They then are challenged to determine how exercise can affect the rate of cellular respiration by timing how long the bromothymol blue changes color before and after exercising. Includes access to pre-lab videos, editable lab instructions, downloadable student handouts, detailed background information, safety information, teacher notes with answers to all questions and sample data, and teaching and lab tips.
