The student provides a detailed description of the aim of the experiment, which is to examine the effect of salt on the melting of ice and to possibly find the most effective salt that could be used to melt ice. The student also gives relevant background information on the properties of water and the possible effects of salt on ice. The methodology of the investigation is appropriate and focused, including identifying the independent and dependent variables, controlling the variables, and calculating the freezing point depression. The student also explains the theory behind the intermolecular forces in water to help understand the reaction under study. However, the student does not show awareness of safety hazards, ethical concerns, or environmental issues that can arise during the experiment.
