OLogy: Test Density with a Supersaturated Solution

Do fresh water and salt water mix? Find out in this experiment.

The place where the lower end of a river meets the ocean is called an estuary (ES-choo-AIR-ee). What do you think happens when the rush of freshwater collides with the gush of the ocean’s tides? Do the two kinds of water instantly mix? Does the freshwater float on top of the salt water? Or does the salt water float on top?
