Project Summary

Our project was to find out what substance makes ice melt the fastest. To test this we put three similarly sized ice cubes in four seperate bowls. In one bowl we covered the ice with a teaspoon of salt, in another a teaspon of sugar and in another a teaspoon of sand. The fourth bowl was only ice and was our control. Then we put the bowls in the refrigerator. This was so that the substances could do the melting and it wouldn't be the temperature.

Our prediction was that the salt would melt the ice fastest, because we know they put salt on roads, driveways and sidewalks to melt ice in the winter.

After about 90 mins we took the bowls out of the refrigerator. We could visibly see that the salt melted the ice the most, the bowl was almost all water and barely any ice left. The bowl with sand and the control seemed to have the most ice. To measure it precisely we poured the water from the bowls in to a measuring cylinder and saw how many millileters of water there was. Our guess was correct, the salt produced the most water, then sugar and then sand. The sand melted the water only a little bit more then the control, by just one milliliter!

We learned that soluble substances, things that dissolve in water, will melt ice faster then things like sand which to not dissolve. We also learned that the salt actually changes the temperature at which water freezes. It makes water freeze at a temperature below 32 degrees. This is why they will put out salt before the snow or ice comes.

We hope you enjoyed our project.
