S2.6.1 For the adult

Where light comes from

The Moon shines at night. Does the Moon make its own light?

What this chapter teaches

A light source makes its own light, such as the Sun, a flame or a lamp. The Moon, a mirror and white paper only send light back, and calling the Moon a source is the common mistake.

Three questions to ask

There is no one right wording. Listen for the idea.

  1. How can you tell a thing that makes light from a thing that sends it back?
  2. What do you think happens to a white paper in a room with no light at all?
  3. How would you show a friend that the Moon does not make its own light?

After the chapter, the learner can

  • Name things that make their own light
  • Tell a light source from a thing that only sends light back
  • Explain why you see nothing in total darkness

What they copy into their notebook

A light source makes its own light. The Sun, a fire and a lamp are sources. The Moon, a mirror and paper only send light back. With no light, we see nothing.
