Your 'pendulum counts in-class' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** **
I was a little unsure about the scale factor and the uncertainty but I think I figured it out.

Report one line per observation. Each line should consist the length of the pendulum being observed, the 1-minute count and the scale factor by which your reported length should be multiplied to get the length of the pendulum in centimeters. The three requested quantities should be separated by commas. Each line should therefore consist of three numbers, separated by commas. Don't include any words, units, or other information in any of these lines.
You may report as many lines as possible. Use the space below.
Your data report (start on the next line):
6, 69, 2.54
6, 65, 2.54
12, 51, 2.54
12, 52, 2.54
18, 41, 2.54
18, 39, 2.54
Add your description of how you made your observations. Include an explanation of how much uncertainty there was in each observation, and explain how you arrived at your uncertainty estimate.
Your explanations (start on the next line):
First I measured the string from the middle finger tip to my wrist and then I measured that distance on the ruler and got 6 inches. I then timed my pendulum. There was minor uncertainty since I used a ruler to measure the length of the string and a stopwatch for the 1-minute count. Considering I used measuring instruments for my calculations I have come to the conclusion that I had minor uncertainty.
&#Good responses. Let me know if you have questions. &#
