Shadow Movement Experiment

Observe how the position of a light source changes the shape and direction of shadows to understand light behavior.

What you need

• A torch/flashlight
• A small toy or object
• White paper or wall
• A pencil (for tracing)
• A dark room or corner

How it works

When the light source moves, the direction and length of the shadow change. This is because light travels in a straight line, and objects block light to create shadows.
