This is an excerpt from the paper...
Part I - Comparing conductivity of ionic vs covalent substances100mL distilled water was placed in a very clean glass, 100mL tap water was placed in another clean glass, and 100mL purified drinking water was placed in a third glass. All three types of water were tested by carefully placing the exposed metal portion of the electrodes of the conductivity apparatus in the solution to be tested, keeping the liquid level below the plastic coating on the wires. The ammeter reading was recorded for each sample tested. A new sample of distilled water was obtained, a pinch of salt added, and the water stirred until all the salt dissolved. The conductivity of the salt solutions was tested. The electrodes were rinsed with distilled water between tests. Another pinch of salt was added and dissolved, the conductivity tested and the appearance of the solution noted. The experiment was repeated using sugar in place of the salt until four pinches of sugar had been added. The conductivity was measured after each pinch of sugar was dissolved
