The student clearly stated the independent and dependent variables in the research question, identifying the independent variable as the concentration of alcalase and the dependent variable as the average rate of ovalbumen degradation. The methodology was well described, detailing the steps and materials used, thereby enabling reproducibility. The student effectively explained the choice of techniques for measuring the variables and discussed the rationale behind the selected concentrations and controlled variables. However, the student did not adequately address ethical and environmental issues, lacking specific details on the absence of ethical concerns and on proper disposal methods for the chemicals used in the investigation. Overall, the student's work demonstrated a solid understanding of the experimental design and methodology.
