The student has successfully identified a focused and detailed topic of investigation, which is the relationship between the distance of a mass from the center of the pendulum and the period of oscillation of a bifilar pendulum. The research question, however, lacks clarity in specifying the method of measurement for the period of oscillation, and the inclusion of such detail would enhance precision. The explanation of physics could be improved by including visual aids to clarify the concepts being discussed. The methodology is clear and well-structured, outlining variables, controlled variables, apparatus, setup, and the step-by-step procedure. However, there is a need for a more detailed explanation of the independent and dependent variables, as well as the method used to measure the period of oscillation. The student has demonstrated a full awareness of safety, ethical, and environmental considerations relevant to the procedure.
