Natural light and artificial light...today we worked on sorting sources of light into these 2 groups.
We found pictures of the sun, stars, fire, light bulbs, flashlights, and glow sticks. We even had someone draw a gun to show the light that is created when a bullet flows through the barrel (I have to admit Mr. Johnson had to be consulted on if this really happens)!
Here is something to think about...
Is a candle natural or artificial?
Some argued that a person had to make the candle, but the light comes from the fire which would be a natural source. But if the fire is started by a match it might be artificial.
This led to an interesting discussion at my dinner tonight, we would love to see what you think. Please feel free to add your comments below.
