The student has identified a focused and detailed topic for the investigation, specifically exploring the effect of temperature on the terminal velocity of a ball in a viscous fluid. The research question is relevant, specific, and fully focused on the investigation's topic, providing a clear direction for the experiment. The explanation of the physics involved, including Stoke's Law and the forces acting on the sphere in a viscous fluid, is clear and coherent. However, the methodology of the investigation could be improved by providing a more specific description of the experimental procedure, including all specific values of glycerol temperature for which the experiment was supposed to be repeated. Despite this, the methodology is well-focused on addressing the research question and includes steps to assure the relevance and reliability of the collected data, such as conducting multiple trials at each temperature and controlling variables. The student also shows full awareness of safety hazards, ethical issues, and environmental issues relevant to the procedure.
