The student provides a clear and focused description of the aim of the experiment, which is to investigate the effect of ascorbic acid in varying concentrations on the growth of plants to potentially find more natural sources of said acid. The student also provides relevant background information on the Pisum sativum plant that provides the context for this investigation. The methodology of the investigation is highly appropriate to the topic, as spraying newly-germinated seedlings with the desired concentration of ascorbic acid is an appropriate method of investigating its effect on the plants. The student also shows full awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment. However, the background information section lacks biological detail of the concepts surrounding the relationship of vitamin C and plants, and a null hypothesis is not included.
