Why does nearly all life breathe oxygen? Student accidentally creates ... gases have other measurable properties: temperature (T), volume (V) and number of particles, which is expressed in ...

Alternatively, students could discuss the properties of oxygen and carbon dioxide as described in this clip. Challenge students to conduct a simple experiment to explore one of these properties ...

When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.
