Step-by-step solution for: Shadows and the Sun (Year 3) | CGP Plus
I will solve the problem presented in the image, which is a worksheet titled "Shadows and the Sun." The worksheet contains three tasks. I will address each one by one.
Looking at the two pictures:
- In the first picture, the sun is high in the sky, positioned slightly to the right. A shadow cast by a stick would be short and fall to the left of the stick.
- In the second picture, the sun is lower in the sky, positioned to the left. A shadow cast by a stick would be longer and fall to the right of the stick.
The task requires drawing, which I cannot do. However, I can describe what the shadows should look like for a correct answer.

The options are:
- It changes length.
- It changes colour.
- It bends.
- It stays exactly the same.
- It moves.
Based on scientific knowledge of how shadows work:
- As the sun moves across the sky from morning to evening, the angle of its light changes. This causes the length of a shadow to change (longer in the morning and evening, shortest at midday).
- Shadows do not change color; they are areas of darkness.
- Shadows do not bend; they are projections of an object blocking light.
- Shadows definitely do not stay the same; their length and position change throughout the day.
- As the sun moves, the position of the shadow also moves across the ground.
Therefore, the correct answers to circle are:
- It changes length.
- It moves.
---
The options to match are:
Left column: Sunset, Midday, Cloudy day
Right column: Longest shadow, No shadow, Shortest shadow
Let's analyze each:
- Sunset: The sun is very low on the horizon. This creates the longest possible shadows for the day.
- Midday: The sun is at its highest point in the sky (closest to directly overhead). This creates the shortest possible shadows.
- Cloudy day: While clouds block direct sunlight, they do not eliminate it entirely. Diffuse light still comes from the sky, so shadows are very faint or soft, but not completely absent. However, in educational contexts for young children, "Cloudy day" is often paired with "No shadow" to represent the absence of distinct, sharp shadows.
Therefore, the correct matches are:
- Sunset -> Longest shadow
- Midday -> Shortest shadow
- Cloudy day -> No shadow

Here is the complete solution to the worksheet:
Task 1: For the first picture (sun high), draw a short shadow to the left of the stick. For the second picture (sun low), draw a long shadow to the right of the stick.
Task 2: Circle the following statements:
- It changes length.
- It moves.
Task 3: Match the items as follows:
- Sunset → Longest shadow
- Midday → Shortest shadow
- Cloudy day → No shadow
Task 1: Draw the stick's shadow in each picture below.
Looking at the two pictures:
- In the first picture, the sun is high in the sky, positioned slightly to the right. A shadow cast by a stick would be short and fall to the left of the stick.
- In the second picture, the sun is lower in the sky, positioned to the left. A shadow cast by a stick would be longer and fall to the right of the stick.
The task requires drawing, which I cannot do. However, I can describe what the shadows should look like for a correct answer.

Task 2: Circle the things that happen to a shadow caused by the Sun through the day.
The options are:
- It changes length.
- It changes colour.
- It bends.
- It stays exactly the same.
- It moves.

Task 3: Match up times of day on the left with the type of shadows seen on the right.
The options to match are:
Left column: Sunset, Midday, Cloudy day
Right column: Longest shadow, No shadow, Shortest shadow
Let's analyze each:
- Sunset: The sun is very low on the horizon. This creates the longest possible shadows for the day.
- Midday: The sun is at its highest point in the sky (closest to directly overhead). This creates the shortest possible shadows.

Final Answer
Here is the complete solution to the worksheet:
Task 1: For the first picture (sun high), draw a short shadow to the left of the stick. For the second picture (sun low), draw a long shadow to the right of the stick.
Task 2: Circle the following statements:
- It changes length.
- It moves.
Task 3: Match the items as follows:
- Sunset → Longest shadow
- Midday → Shortest shadow
- Cloudy day → No shadow
Parent Tip: Review the logic above to help your child master the concept of shadows worksheet.
