Students examine specific skills in assessing water quality from a holistic approach. They assess the health of a local watershed and identify problems in the local watershed and suggest remediation.

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

Students are introduced to biomolecules and their roles in livin systems. They are introduced to the "Elements of Life." Students write down and define the "Elements of Life." They are asked why they think those elements are essential...

First graders examine body systems and demonstrate their competency in a quiz game show. Lessons cover the brain, heart, lungs, digestive system, muscles, and bones. Students , in teams, answer teacher-created questions in the game.

Students determine how the various levels of minerals in the soil, as well as the pH of the soil, affect the growth of plants in these plant growth experiments.

This page provides very brief information about phosphorous (chemical symbol P.)

A diagram which clearly illustrates the phosphorous cycle in a somewhat technical manner.
