Investigation on Effects of Exercise on Breathing Rate

1. Describing Differences Between Levels of Exercise

   • Describe differences in breathing rate across different exercise intensities.

2. Explaining Experimental Differences Using Biological Knowledge

   • Explain variations between experiments using biological concepts.

   • Address why breathing rate increases with intense exercise:

     • Identify the increasing metabolic process in cells.

     • Explain how metabolic products affect breathing rate/depth.

     • Justify the necessity of increased breathing rate/depth.

   • Incorporate various synoptic ideas from the course to explain results.

Evaluating the Experiment

1. Limitations and Accuracy

   • Identify experimental limitations.

   • Explain how limitations affected result accuracy.

   • Propose improvements to reduce limitations and enhance accuracy.

2. Repetition, Reliability, and Anomalous Results

   • Explain the purpose of repeating experiments (reliability, anomalous results).

3. Standard Deviation

   • Define standard deviation.

   • Explain what standard deviation reveals about results (variation around the mean).

4. Improving Future Experiments

   • Suggest improvements for a future experiment on exercise and ventilation.

   • Describe a revised experiment and explain the incorporated improvements.
