Light and Shadow

All opaque (something you can't see through) and translucent (something you can see through) objects have a shadow. 

Shadows are made by blocking light. That might be light from the sun or anything with a light-bulb. When light hits something, everything that is facing the light is bright and lit up. But the object stops the light, which means the area behind the object will be in darkness.
