The student has identified a focused and detailed topic of investigation, which is investigating the resonant frequency in a singing wine glass with varying densities of water. The topic is clearly stated at the beginning of the work, and the student provides a clear breakdown of what will be done in the investigation. The student also demonstrates a good understanding of the physics involved, explaining concepts such as the fundamental frequency of oscillation. The methodology of the investigation is clear, easy to follow, and focused on addressing the research question. The student also shows full awareness of safety, ethical, and environmental issues relevant to the procedure. However, the research question could be improved by including the values of the independent variable and units, as well as using a more detailed question tag to allow for a more in-depth analysis and discussion.
