Abstract	Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the activities, which use materials commonly found in the home, are: (1) gases can push; (2) additional examples that gases can push; (3) air pushes upward; (4) compressed air changes temperature when it goes through a small opening into a place of lower pressure; (5) making of a mixture of solids; (6) making of a mixture of liquids; (7) fire needs air to burn; (8) candle wax vaporizes before it burns; (9) determination of the rate at which a candle burns; (10) a cooled flame causes incomplete burning; (11) relationship of carbon dioxide to burning; and (12) observation of carbon dioxide in exhaled air. Also included are a conclusion and summary of the experiments, and lists of facts about gases, materials needed for each experiment, and three other instructional resources available from the American Gas Association.
