The student's method outlined in the exploration is appropriate to the posed research question, as it includes the range of pH used in the investigation and the measurement to answer the research question. However, the proposed method did not allow for sufficient replication, as only three plants were used as trials. The method is described in sufficient detail to allow for replication, with clear steps and differentiation of treatment, but it lacks an outline of the sampling approach and fails to list any risks, environmental considerations, or ethical considerations associated with the exploration. The student should address these shortcomings to ensure a more comprehensive and replicable exploration.
