The student clearly states the independent variable as the temperature of the metal wire and the dependent variable as its electrical resistivity in the research question. However, the student fails to describe the method of analysis for measuring resistivity, which detracts from clarity. While a background theory section is included, explaining the relationship between temperature and electrical resistivity, the student does not adequately justify the choice of temperature range and increments used in the experiment. Controlled variables are identified and explained, and safety issues are addressed thoroughly, but ethical and environmental concerns are not sufficiently justified or discussed. Overall, the methodology is described in sufficient detail for reproducibility and is free from irrelevant information.
