Part 1
When designing and testing your pendulum, make sure you note as many variables as possible and their type!!
1. Construct your simple pendulum by using a light string, a small bob (preferably something uniform and not strangely shaped), a protractor, and a measuring device for length. To measure time, use your smart phone. Practice using it.
Tips!! When releasing the bob, make sure it is almost exactly on the right angle. Also, your bob SHOULD NOT BE SPINNING on its OWN axis while the oscillations occur. If it does, this is NOT a valid experiment.
2. Enlist a family member or friend (if possible) to help with the data collection. You will need (several) trials to get an average period of a single oscillation.
3. Careful data collection must be made to get reasonable results. Your grade will be based on the quality of these results.
4. Follow the directions in the manual very carefully. Your TA may hold a class session to go over many of the particulars.
Part II
For the second activity, you will upload an MP4 file of you collecting data. You don’t have to show yourself. But, you need to show how data was collected and what with. Please describe verbally with as much detail.
Part III
Follow the directions for the discussion board at the end. Note the variables (and the type) for your classmates.
