Lesson 9 of 14
Does it make its own light?
Show on a big screenMoonlight lights up a village at night. Where does it come from?
Step 1 of 3
- A star, a candle flame and a firefly (a glowing insect) make their own light.
- Sunlight falls on the Moon, Jupiter (a planet) and a coin. They shine.
- Switch the sunlight off. The Moon, Jupiter and the coin go dark.
The Moon does not make light. It bounces sunlight back.
The new words
- Luminous — makes its own light. The Sun, a star, a candle flame and a firefly are luminous.
- Non-luminous — does not make light. The Moon is non-luminous.
The rule
A source is a thing that gives out light.
A object makes its own light. A object does not. We see it when light from another source bounces off it.
Moonlight is mostly sunlight, bounced off the Moon.
Now try it. Tap what will still shine. Then switch the sunlight off.
