The student has provided a focused and detailed topic of investigation, clearly stating the general topic in the form of a research question. The student also provides a breakdown of the topic and what will be done in the investigation. The research question indicates the variables that will be explored, but it could be improved by including the values of the independent variable and changing the question tag for a more detailed analysis. The physics is explained well enough for the reader to understand without rereading, with clear descriptions of concepts and appropriate figures. The methodology of the investigation is clear, easy to follow, and focused on addressing the research question. However, the student should include steps to ensure the relevance and reliability of the collected data, as well as show awareness of safety, ethical, and environmental issues in the risk assessment section.
