Shadows are like a game of hide-and-seek between light and objects. When an object blocks the path of light, it makes a shadow, kind of like when you stand in front of a flashlight and your whole body turns dark! The edge is clear because the light stops right at the edge of the object. It’s simple magic that happens every day.
Examples
- A tree casts a long shadow on the ground during the day because the sun is high up.
- Your hand blocks all the light from your face when you hold it close to your eyes.
- The moon makes a clear shadow on Earth when it’s directly between the sun and us.
