Why do highway trucks pour sand on icy roads in the winter?
I know that salt is used to melt ice and I think that sand is used for the same reason.
If my hypothesis is true, an ice cube with sand on it will melt faster than a bare ice cube.
Materials: ice cubes, sand, watch
Steps: I sprinkled sand on one ice cube and left the other bare. I timed how long it took for each cube to melt.
Data: Each ice cube took one hour to melt.
My hypothesis was wrong, because the sanded ice didn’t melt faster. They must use sand for a different reason.
