The student presents a clear and detailed description of the aim and background information of the experiment, including the definition of alcohols, the determination of standard enthalpy change, and the global relevance of ethanol. The methodology is appropriate to the topic and includes steps to assure the relevancy and validity of the obtained results. However, the student provides limited chemistry-oriented information about alcohols and incorrectly identifies the independent variable as a "mixture of ethanol and gasoline." The student shows full awareness of safety hazards but lacks consideration of ethical and environmental concerns.
