What makes ice melt faster salt sugar or sand science fair project?

Salt will always melt ice quicker than both of them. This is because in the same amount or volume, there are more molecules of salt than sugar or baking soda due to the chemical make-up. Salt, baking soda, and sugar will all act to lower the freezing point of the ice, making it melt quicker than the untouched ice cube.
