The student did not clearly state the independent and dependent variables in the research question, nor did the research question specify the method of analysis to be conducted. However, the student provided a relevant background theory and effectively explained the choice of techniques used for measurement, including justifications for using calorimetry. The methodology was described in detail, with clear steps and controlled variables identified, ensuring reproducibility. Additionally, the student addressed safety, ethical, and environmental issues associated with the investigation, which reflected a comprehensive approach to the experimental design. Overall, while there were areas for improvement in the clarity of the research question, the methodology and supporting details were well articulated.
