Air_Flame

Introduction:
What is air? Most people would agree that it is a mixture of different things. Air includes the oxygen we breathe in, carbon dioxide we breathe out, helium that escapes from balloons, odors wafting through the air, and more!

Procedure:
What kind of air supports a fire? We will test a candle flame in three different containers of air and compare them.


 * Air #1: Regular Room Air
 * Air #2: Exhaled Air
 * Air #3: Air from Dry Ice

We will fill the plastic containers with the right kind of air, place the containers over a candle, and see how long the candle stays lit. We will average our results and try to draw conclusions from the results.

Analysis:
1. What do you notice about the numbers? (Focus on comparing them in this box, not explaining why.) Was your group's data similar to the averages? 2. We know that flames need oxygen to burn. What did this experiment tell you about the oxygen level in each of the containers? media type="custom" key="4607630"
