The student accurately and clearly reflects the aim of the investigation in the title of the essay, which is presented as a statement of appropriate length. Although the title is not the same as the research question, the research question should be a question, not a statement. the student effectively outlines the area of research, purpose, and focus of the essay in the introduction. Additionally, the relevant physics principles are identified early in the essay, and a formal development of the theory relevant to the research question follows later on. The student also demonstrates that their chosen methods and materials effectively address the research question by correctly identifying variables and providing a table with controlled variables. However, the essay lacks citations for the explained physics theory and needs to state the uncertainties of the apparatus used in data collection.
