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…

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

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.
