Exercise and Respiration

Students will investigate the process of respiration by investigating the question: How does exercise affect the amount of carbon dioxide exhaled? They will use bromothymol blue to time how fast it changes color before and after exercising. They will be guided into an understanding of the process of cellular respiration.
