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.
- How can you tell a thing that makes light from a thing that sends it back?
- What do you think happens to a white paper in a room with no light at all?
- 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.
