Did you know...The mixture of gases in the atmosphere has taken over 4.5 billion years to evolve.About 99% of the atmosphere is made up of oxygen and nitrogen. The remainder is made up of argon, carbon dioxide and very small amounts of hydrogen, ozone, methane, carbon monoxide, helium, neon, krypton and xenon.

Finding the Amount of Oxygen in the Atmosphere: Lab
Background Information: The atmosphere of the earth is composed of a mixture of gases. The two most abundant gases are nitrogen and oxygen. Oxygen also appears in the earth’s crust combined with other elements to form minerals. By measuring volume, you can determine the percentage of oxygen in the air.
Objective In this investigation, you will study how much of the air is
consumed during combustion.
Problem: What percentage of earth’s atmosphere is oxygen?
Materials:
! Birthday candle ! 250-mL beaker ! 100-mL beaker
! Matches ! Wet-erase marker ! Large test tube
! Penny ! Water
Procedure: 1. Light the candle and let a few drops of wax drop onto the penny. Blow out the candle, and
place the candle upright on the penny in the wax. The candle should stick to the penny. 2. Fill the test tube with water. Using the graduated cylinder, measure this volume of water and
record it in the Data Table, #1. (The volume is also the volume of air in the test tube!) 3. Pour the water into the beaker. Carefully place the penny and the candle in the center of the
beaker. The penny should keep the candle upright. 4. Carefully light the candle, and rapidly invert the test tub over the lighted candle. Make sure
that the open end of the test tube is well under the surface of the water but not touching the bottom of the beaker.
5. As the candle uses the oxygen in the test tube, the candle will go out and water will be drawn into the tube to replace the oxygen.
6. When the candle goes out, carefully mark the level of the water in the test tube with the wet-erase marker. Remove the test tube.
7. Fill the test tube with water to this line. Using the graduated cylinder, measure this volume of water and record it in the Data Table, #2. (The volume is the volume of air in the test tube minus the oxygen that the candle used!)
8. To find the volume of oxygen originally in the test tube, subtract the volume of air after the candle goes out from the original volume. Record the volume in the Data Table, #3.
9. Determine the percentage of oxygen in the air by using the formula below. Record this percentage in the Data Table, #4.
% oxygen in air = x 100

Volume of oxygen in test tube . Total volume of air in test tube at start

Data & Results:
DATA TABLE
Conclusions:
1. Would the same result for the percentage of oxygen in air be obtained if a larger test tube was used? What about if a larger candle was used?
2. Why does the water rise in the test tube as the candle goes out?
3. Nitrogen is the other major component of air (78.1%). What property of nitrogen have you discovered as a result of this experiment?
4. How much oxygen is present in 5 L of air?
5. Why is oxygen such an important part of the earth’s atmosphere?
6. Based on your observations, what is an effective method of putting out a small fire
7. “As the altitude of an area increases, the density of the atmosphere decreases.” How can this statement be used to explain why it is more difficult to breathe in Denver, which has an altitude of more than 1500 meters, than in Houston, which is at sea level?
