Problem Analysis:
The worksheet is about understanding how shadows are formed based on the position of the light source (in this case, the sun) and the object (the tree). The task requires identifying the correct shadow for each given scenario.
#### Key Concepts:
1.
Shadow Formation: Shadows are created when an object blocks the path of light. The shape and size of the shadow depend on:
- The position of the light source.
- The orientation of the object.
- The distance between the light source, the object, and the surface where the shadow is cast.
2.
Sun Position:
- When the sun is high in the sky (near noon), shadows are shorter because the light rays hit objects more directly.
- When the sun is low in the sky (early morning or late evening), shadows are longer because the light rays hit objects at an angle.

Solution:
####
Question 1:
-
Sun Position: The sun is positioned to the left of the tree.
-
Shadow Direction: The shadow will be cast to the right of the tree because the sun is on the left side.
-
Correct Shadow: The shadow should extend to the right of the tree and match its general shape.
Answer for Question 1:
The correct shadow is the one in the
middle column (second option).
####
Question 2:
-
Sun Position: The sun is positioned above the tree.
-
Shadow Direction: When the sun is directly above the tree, the shadow will be directly below the tree and relatively small because the light is hitting the tree from a top-down angle.
-
Correct Shadow: The shadow should be directly beneath the tree and smaller in size compared to the tree's actual size.
Answer for Question 2:
The correct shadow is the one in the
left column (first option).

Final Answers:
1. For Question 1:
Middle column (second option).
2. For Question 2:
Left column (first option).
Boxed Final Answer:
\[
\boxed{\text{Middle column for Question 1, Left column for Question 2}}
\]
