What could the student do to the potassium chloride to make it conduct electricity?

To make potassium chloride conduct electricity, the student could dissolve it in water to create an electrolyte solution. In this solution, the potassium chloride will split into its ions (K+ and Cl-) which can carry electric current. By immersing two electrodes connected to a power source into the solution, electricity can flow through it via the movement of these ions.
