The student clearly states the independent variable as the height of the ramp and the dependent variable as the time it takes for a cylinder to roll down, establishing a direct relationship in the research question. However, the research question lacks a specification of the method of analysis, which could be improved by including how the dependent variable will be assessed. The background theory section is well-developed, explaining relevant concepts such as potential and kinetic energy, and the student effectively describes the choice of the sampling technique. Nonetheless, the student does not justify the number of trials conducted, nor do they address safety, ethical, or environmental issues associated with the investigation. Additionally, there is a need for more detail in the methodology to ensure reproducibility, specifically regarding the measurement tools used.
