All subcriterion are fulfilled and the maximum number of points are awarded for this criterion. The student's essay accurately reflects the aim of the investigation through a clear and concise title. The title is presented as a statement and is not the same as the research question, which aligns with the requirements. In the introduction, the student effectively outlines the area of research, the purpose, and the focus of the essay, establishing the context of the research question. The relevant physics principles are qualitatively described with appropriate diagrams, and a formal development of the theory follows later in the essay. The research question is centered purely on physics as a science, and the student effectively demonstrates the choice of methodology and materials that address the research question. Additionally, the student presents the theory behind the experiment by referring to appropriate and reliable sources and considers the uncertainties and limitations of techniques and apparatus for data collection.
