The student clearly states the independent variable as the increasing tension in the string and the dependent variable as the fundamental frequency produced. However, the research question lacks a description of the method of analysis, which should include details on how the fundamental frequency will be measured. While the background theory is well-developed and relevant concepts are effectively explained, the student does not adequately justify the choice of tension values or discuss the number of trials and precision of measurements. Additionally, while the student addresses safety, ethical, and environmental issues, the methodology lacks detailed procedural steps necessary for replication. Overall, while there are strengths in certain areas, significant improvements are needed in the explanation and justification of the experimental design.
