Collect Oxygen Over Water

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen. Learners will test to see if they've generated oxygen by observing the combustion of elemental sulfur, which yields a brilliant blue flame of sulfur oxidation. The manganese dioxide catalyst used in this process is easily recovered from a spent zinc-carbon battery (see related activity).
