1. What is the pictures all about? Why we experience day and night?

2. What is Earth’s rotation? The movement of the Earth on its axis. One rotation is equivalent to 24 hours or 1 day. Its direction is from west to east, and it cause day and night. What is Earth’s revolution? The movement of the Earth around the sun. It takes 365 and 1/4 days or 1 year. It cause changes of the Earth’s climate such as summer,winter,autumn and spring.

3. LIST DOWN THE EFFECTS OF THE FOLLOWING EARTH’S MOVEMENT Earth’s Rotation Earth’s Revolution

4. Group Activity Make a role play about the Earth’s rotation and revolution.

5. In a calendar , there are only 365 and ¼ days. Therefore, every four years gain an extra day. The extra day is added to February every four years, February has 29 days. The year with additional day is called” leap year ”. Science Fact
