No, you are supposed to measure it for your science fair project.
The purpose would be "why do you want to know which makes ice melt faster?"
The reason is that street/road crews will put down salt, sand, or both on icy roads. Why would they do that? Maybe you should measure how slippery an icy surface is after it has salt applied, sand applied, or both applied.

a answer of salt in water has a decrease freezing element than organic water. So if that is less than the freezing element of water yet above the answer's freezing element, the answer will melt fairly of most suitable frozen. Sand improves traction at the same time as walking or making use of over ice and snow, despite the indisputable fact that it doesn't produce a answer because sand doesn't dissolve in water.

salt. Sand will actually protect the ice from the sun, and keep it cold. Sand is effective in keeping the ice from being too slippery but does not melt it much.

Salt, because it lowers the freezing point of water, while sand does not affect it.
