A shadow is a dark shape that appears when something blocks light.
Here's a breakdown to help you understand:
- When light shines, it travels in straight lines.
- If something like you, a tree, or a toy gets in the way of the light, it stops the light from going straight through.
- The place where the light is blocked becomes dark because the light can't reach it. This dark area is the shadow.
- Opaque objects (things you can't see through) make clear, dark shadows.
Think of it like this: when you stand in the sunlight, your body blocks the light and creates a shadow on the ground. The shadow has your shape because your body is preventing the light from reaching that spot!
