The student has identified a focused and detailed topic of investigation, clearly stating the purpose of the IA. The physics behind the topic is explained well enough for the reader to understand without difficulty. The methodology of the investigation is clear, easy to follow, and focused on addressing the research question. The student also demonstrates awareness of safety, ethical, and environmental issues relevant to the procedure. However, the research question could be further improved by specifying the range of values for the independent variable and using a more detailed question tag. Additionally, the methodology should include steps to assure the relevance and reliability of the collected data by providing specific methods and reasons for controlling each variable.
