The student's exploration method is well-suited to the research question, as it aims to investigate the effect of NaCl concentration on the germination of Oryza sativa seeds. The proposed method includes a range of NaCl concentrations and a large sample size, ensuring that the data collected will be both relevant and statistically significant. Furthermore, the method is described in sufficient detail for replication, with clear steps and materials outlined. The sampling approach is also clearly outlined, with 250 seeds evenly distributed across 25 Petri dishes, and the reasoning for this approach is well-justified based on availability and previous studies. Additionally, the student identified and described potential safety risks associated with the method, demonstrating an awareness of safety considerations. However, the student did not explicitly outline any environmental considerations, which could have been addressed separately. Overall, the exploration method demonstrates thorough planning and consideration of key factors.
