Salt, Salt, Salt!

Overview

Objectives The objective for this project is to see if there is an alternative to the road salt that they use to thaw the snow on mountains that will melt ice/salt faster. Methods Tablespoon to measure the salt, 6 different salts, stopwatch, camera. Used stopwatch and camera to record the times of my experiments into my journal. Results The results that I got was that table salt melted the ice the fastest in 29 minutes and 12 seconds. While I thought that rock salt would melt the ice the fastest with the time of 36 minutes and 43 seconds. Conclusions My hypothesis was incorrect because I thought that rock salt was going to melt ice the fastest while table salt melted ice the fastest. Rock salt had a time of 43.08 and 36.43 minutes while table salt had a time of 29.12 and 30.30 minutes. I got these results because I thought that because rock salt doesn t have all the added chemicals that table salt has but it helped table salt melt the ice faster. A variable that could have affected my results was putting not enough or more than enough salt onto the measuring spoon. An improvement that I can make next time I do this experiment is not holding the ice when I put it into the cup so that the heat of my hands doesn t make the ice start to melt before I put it into the cup.
