Part 3: Testing a New Hypothesis
Test a new hypothesis. You may use your previous data. The prediction should be quantitative for the specific conditions of the experiment (for example, for a particular value of your height; the minimum size of the mirror is). In your prediction, you used the results of measured values that are subject to uncertainty. Estimate the absolute value for this uncertainty. Perform the experiment by covering the mirror with paper or by using a marker so that you can see your entire body (or your entire head). Record the results of the measurement, including uncertainties. Compare these experimental values with your predictions. Are they consistent with each other within your uncertainty? If your measurements and predictions are inconsistent, what are the possible reasons? Could assumptions affect your result? Discuss it with your instructor.
