The student clearly describes how the data was obtained and processed, making each procedural step easily understood, particularly in measuring the final dry mass of Viola odorata plants. However, the description of data recording and processing lacks detail and precision, as the figure titles and graph labels need improvement for clarity. Additionally, the student does not adequately consider the impact of uncertainties on the data and results, which could be addressed by calculating percentage uncertainty. While the student's investigation is well-structured and valid, relevant data processing is insufficiently detailed, as the average calculations and measures of variability should be explicitly stated and demonstrated.
