A lab was completed which involves the production of oxygen gas for use during the lab, the synthesis of iron oxide by inserting glowing steel wool into the bottle of collected oxygen, as well as the "sparkler" produced when iron powder is sprinkled over an open flame. The reigniting of a glowing wood splint was used to show the presence of oxygen. The oxygen was collected by a water displacement method which was devised in the classroom. The formal lab report will be written during tomorrow's class session.
