This worksheet helps students visualize the moon's orbit around Earth while practicing the names of each phase.

Problem Description:

The task is to label and color the phases of the moon based on the guide provided at the top of the worksheet. The phases are listed as follows:

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

The worksheet shows a central Earth with eight blank circles around it, representing the positions of the moon during its phases. The directions indicate that the sun is on one side (left) and Mars is on the other side (right).

Solution Approach:

To solve this problem, we need to understand the sequence and orientation of the moon's phases relative to the Earth and the sun. Here’s how we can approach it:

#### 1. Understanding the Phases:
- New Moon: The moon is between the Earth and the sun, so it is not visible from Earth.
- Waxing Crescent: The moon is moving away from the new moon phase, showing a small illuminated crescent on the right side.
- Quarter Moon: Half of the moon is illuminated.
- Waxing Gibbous: More than half of the moon is illuminated, growing towards full.
- Full Moon: The entire face of the moon is illuminated.
- Waning Gibbous: The moon is shrinking from full, with more than half illuminated but decreasing.
- Third Quarter: Half of the moon is illuminated, but on the opposite side compared to the first quarter.
- Waning Crescent: A small illuminated crescent remains on the left side as the moon moves toward the new moon phase.

#### 2. Positioning the Phases:
- The phases progress in a counterclockwise direction around the Earth because the moon orbits the Earth in a counterclockwise direction when viewed from above the North Pole.
- The sun is on the left, so the new moon will be closest to the sun, and the full moon will be directly opposite the sun.

#### 3. Labeling and Coloring:
- Place the phases in the correct order around the Earth, starting from the new moon and moving counterclockwise.
- Color each phase according to the illumination shown in the guide at the top.

Step-by-Step Solution:

1. New Moon: This is the first phase, positioned closest to the sun (left side). It is completely dark.
2. Waxing Crescent: Next to the new moon, showing a small illuminated crescent on the right side.
3. Quarter Moon: Half of the moon is illuminated on the right side.
4. Waxing Gibbous: More than half of the moon is illuminated, growing towards full.
5. Full Moon: The entire face of the moon is illuminated, positioned directly opposite the sun.
6. Waning Gibbous: More than half of the moon is illuminated, but decreasing.
7. Third Quarter: Half of the moon is illuminated, but on the left side.
8. Waning Crescent: A small illuminated crescent remains on the left side.

Final Answer:

Label and color the phases in the following order (counterclockwise from the new moon):

1. New Moon: Completely dark.
2. Waxing Crescent: Small illuminated crescent on the right.
3. Quarter Moon: Half illuminated on the right.
4. Waxing Gibbous: More than half illuminated, growing towards full.
5. Full Moon: Entirely illuminated.
6. Waning Gibbous: More than half illuminated, decreasing.
7. Third Quarter: Half illuminated on the left.
8. Waning Crescent: Small illuminated crescent on the left.

The final labeled and colored phases should match the guide at the top of the worksheet.
