In this article, Jill Law describes a lesson for sixth-grade students involving eutrophication and run-off.
"We use three shallow containers, plastic wrap, paper towels, and a cloth towel to simulate three different ground cover types. We use black pepper as the contaminant and pour water over our “substrates” to simulate precipitation. We set up gently sloping ramps that angle into the containers, each with a different substrate covering the ramp. We sprinkle the pepper evenly across the surface of each substrate and slowly pour water over the substrates.
After contamination and precipitation are completed, we compare the amount of water that ends up in each container. Next, we look into the water to see if there is a visible difference in the amount of pepper that we can observe in each."
