OBSERVATION TABLE

The effect of exercise on the rate of cellular respiration

Time-length of activity

Time for color change (sec)

0 min exercise

1 min exercise

ANALYZE AND APPLY

1. Make a graph of your results. Determine if the graph should be a line graph or a bar graph. Carefully

decide which variables belong on the X axis and Y axis. Remember to provide a title and to label

the X and Y axis.

2. Compare the time it took the bromothymol blue solution to change color before exercise and after

exercise. Explain why there was a difference.

3. Using your graph, predict the time of color change if the experimenter did exercise for 2 minutes.

4. In this investigation, we measured the amount of carbon dioxide produced to find the rate of cellular

respiration. What else could we measure to find out the rate of cellular respiration?

5. Explain why it is so important to exhale completely when doing exercise.
