The student clearly stated the independent and dependent variables in the research question, identifying the molar concentration ratio of zinc sulfate and copper(II) sulfate as the independent variable and the electric potential of the Daniell cell as the dependent variable. The research question outlined the analytical method and explored how concentration ratios affect the cell's electric potential in a systematic manner. A thorough background theory section was included, effectively connecting key concepts relevant to the investigation. However, the student did not clearly explain the techniques used to measure the dependent variable, providing insufficient detail on the equipment and procedures necessary for accurate measurements. Additionally, while the student adequately addressed controlled variables, ethical considerations, and environmental issues, safety issues were only partially addressed, indicating a need for greater specificity in identifying potential hazards.
