This is the equation for Cellular Respiration, basically all this means is that it requires energy to create energy. So what the lab does, is determines how much energy it takes from person to person to exercise and how CO production, Breathing Rate, and Pulse Rate fluctuate. In America we are so concerned about looks and fitness, but if this is true than why is there such a problem with obesity. Well, if you read, and understand what has been done in this lab, than you will be able to adjust your metabolism so as to help decrease, (or increase) your overall eight.

This lab does not help you change your metabolism, but shows the current average of the class. By conducting this experiment, believe that the obvious with show. That if you exercise for 1 minute and then 2 minutes than your breathing rate, pulse rate, and co production rate will increase because of the amount of time working out also increases.

Measure ml of tap water and pour into a small beaker 2. Using a dropper, add 8 drops of biorhythms blue (BET) to the water in the beaker 3. Using a straw, CAREFULLY exhale into the BET solution (CAUTION: Do not inhale the solution. Breathe in through your nose and out through your mouth) 4. Time how long it takes for the blue solution to turn yellow. Record the time in TABLE 1. 5. Wash out the beaker and repeat steps 1-4 two more times. Record data in TABLE 1 6. Average the results of the 3 trials. Record average in TABLE 1 7. Report your averages to the Class Data Table 1

After 2 minutes of exercise, immediately exhale CAREFULLY through the straw into the BET solution. Have your partner time how long it takes for the BET to turn yellow. Record the time in TABLE 1 5. Calculate your breathing and heart rates for both 1 and 2 minutes of exercise. Record these values in Tables 2 &3 6. Repeat steps 1-5 with your partner doing the exercise and record their data in the appropriate tables. Be sure that you and your partner do the same type of exercise. Group 1 min Conclusion: 2 min average

After fallowing the procedures listed on the earlier page, the class data was shown as such. This data matches my prediction almost exactly, my prediction was that as the rate of exercise increased so would the pulse rate, heart rate, and co production rate. For example, in Felid 1 for the increased heart rate data, the resting heart rate for that group is 91. 98 beats per minute, and as the amount of exercise increases so does the beats per minute. After 1 minute of exercise the group’s average heart rate is 1 28, and after 2 minutes the heart rate is 129 beats per minute.

To find these results the group first counted the amount of beats for one minute, then added the two answers together and divided by two, this gave them their average. Next, the group did push-ups for a full minute than count the beats per minutes and found the average. The last they ran for two minutes after running they counted there beats per minute and found the average again. For a short lab this system works fine, however this lab does not go without flaw. The lab would have gone more smoothly and had more accuracy if the exercises for the 1 minute and the 2 minute where he same.

The lab would have been more successful if the before working out for 2 minutes all of the groups waited for their heart rate, pulse rate, and co production went back to being the normal average. The purpose of this lab was to figure out how increasing exercise affects someone’s co production rate, pulse rate, and heart rate. To achieve this we secured for which ever amount of time needed, than recorded this information in the tables. The hypothesis was that as the time of exercise increases so would the rate of co production rate, pulse rate, and heart rate. The data show in the graphs and tables support this hypothesis.

For example, Panther Xi’s starting heart rate was 80 beats per minute, after 1 minute of exercise it was 98 beats per minute, and after 2 minutes of exercise was 127. 5 beats per minute. This may have happened the way it did because of cellular respiration, because as the body exercises more and more, the needs to use more TAP energy thus increasing your heart rate. Analysis: Well, as the beaker was filled with ml of water you add the BET (Biorhythms Blue Solution) the water becomes and stays the color blue. However, when enough co it introduced to the BET (Biorhythms Blue Solution) it turns yellow.

So we exercised for “x” amount of time than just breathed normally in the beaker and recorded the time it took to change color. From these test you can determine that because co production time decreases as the amount of exercise increases. So because of this you can conclude that the amount of co in your breath while “out of breath” is significantly increased. The same can be said about heart and pulse rate because as the rate of exercise increase so does both the heart rate and the pulse rate. This occurs because as the body has to strain to keep up with the amount of work being done.

You muscles use much of the TAP energy that your body has stored. My hypothesis was; “that if you exercise for 1 minute and then 2 minutes than the amount of time working out also increases”. My hypothesis is correct, as your body moves and exercises, than your body must do things to compensate those things are increase pulse rate, breathing rate, and co production. For future references, I would say that both exercises are the same, and that before starting he second exercise you make sure everything (heart rate, pulse rate, and co production) are back to normal.

Error Analysis: As far as a tenth grade lab is concerned, I believe that the lab was done well. However this information is not reliable by any means there are just to many unaccounted variables that were in the lab by mistake. For example, there was time elapsed after both exercises, there were some people who were sick during the lab, and many people did different exercises during the 1 and 2 minute exercises. To ensure valid results in the lab I recommend that the previous three examples are fixed, that during the time of exercise everything is ready and set up for testing.
