The student provided a clear and focused description of fermentation as the main topic, outlining its types, the biochemical process in Saccharomyces cerevisiae, and its relevance to the investigation. They also stated the research question at the end of the paragraph, tied its relevance to the topic of fermentation and the experimental approach, and clearly identified the variables in relation to the experimental design. Additionally, the student included relevant background information on the fermentation process, anaerobic conditions, and how CO₂ production related to fermentation, ensuring the information was directly applicable to the investigation. The biology was explained with clarity, using chemical equations and steps to aid comprehension. However, the student should have explicitly stated a null hypothesis, which would predict no effect of temperature on the rate of fermentation. Nevertheless, the methodology was appropriately designed to investigate the effect of temperature on the rate of fermentation, and the student demonstrated awareness of safety hazards, ethical concerns, and environmental issues related to the experiment.
