A teacher sets up a demonstration in class with two containers, one with fresh water and the other with salt water. she adds one ice cube to each container and begins the timer to see which ice cube will melt the fastest. the students are asked to predict which container will melt the ice the fastest. most of them predict that the salt water will melt the ice the fastest, but the freshwater has the faster time. how is the ice melting in both systems? what would the students expect to see if the ice had food coloring in it and was allowed sit for some time? design an investigation to determine why freshwater melts ice faster than salt water. be sure to include all steps of the scientific process.
