Title: Finding the Value of 'g' Using a Simple Pendulum
Introduction:
In this physics project, high school students will investigate the acceleration due to gravity ('g') using a simple pendulum. Through research, a combination of real and virtual experiments, data analysis, and creating trifold presentations, students will gain a deeper understanding of the factors affecting the period of a pendulum and how it relates to 'g'. This project is designed to be performed in groups to encourage collaboration and teamwork.
Materials:
Computer or laptop with internet access
Virtual simulation software (e.g., PhET simulations)
Graphing software (e.g., Microsoft Excel or Google Sheets)
Printer (for creating trifold posters)
Poster board or paper for trifold posters
Writing materials (pens, markers, etc.)
String or thread
Weight (e.g., a small mass or a washer)
Ruler or measuring tape
Stopwatch or timer
Safety goggles
Procedure:
Research: a. Begin by researching the concept of a simple pendulum, including its definition, properties, and the factors affecting its motion. b. Explore the mathematical relationship between the period of a pendulum and the length of the pendulum. c. Take notes and gather relevant information to support your understanding of the topic.
Experimental Setup: a. Set up a pendulum by attaching a weight to a string or thread. b. Measure the length of the pendulum from the point of suspension to the center of the weight. c. Ensure the pendulum swings freely without any obstructions. d. Put on safety goggles to protect your eyes during the experiment.
Real Experiment: Measuring the Period a. Release the pendulum from a small angle (less than 15 degrees) and start the stopwatch or timer. b. Count the number of swings for a specific time interval (e.g., 10 swings in 30 seconds) and record the time. c. Repeat the measurement multiple times and calculate the average period for each pendulum length. d. Record the length of the pendulum and the corresponding period of oscillation in a data sheet.
Virtual Experiment: Varying the Length a. Use virtual simulation software to perform experiments and observe the behavior of a simple pendulum. b. Vary the length of the pendulum while keeping other variables constant. c. Record the period of oscillation for each length and gather the data for analysis. d. Take screenshots or record videos of the simulations to include in your project presentation.

Data Analysis: a. Use graphing software to plot a graph of the period squared (T^2) against the length of the pendulum (L). b. Analyze the graph to determine the relationship between the period squared and the length of the pendulum. c. Use the relationship to calculate the value of 'g' by comparing the slope of the graph to the theoretical value of 4π^2/g. d. Calculate the average value of 'g' based on multiple measurements from both the real and virtual experiments.
Presentation: a. Create trifold posters to showcase your project findings. b. Include sections for introduction, research, experimental setup, data collection, data analysis, and conclusion. c. Use visual aids such as diagrams, graphs, and images to enhance the presentation. d. Write clear and concise explanations for each section, highlighting key points and observations.
Group Discussion: a. Present your project to the class, explaining your research, experiments, data analysis, and conclusions. b. Engage in a group discussion to exchange ideas and gather feedback from classmates. c. Answer any questions or challenges raised by your peers or the teacher.
Conclusion:
By conducting a combination of real and virtual experiments, collecting data, analyzing results, and creating trifold presentations, high school students can determine the value of 'g' using a simple pendulum. This project encourages collaboration, critical thinking, and practical application of physics principles.
