The student clearly states the independent variable as the distance from the pivot to the center of the bob and the dependent variable as the period of the pendulum. The research question is well-defined, and the student describes the method of analysis, including measuring the average period of oscillation. A comprehensive background theory related to the physics of a simple pendulum is provided, along with a clear explanation of the measurement techniques and sampling choices. Controlled variables are well-documented, and the student addresses safety, ethical, and environmental considerations effectively. However, there is a lack of discussion regarding the rationale behind the number of trials and the precision of measurements, which could enhance the methodology's robustness. The overall methodology is sufficiently detailed to allow for replication.
