The student clearly describes how the data was obtained and processed, providing a detailed methodology that includes raw data and qualitative observations, which enhances understanding. However, the description of data recording and processing lacks precision, as not all values are presented with consistent significant figures. Additionally, the student does not include considerations of uncertainties, which is important for assessing the reliability of the results. While the work maintains validity in its conclusions and presents a systematic methodology, relevant data processing is insufficient, as the student fails to show sample calculations for average mass loss, which would clarify the connection between raw data and results.
