The student clearly states the independent and dependent variables in the research question, identifying the launch angles and the horizontal range of the ball. However, the research question lacks a description of the method of analysis, which could enhance clarity. The student provides a thorough background theory relevant to the investigation and effectively names and controls various variables, addressing safety, ethical, and environmental issues associated with the experiment. Nevertheless, there are gaps in the explanation of the choice of techniques, sampling methods, and justification for the number of trials, which need to be clarified for a more comprehensive methodology. Overall, the methodology is described sufficiently for reproducibility, with no irrelevant information included.
