"Shadow" PPT, part 4: discussion and exchange

Why is the shadow said to be a little black dog and a good friend?

Shadows are formed when light is blocked by opaque objects.

How are shadows produced?

Light travels in straight lines. When light encounters an opaque object, the light cannot pass through and a shadow is formed behind the object.

When the sun is behind you, your shadow is in front; when the sun is in front of you, your shadow is behind you;

When the sun is on the right, the shadow is on the left; when the sun is on the left, the shadow is on the right.

If you hide in a place without sunlight, you won't be able to see the shadow.
