4th/5th Class Investigate the Impact of Salt on Ice

In this experiment we investigated the impact of salt on ice. We placed ice cubes in a tin can, laid the string on the ice, added salt and after approximately one minute we pulled the string out of the water with all the ice cubes attached.

When salt is sprinkled over the ice, it lowers the ice’s freezing point and causes it to melt. Water around the ice forms and then the string sinks into the ice.
