The student's method outlined in the exploration is appropriate for the research question, as they used an experimental-based investigation and conducted preliminary research to ensure the suitability of the pH range. The proposed method will allow for the collection of relevant and sufficient data, as the student collected data on radish seed germination with a sufficient sample size and clear measurement of germination rate. Additionally, the student provided clear, step-by-step instructions for setting up the experiment, which would allow for replication. However, the student should have outlined the sampling approach and provided reasoning for its choice, as well as addressed environmental and ethical considerations associated with the exploration. Overall, the method shows careful planning and attention to detail, but there are areas that require further explanation and consideration.
