Design your own experiment to test how your body changes during exercise. You may develop this new experiment to test the changes in heart rate, breathing rate, or any other parameter occurring during exercise. First, formulate a question to answer through scientific investigation. Keep in mind that you should be able to answer your question with measurable data. Write your question here.

Write your plan for the experiment. Note the dependent and independent variables. To ensure that your results test only the dependent variable, consider how you will control outside factors.
