Question

Describe an activity to show the blue zone of a candle flame is the hottest

Answer 1

wooden toothpicks or matchsticks

a metal spoon

a bowl of water

First a warning. We will be using the candle flame to burn the toothpicks. Be sure you have an adult with you and use common sense. Don't burn plastics as some of them produce toxic fumes when they burn.

Light the candle and look carefully at the flame. At the bottom, you will see an area of blue flame. Above that is the yellow part of the flame. If you look carefully, you will see a darker area in the center. If you look very closely (be careful not to burn your nose) you may also see a very thin layer of blue flame over the entire surface of the flame.
