Printable Grade 1 science worksheet where students label the day and night sides of the Earth and draw items seen in the sky.

Problem Analysis:

The worksheet asks students to:
1. Label the part of the Earth that is in daytime.
2. Identify which part of the Earth is in nighttime.
3. Draw what they see in the sky during daytime and nighttime.

Solution Explanation:

#### Step 1: Label the part of the Earth that is in daytime.
- The image shows the Earth with the Sun shining on one side. The side facing the Sun is illuminated, indicating it is experiencing daytime.
- The part of the Earth in daytime is the right side (where the Sun is shining directly).

#### Step 2: Identify which part of the Earth is in nighttime.
- The side of the Earth opposite to the Sun is not illuminated and is experiencing nighttime.
- The part of the Earth in nighttime is the left side (the darker portion).

#### Step 3: Draw what you see in the sky during daytime and nighttime.
- Daytime Sky: During the day, the sky is bright due to sunlight. You can draw the Sun, some clouds, and possibly a clear blue sky.
- Nighttime Sky: During the night, the sky is dark. You can draw stars, the Moon (if visible), and possibly some faint clouds.

Final Answer:

1. Part of the Earth in daytime: The right side of the Earth.
2. Part of the Earth in nighttime: The left side of the Earth.
3. Drawings:
- Daytime Sky: Draw the Sun, some clouds, and a bright blue sky.
- Nighttime Sky: Draw stars, the Moon, and a dark sky.
