The student clearly states the independent and dependent variables in the research question, identifying the molar concentrations of H2SO4 as the independent variable and the growth of mung beans as the dependent variable. The methodology is well-described, including the analysis method of measuring growth by recording mass over 48 hours. The student provides a detailed background theory relevant to the investigation and explains the choice of techniques used for measuring variables, ensuring the methodology is reproducible. However, there is a lack of discussion regarding the choice of the number of trials conducted, which should be addressed for a more comprehensive understanding. The student effectively identifies and addresses safety, ethical, and environmental issues associated with the investigation, demonstrating a responsible approach to the research.
