The student provides a focused and detailed description of the main topic by clearly presenting the research question about the effects of temperature and time on iodine content in iodized salt. The introduction connects the investigation to contemporary issues, such as food safety concerns stemming from the Fukushima wastewater release. Additionally, the background information explains the significance of iodine, its dietary sources, and the method of iodometric titration, establishing a foundation for the investigation. The methodology of the investigation is highly appropriate to the topic, as iodometric titration is employed to measure the effect of temperature and time on iodine content in iodized salt. The student outlines independent variables and exposure times essential for the investigation, ensuring the methodology is focused on answering the research question. Additionally, the methodology includes appropriate steps to assure the relevancy and validity of the obtained results, such as specifying controlled variables and including uncertainties in the apparatus list. However, the student does not show full awareness of ethical concerns. The work lacks an in-depth exploration of the chemistry behind the study and the research question should have been rephrased for a more focused approach.
