The student did not justify their choice of topic in terms of personal significance, interest, or curiosity. They should include a rationale at the beginning of their work, explaining why they chose this topic. Additionally, the student should provide evidence of personal input and initiative in the design, implementation, or presentation of the investigation. This can be done by including self-designed diagrams or models of the experimental setup, as well as a description of a preliminary trial. By incorporating these elements, the student will demonstrate their active involvement in the study.
