Testing Turbidity?

Environmental Science teachers, how about showing your students how to test water’s visibility and hence turbidity--or its opposite, clarity--with our freshwater Secchi disk? (We thought you’d like the idea.) The disk is just under 8” dia with an integral weight and alternating black and white quadrants, attached to a 72-foot nylon cord marked every foot with a hash mark. Just lower it into water and you’ll have your results, and teaching points.
