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 appropriate annotations, units, and significant figures throughout the work. However, the student did not adequately address the impact of uncertainties on the data and results, which would enhance the analysis. Despite this, there were no major omissions or inaccuracies that would undermine the validity of the conclusions, as the student successfully supported the hypothesis regarding caffeine extraction. Additionally, relevant data processing was conducted to accurately address the research question, demonstrating a solid understanding of the underlying theoretical concepts.
