or markers.
