1. Pendulum Lab  Refer to Swing Time on pg. 21.  Question: Choose one of the following:  Does the swing of a pendulum take longer for an object of greater mass?  Does the swing of a pendulum take longer if the string is longer?  Hypothesis: If…then…

2. Experiment:  MV:  RV:  CV: (at least 3 important ones)  Materials:  Procedure: (numbered list) – don’t forget multiple trials; quantitative data; start each with a verb  Apparatus setup picture or drawing  Data Table

3. Effect of Length of String on Pendulum Swing Time Length of String (cm) Time for One Swing (sec.)Swing TIme Ave. (sec.) Trial 1Trial 2Trial 3 20 30 40 50 60

4. Effect of Mass on Pendulum Swing Time Mass (washers) Time for One Swing (sec.)Swing TIme Ave. (sec.) Trial 1Trial 2Trial 3 1 2 3 4 5

5. Analysis:  Average data – round to nearest tenth.  Make a line graph – use graph paper; put the MV on the X-axis (horizontal) and the RV on the Y-axis (vertical). Include labels and scales (use equal intervals) on each axis. Include a title. Conclusion: Does the data support the hypothesis? Answer the question using the data. Problems. Extension.
