The student identifies a focused and detailed topic of investigation in the introduction and supports it with a relevant and fully focused research question. The physics behind the topic is explained well enough for the reader to understand it without the need for rereading. The methodology of the investigation is focused on addressing the research question and correctly identifies the independent and dependent variables. However, the methodology lacks a proper description of the experimental procedure and the investigated variables, as well as steps to assure the relevance and reliability of the collected data. Additionally, the student did not show full awareness of safety hazards, ethical and environmental issues relevant to the procedure.
