Speaking of habitable, the atmosphere also contains the oxygen we need to breathe to support cellular respiration, the metabolic process that provides the chemical energy necessary for life. How much oxygen is in the air? This project will show you an interesting way to measure the percentage of oxygen in a sample of air in a test tube. The method depends on atmospheric pressure and a chemical reaction that removes oxygen from the air. So, what kind of chemical reaction can remove oxygen from the air? Oxidation of iron, also known as rusting, will do the trick. Exposed iron will rust in the presence of oxygen and water.
