With the Nitrates, Phosphates & Eutrophication Kit, kids learn the importance and value of fresh water. Plus, understand why it's vital to protect and conserve this valuable resource. Through experiments, students discover that natural and manmade factors contribute to water pollution.

After this lab, students will know the difference between point source and non-point source pollution. They'll understand the role of nitrates and phosphates in the eutrophication process. They will observe and examine the effects of nitrates, phosphates, and a combination of both in miniature “ponds.”

From Innovating Science, the Nitrates, Phosphates & Eutrophication Kit has enough materials for 5 groups. Teacher’s Manual and Student Study Guide copymasters are included.

You provide water sample. A microscope is optional.
