Environmental Chemistry: Nitrates, Phosphates, and Eutrophication

Ideal for Teaching the Value of Fresh Water

After completing this lab, students will learn about the importance of protecting and conserving a valuable resource: fresh water. They will gain an understanding of the difference between point source and non-point source pollution and the role of nitrates and phosphates in the process of eutrophication. The lab also helps students learn about the variety of factors, including natural ones, that contribute to the overall problem of water pollution. They will observe and examine the effects of nitrates, the effects of phosphates, and the effects of a combination of nitrates and phosphates in miniature “ponds.” Kit contains materials for 15 groups, Teacher’s Manual, Student Study Guide, and copymasters.
