A candle needs air
Tuesday, November 11th 2008
Teacher lit a candle. She put a glass (full of air) over the candle. The candle burned inside the upside-down glass for a while.
Then it went out because the burning candle used all the air in the glass.
Teacher tried again, this time with a jar. 
The candle burned for longer because there was more air in the jar than in the glass. We counted how many seconds each candle burned for.
