The student identifies a focused investigation into the effects of fine salt on the specific heat capacity of water, as evidenced by the clear aim and research question. However, the research question could be more specific by including detailed values for the independent variable and the method for measuring the dependent variable. The physics is explained well, with clear definitions and logical reasoning, and the methodology is presented in a structured format, with clear steps and safety considerations. The student also demonstrates awareness of safety hazards and ethical issues relevant to the procedure. However, the discussion lacks detailed steps on how environmental resources will be conserved or disposed of responsibly, which could be addressed to strengthen the environmental aspect of the methodology.
