How Earth’s Rotation Creates Shadows!

 Hi Amazing Scientists!

Today, we’re exploring how Earth’s rotation makes shadows change throughout the day. Shadows are clues that help us understand how our planet moves!

Here’s what you need to know:

1. What do you need to know?

- The sun is at the center of the solar system

- There are 8 planets in the solar system. Earth is one of those 8 planets. The planets revolve around the sun.

- The sun DOES NOT MOVE.

Summary: 3 things happen at the same time:

- The Earth revolves around the sun. It takes one year, or 365 days, to complete one entire turn.
- While the Earth rotates around the sun, the moon rotates around the Earth. 
- Finally, the Earth rotates on its axis. It takes 24 hours for the Earth to complete a full turn.

3. Day and night cycle:
Our planet Earth rotates on an imaginary line called the axis of rotation. This movement is related to the 
origin of day and night.
On the half of the Earth that faces the sun, it is daytime. In the other half, it is night.
As the Earth rotates on its axis, the Sun appears to move across the sky. Each day,
the Sun appears to rise in the east, move across the sky, and then set in the west. In the morning and
late afternoon, the Sun is low in the sky. By noon, it is high inthe sky. On Earth, a day lasts 
about 24 hours. It is the same amount of time it takes the Earth to make 
one complete rotation.
Remember: the sun does not move. It is the rotation of the earth on its axis that makes the sun appear to move.

Shadows:
Why do we see shadows on the ground? 
Shadows are formed when an object blocks light rays (for example the sun), creating an area without light. 
The sun rises in the east and sets in the west, causing the shadows to change throughout the day.

What does the experiment show?
The position of the sun in relation to the object it creates the shadow determines its size and direction. 
A tree's shadow is longest in the morning and afternoon, and shortest at midday. 
This is because the sun's position changes throughout the day due to the Earth's rotation.
