The student provides a focused and detailed description of the electroplating process, clearly articulating the research question regarding the influence of varying voltage levels on the mass change of copper cathode and zinc anode. Background information is relevant, covering principles of electrolysis and redox reactions, while the methodology is appropriate and specifically designed to address the research question, ensuring reliability and validity of results through controlled variables and consistent conditions. The student demonstrates awareness of ethical and environmental issues, providing Material Safety Data Sheets for the chemicals used and emphasizing proper handling and disposal procedures. However, the student does not fully address safety hazards, as one chemical (copper sulfate) is omitted from the safety considerations.
