Understanding Day and Night

The video explores the concept of day and night, questioning where the sun goes when it sets. It explains that the sun's apparent movement is due to Earth's rotation, not the sun moving. A model demonstrates how Earth's rotation causes different areas to experience day and night. An interactive game helps reinforce the concept, and the video concludes by summarizing that Earth's rotation is responsible for day and night.
