The student stated the independent variable as temperature, provided specific values, and identified the dependent variable as the reaction rate between sodium thiosulfate and hydrochloric acid. The methodology was well articulated, detailing the analytical approach and explaining the rationale for the chosen measurement techniques. The student included a thorough background theory relevant to the investigation, discussing collision theory and the Arrhenius equation. Additionally, controlled variables were identified, and safety issues were addressed, although the student did not adequately discuss ethical and environmental considerations. Overall, the methodology was described in sufficient detail to enable reproducibility, without any irrelevant or repetitive information.
