Description
Great for small groups or for students who are working at home!
This kit helps students understand the importance and value of fresh water and the need to protect and conserve this valuable resource. They learn that a variety of factors, including natural ones, contribute to the overall problem of water pollution. After completing this lab, students should understand the difference between point source and non-point source pollution, as well as the role of nitrates and phosphates in the process of eutrophication. Students observe and examine the effects of nitrates, the effects of phosphates, and the effects of a combination of nitrates and phosphates in miniature “ponds.” Contains enough materials for 5 groups and includes teacher’s manual and student copy masters.
This kit addresses the following Next Generation Science Standards*:
