Exploring Shadows and the Sun's Influence

The video explores how shadows change in length and direction throughout the day due to the sun's position in the sky. It explains the concept of shadows, how they are formed, and how ancient civilizations used the sun's movement to tell time. By observing a lamp post's shadow from morning to evening, the video demonstrates the patterns in shadow length and direction, emphasizing that shadows are longest when the sun is low and shortest when it is high. The video concludes with an analysis of shadow data, showing that shadows point in the opposite direction of the sun.
