The student provides a focused and detailed description of the main topic, which is to investigate the effect of different temperature treatments on the pH levels of lime and lemon juice. The methodology used is highly appropriate to the topic, with the heating up/cooling of the juices and measuring their pH. However, the methodology does not include appropriate steps to assure the relevancy and validity of the obtained results, and the student does not show full awareness of safety hazards or ethical concerns that can arise during the experiment.
