The student provides a focused and detailed description of the main topic in the body of the Introduction, clearly stating and explaining the topic of the investigation. The student also includes background information that is relevant and focused, providing a good explanation of the key concepts necessary for understanding the experiment. The chemistry of the experiment is very clearly explained, including the functioning of a Daniell cell, oxidation-reduction reactions, cell potential, and the Le Chatelier principle. The methodology of the investigation is highly appropriate to the topic, as the student constructs a Daniell cell and records the cell's potential in varying concentrations of the CuSO4 solution. The student also shows full awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment.
