The student has identified a focused and detailed topic of investigation, "Examining the Index of Refraction of Water at Different Temperatures," which is clearly explained in the work. The research question, however, lacks the proper format and should focus on the relationship between the chosen independent and dependent variables. The physics concepts related to the topic are well-explained, and the methodology of the investigation is clear, easy to follow, and addresses the research question. The student also demonstrates awareness of safety hazards but should consider discussing ethical and environmental issues relevant to the procedure.
