A day and night working model demonstrates Earth's rotation on its axis to explain the cycle of day and night.
A light source (like a lamp) represents the Sun, illuminating one side of a globe.
As the globe rotates, different areas experience light (day) and darkness (night).
The model shows how the tilt of the Earth affects sunlight distribution.
This visual aid helps understand the relationship between Earth’s movement and the occurrence of day and night.
