Gathering Data About Respiration

Students engage in an experiment that tests how much air we breathe in and out during the respiration process. For this respiration lesson, students blow a typical breath's amount of air into a balloon. They use a ruler to measure the width of the balloon, and compare the width to that of an abnormally large breath. They then chart their data and create a theory based on data obtained.
