Item #: FB1975
In the Exercise, Carbon Dioxide and Respiration Biology Laboratory Kit, discover the essential relationship between breathing and cellular respiration. Explore the body's complex biofeedback mechanism.
Exercise your students’ bodies—and their minds—to discover the essential relationship between breathing and cellular respiration! Students determine the relative amount of carbon dioxide in exhaled air before and after exercise using an acid–base indicator. Which sample contains a greater concentration of CO2? How and why do athletes train to increase their breathing efficiency? Students will answer these questions and explore the complex biofeedback mechanism by which the body uses the production of CO2 and pH to regulate breathing. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
