The student provides a focused and detailed description of the main topic, with a contextualized introduction and an explanation of the principles governing concentration cells and the Nernst equation. The background information is relevant and focused, including an explanation of concentration cells, redox reactions, and the Nernst equation, supported by credible sources. The chemistry is explained well enough for the reader to fully understand, with detailed explanations of the concentration cell concept, roles of the anode and cathode, and the Nernst equation. The methodology is highly appropriate to the topic, outlining the apparatus, step-by-step procedure, and control variables for consistency. However, the methodology lacks appropriate steps to assure the relevancy and validity of the obtained results, as the control variables section is vague and incomplete. The student demonstrates full awareness of safety hazards and environmental issues related to the experiment, but there is no mention of ethical concerns, which should have been addressed explicitly.
