The student clearly stated the independent and dependent variables in the research question, identifying the cooking temperature of bitter gourd as the independent variable and the absorbance of charantin as the dependent variable. The methodology was well described, including the analysis method using a spectrophotometer and a detailed background theory that connected theoretical principles to the experimental process. The student effectively discussed controlled variables and their management, as well as the rationale behind the chosen sampling techniques and the number of trials, enhancing the reliability of the results. However, there was insufficient clarity regarding the ethical and environmental issues associated with the investigation, which required further elaboration. Overall, the methodology was sufficiently detailed to allow reproducibility and was free of irrelevant information.
