The student provided a focused and detailed description of the main topic, clearly stating the research question regarding the effect of varying pH levels on the rate of photosynthesis in Elodea. The methodology was appropriate and effectively addressed the research question, including control variables and systematic procedures that ensure valid results. However, the student did not fully meet the requirements for providing relevant background information, as well as addressing ethical and environmental concerns related to the experiment. While safety hazards were identified and precautions were outlined, further elaboration on ethical and environmental implications was necessary to demonstrate full awareness in these areas.
