Ice and Salt Experiment!

Today for science we had an ice and salt experiment the experiment itself was about putting an ice in cold water and placing a match gently on top of it then adding some salt. That will somehow create the match sticking onto the ice so you can just pick up the matchstick its self with the ice cube dangling off it.  I was in a group of three with Keghan and Teyha, the science behind his experiment is that the ice cube and water is state of forces being balanced. It releases a lot of energy in the form of heat, that means everything gets colder even the ice cube. So under the ice cube where there is no salt the ice refreezing and freezes the matchstick as well so the matchstick sticks to the ice.

My team was not so lucky we got the job but there was evidence as soon as we turned off the video succeeded but you couldn't see that we had so much trouble. Why? It's because we probably added too much or too less salt also we had to keep grabbing more ice cubes. After we finished we washed the beaker and there was a load of salt in there so we knew we used way to much salt. We took some photos so here they are.

Why do we sprinkle salt on icy roads? It helps the ice on the road to melt quicker so we drive on it and not slip and accidents.
