The student provides relevant and focused background information on the digestion of lipids in the human digestive system, the role of lipase in lipid digestion, and the process of hydrolysis. This information sets the context for the study and helps the reader understand the significance of investigating the effect of temperature on the rate of hydrolysis of lipids in milk. The biology is explained thoroughly and clearly, allowing the reader to fully and easily understand it without the need for rereading. The methodology of the investigation is highly appropriate to the topic of studying the effect of temperature on the rate of hydrolysis of lipids in milk, and each step of the experimental procedure is designed to directly address the research question. The methodology also includes appropriate steps to ensure the relevance and validity of the obtained results, such as the use of repeats, qualitative observations, and statistical analysis. However, the student should have included a title at the beginning of the document, and the temperature range studied in the experiment should have been included in the research question. Additionally, the student did not state the hypothesis in a correct way and should have stated a null and an alternative hypothesis.
