The student does not clearly state the independent and dependent variables in the research question, which should be posed as a direct inquiry rather than a descriptive statement. Additionally, the method of analysis is not explicitly described, lacking clarity on how mass and radius will be measured in relation to angular velocity. While the student does provide a detailed background theory and explains the sampling technique applied, there is insufficient discussion on the choice of the number of trials and safety measures related to the investigation. Furthermore, the methodology lacks sufficient detail to allow for reproducibility, as specific information about the digital balance is missing. Overall, while there are some strengths in the background theory and controlled variables, significant improvements are needed in clarity and detail across several aspects of the investigation.
