Our results show how information given out to the general public about a person's breathing rate is not necessarily true. They do not include how a small error underwater can effect the experiment's overall results. Our hypothesis was based upon the common knowledge of the human's respiratory system, not knowing about the effects of underwater complications.

The way we based our hypothesis was by observing the person being tested before hand. If one person was shorter than another we took that into account by making the shorter person's breathing rate less than the taller person's because the smaller person's respiratory system would be smaller. Also the short person would not need as much oxygen as the tall person because they do not have as much blood as the tall person. We also looked at how active a person was, their weight and any physical problems they had. This is how we got to the conclusion of our hypothesis.

When actually doing our experiment we were confident that our results would follow our hypothesis. However, we were wrong. Dylan C. was the only person tested who followed our hypothesis. The results of Ashley W., Caitlin T. and Emma H., fluctuated, going up and down. The reason for the fluctuation was errors that occurred during the experiment.
Emma H. had problems getting into the pool on time. This may have brought about stress, causing her to have a faster heart rate, thus affecting her breathing rate. This may not have happened if she was on time. Caitlin T. did not seem to have any major problems that would effect the overall results of our experiment. Ashley W. was following our hypothesis, until she had ear problems at ten feet. After a few minutes of rest, she recovered and returned to our experiment. It seemed that when she returned she was breathing as if she had just started the experiment. This may have happened because she was able to get out of the water, relax, and return to our experiment, as if she had started over.

With just a few minor glitches, our experiment was successful and we were better able to understand how our body's respiratory system functions.
