The student provides a focused and detailed description of the main topic at the beginning of the work, including a title and an aim statement. However, the research question is not focused and lacks clarity. The student should have listed the exact variables investigated and included the values of temperature and pH in the question. The background information provided by the student is relevant and focused, covering the plant studied, germination conditions, acid rain occurrence, and factors contributing to pollution. However, the biological explanation could have been more comprehensive, including discussions on plant biology, seed structure, growth, photosynthesis, and appropriate diagrams. The student does not include a null and alternative hypothesis, which should have been stated before the methodology. The methodology is highly appropriate to the topic, but the student should have included the values of temperature and pH in the buffers. The methodology includes steps to assure the relevancy and validity of the results, and the student shows awareness of safety hazards. However, there is no mention of ethical concerns, and if there are none, the student should state so and clarify that no living organisms were involved in the investigation.
