The student does not provide a clear title statement or explicitly state the aim of the investigation, which detracts from the description of the main topic. Additionally, the phrasing of the research question is not precis. While the student does provide relevant background information on sodium sulphate decahydrate, the explanation of the chemistry involved lacks sufficient detail, particularly regarding Le Chatelier's principle. However, the methodology is appropriate and well-focused on answering the research question, outlining the use of calorimetry and addressing the validity of results through controlled variables. The student shows awareness of safety hazards but fails to discuss ethical and environmental concerns adequately.
