Learning Experience: Identify the conclusion of the situation below. Allan is wondering why his mother always adds a small amount of salt to the water every time she boils the water. To know the effect of salt to the water, Allan performed an experiment. In set-up 1, Allan boils 1 liter of water. Set-up 2, he boils the same amount of water in set-up 1 but this time he adds a pinch of salt. Set-up 3 has the same procedure in set-up 2 but this time he adds ½ teaspoon of salt and in set-up 4, the same set-up like the previous set-up but he adds 1 teaspoon of salt. Allan tabulated all the data from the experiment. (10 pts. rubric: Content: 5 points, mechanics 3 pts, organization 2 pts.)
