The student clearly stated the independent variable as the amount of plastic mesh used and the dependent variable as the rate of photocatalyzed degradation of Eosin-Y, demonstrating a relationship between the two. However, the research question lacked a specified method of analysis, which should have been included for clarity. The student provided a comprehensive background theory relevant to the research question and explained the choice of sampling technique, including a preliminary experiment. While the methodology was generally well-explained, it required more specific details, such as the exact mass of materials used and the procedure steps, to ensure reproducibility. The student effectively identified and addressed safety, ethical, and environmental issues associated with the investigation.
