I set up the experiment by attaching each washer to a string, 1 washer at a time. I then suspended the washers and dropped them from a set height and timed the amount of time it took for the washer to stop moving. I then recorded the data in the data table.
- During the experiment I found that the lightest washer stopped swinging first. This was the result that I expected.
- The experiment well. I didn't run into any difficulties. This would be a lab that my students could do with ease. I would not expect them to encounter any difficulties.
- I would not make any modifications at this point in time.
- In completing this activity, I would want my students to understand the idea of a pendulum and how it works. I would also like them to explore force and motion and how these are at work in this situation. I would also like for them to investigate the idea of perpetual motion and why the pendulum stops when it does.
