Salt, Ice and Water

Why is salt put on roads and sidewalks in the winter? Could something else be used instead? The Grade 1/2 class did some experiments to see what common kitchen ingredients melted ice the best. Winners: salt, baking soda, sugar. Losers: flour, cocoa, corn startch. 

The next time we meet we will finish our experiments on salt water and density.
