The student clearly states the independent variable as the inclination angle and the dependent variable as the acceleration of a block sliding on an incline. However, the research question lacks specificity regarding the method of analysis, which should include details on how the acceleration will be measured. The student does provide a thorough background theory and a clear explanation of the choice of techniques for measuring the variables, as well as controlled variables and their management. Nonetheless, there are several areas for improvement, including discussing the number of trials, addressing safety, ethical, and environmental issues, and providing a more detailed methodology to ensure reproducibility. Overall, while the student demonstrates a solid understanding of the investigation, they must address these shortcomings for a more comprehensive approach.
