The student outlined the topic of their study clearly at the beginning of the essay, indicating its aim and focus on the effect of simmering kidney beans on their iron content. The investigation was relevant to IB Chemistry because it examined food chemistry and used spectrophotometry, a method covered in the syllabus. The student established a clear context by providing background information on iron's role in health and the chemical basis for the experiment. However, the focus on specific chemical mechanisms would be strengthened. The research question was well-defined and relevant to chemistry, and the methodology section was detailed enough for replication, demonstrating a thorough approach to data collection and analysis.
