This Gathering Data About Respiration lesson plan also includes:
Young scholars engage in an experiment that tests how much air we breathe in and out during the respiration process.

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.
