This project investigates the swing periods of pendulums of different lengths to identify patterns in their motion. Students will explore how altering the pendulum length affects its period of oscillation.
If the length of the pendulum is increased, then the period of its swing will also increase due to the longer distance it travels.

Cut strings to different lengths and attach a washer to each as a weight.
Fix the other end of the string to a stable point to create a pendulum.
Measure the initial angle of release with a protractor.
Release the pendulum and use the stopwatch to time its swing period.
Record the swing period for each length in the notebook.
Change the string length and repeat steps 3-5.
Analyze the relationship between string length and swing period.
Plot the data on a graph to observe patterns.
Discuss findings and draw conclusions.
Suggest real-world applications of pendulum physics.
Longer pendulums are expected to have longer swing periods, showing a direct relationship between pendulum length and period duration.

Ensure pendulums are securely fixed to prevent them from falling during swings.
Create a visual chart showing pendulum lengths and periods.
Explain how pendulums are used in timekeeping devices.
Demonstrate pendulum motion to the audience.
