different salts on melting points. Four patches of ice of equal size are
iS salt is poured on each, one receives table salt (NaCI), one receives Calcium Chloride (CaCl2),
one receives Potassium Carbonate (KCO3)
The student measures the volume of ice
and the fourth receives inert sand instead. Each patch receives an equal amount of salt or sand. The s
