Case Analysis

Passage

To understand day and night, the students perform a simple game. One student stands in the center as the 'Sun'. Another student, representing the 'Earth', stands at a distance and slowly turns around (rotates). As the 'Earth' student faces the 'Sun', they keep saying 'day... day... day'. When they turn away and can no longer see the 'Sun', they start saying 'night... night... night'. This activity shows that while the Sun stays in one place, the Earth's turning creates day and night.

Question 1: In this game, who stays at the center and does not move?

The student playing the 'Sun' stays at the center.
They represent the real Sun which stays in one place.

Question 2: What is the slow turning of the Earth called?

The slow turning is called rotation.
The 'Earth' student models this by turning in one place.

Question 3: When does the 'Earth' student experience 'night'?

Night happens when the student stops seeing the 'Sun'.
This occurs when they turn their back to the center student.
