Students will be able to:
use the information from laboratory experiments, the textbook and classroom discussions to
-determine how cellular respiration is affected by exercise.
Students reviewed HL 9.
Students then performed a lab to measure the effect of exercise on the production of carbon dioxide. Students measured the time it took to change the color of bromothymol blue from blue to green. This indicator changes color in the presence of carbon dioxide. The more cellular respiration that occurs in the body, the less time it takes to note a color change.
Students should complete the lab write up at home. It is due in class tomorrow.
