We need light to see. Light comes from light sources like the Sun, torches and lamps, and bounces off things into our eyes. When something blocks light, it makes a shadow.

Making shadows
Light travels in straight lines. When an opaque object blocks it, a dark shape — a shadow — appears behind it. Move the object closer to the light and the shadow grows. Outside, shadows are longest in the morning and evening and shortest at midday, when the Sun is high.
