Bill Nye the Science Guy gets aerobic about the importance of respiration when he jogs, bikes, swims and scuba dives. Along the way, viewers will discover how to measure how much air each breath contains and make a model lung in a nifty home experiment. In addition, students will see a demonstration of how cigarette smoke can infiltrate and injure lungs. This live-action, fast-paced program also features comedy, music videos, interviews with real scientists and hands-on experiments to make the concepts presented understandable and fun.
