The student presents a focused and detailed description of the main topic, clearly stating the investigation's purpose. However, the research question lacks precision in wording and units for the dependent variable. The background information provided is not fully focused on the relevant chemistry behind the experiment, and the explanation of the chemistry is also lacking. On the positive side, the chosen methodology is highly appropriate, focused, and includes steps to assure the relevancy and validity of the results. The student also demonstrates awareness of safety hazards and ethical concerns, but needs to address environmental issues more comprehensively.
