Question - What I want to learn from this topic?
Research- Find information about the topic.
Materials-List the materials that you will need to test.
Hypothesis- (Predict) If...................., then...............
Example: If I use nylon string, then the frequency for the pendulum bob will be 27.
Procedures-(Directions) List all the steps you will do throughout your experiment.
1. Attach the nylon string to the large washer
2. Tape the angle protractor to the edge of the table. Place the end of the string at 0 degree.
3. Set timer for 30 seconds.
4. Pull the string with the washer at starting point: 90 degrees (angle).
5. As soon as you let go of the string, start the timer.
6. Count the frequency (number of swings-forward and back)
7. When 30 seconds is up, write your data on the data chart.
8 Do #4-7 for three trials (tries).
9. Calculate total and average.
Data Table (Observations- you will test and record data in your table)
Results
Conclusion- Explain your results (what happened?) and be sure to compare true answer with your hypothesis to see if they match or unmatch.
