What’s in the Air?
To focus students, ask, Can we see the air in this room? Explain that air consists of a mixture of gases we cannot always see or smell. Ask students if they can name at least one molecule in air that humans need to live. You may need to remind them that we have to inhale this molecule (oxygen). Stimulate further conversation by asking, Besides oxygen, how many other kinds of gas molecules are in the air? (oxygen, nitrogen, carbon dioxide, argon, methane, etc.) Or ask, Is oxygen the only gas in air?
