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.
** **
sorry, I think I got it this time.

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.
The first pendulum was the length of my middle finger to my wrist, the count was 70 oscillations .
The second pendulum was doubled the first and the count was 50 oscillations.
The third pendulum was doubled the second and the count was 35 oscillations.
Your data report (start on the next line):
19, 70, 3.7
38, 50, 1.3
76, 35, .46
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):
I took the pendulum that was as long as from my middle finger tip to my wrist and started swinging it, and started a stopwatch and stopped after a minute. My uncertainty is to the best of my knowledge around a second clock wise, and a half of a tick pendulum wise.
I took the pendulum I had and doubled the length and did the same as with the last. My uncertainty was around a second and a quarter of a tick because the ticks were more definable.
I took the pendulum that I had from the last observation and doubled it and repeated the same thing with the stop watch. Uncertainty is near a second and less than a quarter of a tick because the length of the tick made it easier to define.
Thanks. The data look good.
