The student provides a focused and detailed description of the aim of the experiment, which is to investigate the effect of tea solutions and their potassium content on the rate of germination of Vigna radiata seeds. The research question is not explicitly stated, but the methodology employed is highly appropriate to the topic and focused on answering the research question. The student also shows full awareness of safety, ethical, and environmental concerns that can arise during the experiment. However, the background information provided lacks detail and leaves some essential biological concepts unexplained. The null and alternative hypotheses are stated and explained appropriately, and the methodology includes appropriate steps to assure the relevancy and validity of the obtained results.
