The student does not clearly describe how the data was obtained and processed, lacking a detailed and structured account of the experimental procedure. It is recommended that the student provide step-by-step instructions for the experiment, including specifics on measurement timing and data recording. However, the description of data recording and processing is detailed and precise, with appropriately annotated tables and graphs that consistently apply correct units, decimal places, and significant figures. The student effectively considers the impact of uncertainties on the data and results, demonstrating an understanding of how uncertainties influence measurements. Additionally, there is nothing in the work that would hinder the validity of the conclusion, and the student conducts relevant data processing that accurately addresses the research question.
