Procedure 1. Develop a hypothesis regarding one factor you think might affect the period of a pendulum or an oscillating mass on a spring. Potential factors includethe mass, the spring constant, and the length of the pendulum's string. Write down your hypothesis. 2. Design a controlled experiment to test your hypothesis. Take extreme care to keep all factors constant except the variable you are testing. If you plan a pendulum experiment, for example, choose the pendulum's length, and for either experiment, choose the number of oscillations for each time measurement. If you do not have some of the suggested equipment, decide how you could make the measurements using alternative equipment. For example, balls of clay could be substituted for hanging masses, and the pendulum or spring could be attached to a board extending from a bookshelf. If you perform the experiment with a spring, test the greatest mass on the spring to be sure the setup you plan works with the spring extended fully. Your experiment may be set up like the following: 5.4.3 Lab: Simple Harmonic Motion 28 Copyright 2021 Apex Learning Inc. Use of this material is subject to Apex Learning's Terms of Use.

Record your data in thetable below. Record measurements in scientic notation as appropriate. (Note: Dry Lab data below is supplied for an experimental setup using a M 13 //o pendulum.) MIME/m HAG/i0 4. Create two graphs of your data. Both mass and time for 10 oscillations are independent variables, so either can be placed on the X-axis. In the rst graph, place mass on the X-axis. On the second graph, place time for 10 oscillations on the X-axis. The period changes as a result of your independent variable, so it is the dependent variable and should be placed on the yaxis for both graphs. 5. Create a lab report to communicate your findings. The report should include a title page, procedure, data table, graphs, and summary. Be sure that your summary analyzes the findings of your experiment as well as the graph of your results, and that it evaluates the effectiveness of your testing methods. Discuss whether your hypothesis was supported by the data you collected, as well as any modifications you would make if you were to perform the experiment again
