Grades 912. Students can see the effects of air and water pollution all around them; however, soil pollution is harder to spot. In this activity, your students grow their own rye grass ecosystem and use it to experiment with different levels of pollutants. They can see firsthand how pollution impacts primary productivity and the flow of energy in the terrestrial system. Students also learn to estimate pollution’s impact on productivity by performing biomass measurements. Kit accommodates 32 students working in groups of 4.
