The student does not clearly state the independent and dependent variables in the research question, which should specify the molar ratio of urea to citric acid as the independent variable and the wavelength of emitted light as the dependent variable. Additionally, the research question lacks a description of the method of analysis, which could be improved by including how measurements will be taken. While the student provides a detailed background theory and justifies the choice of synthesis techniques, there are several areas needing improvement, such as explaining the measurement and control of variables, discussing the rationale behind the number of trials conducted, and clarifying the controlled variables. The methodology is generally well described, but it includes irrelevant information that detracts from clarity. Overall, the student demonstrates awareness of safety, ethical, and environmental issues related to the investigation.
