Air and Other Gases: CD-ROM, This second unit in the Applied Biology/Chemistry CD-ROM series examines the following topics: The Composition of Air; Gases and Pressure; Commercial Gases; and Maintaining Air Quality. Lesson one looks at air as a mixture of gases and examines the particles which make up those gases. It continues with the chemical composition of air and the location of gases throughout the atmosphere. Lesson two explains how air supports life, how gases cycle through Earth’s environment, and how organisms relate to atmospheric gases. Background information on the respiratory system of mammals is also provided, giving the student a clearer understanding of our dependence on a clean environment. Commercial gases are explored in lesson three and students will learn how air pressure and gases are used for fuel and in industrial processing. It also examines the hazards of many commercially useful gases. With this knowledge, students can move into lesson four which looks at the effects of gaseous pollutants in the air and what can be done to maintain air quality. Methods of detecting pollutants and determining mass and weight are also outlined.
