The student has identified a focused and detailed topic of investigation, clearly stating the effect of salt concentration on the specific heat of water. The research question, although relevant, could be improved by including the values and units of the independent variable and changing the question tag to allow for a more detailed analysis. The student demonstrates a good understanding of the physics concepts related to the topic and could enhance the explanation by including visual aids. The methodology is clear and easy to follow, addressing the research question and ensuring the relevance and reliability of the collected data. However, the student should include statements regarding ethical and environmental issues, if applicable, in the same section where safety issues are discussed.
