The student had clearly stated the independent variable, agarose gel concentration, and the dependent variable, the distance traveled by Bacteriophage λ cI857 Sam7 DNA bands, in the research question. However, the research question had lacked a description of the method of analysis used, which should have been included for clarity. The student had provided a detailed explanation of the techniques used for measurement and the rationale behind the choice of agarose concentrations, but had failed to discuss the number of trials or the precision of measurements adequately. The student had effectively identified and addressed safety, ethical, and environmental issues related to the investigation, and had presented a sufficiently detailed methodology that allowed for reproducibility without irrelevant information.
