The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh
