The student clearly described how the data was obtained and processed, making each procedural step easy to understand. The description of data recording and processing was detailed and precise, with well-annotated tables and graphs that included appropriate units, decimal places, and significant figures. However, the student needed to improve the discussion of uncertainties by clearly showing how each source of uncertainty affected the results. Despite this, nothing in the work undermined the validity of the conclusion, as the student effectively explored the relationship between the mass of potassium nitrate and the saturation temperature. The student conducted relevant data processing that accurately addressed the research question, demonstrating a solid understanding of data variability and reliability.
