Eighth graders examine how humans affect various ecosystems. In this ecology lesson, 8th graders discuss different ways that contaminants enter the stream. They explain the consequences of eutrophication in lakes.

Discusses the chemistry of nitrate, the negative agricultural effects of too much nitrate in soil and in water sources, its toxicity to plants and livestock, and the impact on human health.

Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and uses the Colorimeter to measure nitrite and calculate the nitrate...

Learning module focuses on measures of variability such as range, variance, and standard deviation which are used to examine nitrate levels and water quality.

This site features a map of the United States which indicates areas with the highest risk of nitrate contamination in ground water. Links to a description of ground water contamination in U.S.

In this limiting reagents problem, students are asked to determine the amount of silver nitrate dissolved in a solution by performing a reaction with solid NaCl. In this randomized activity, each student is given a different unknown...

This site talks about the nitrate and nitrogen forms that can be found and how to test for it. Includes illustrative diagrams and graphs.

Learn about the chemical properties of silver nitrate and the variety of ways in which it is used by humans.

A lab experiment, in a series of experiments, that investigates fisheries. In this lab, students test the effects of fertilizers and other pollutants on a model ecosystem. Students also examine 2 years of ocean color (chlorophyll...

Complete directions for a teacher demonstration in which the electrolysis of a solution of silver nitrate is viewed under a microscope. Helpful tips and a diagram of the apparatus and set-up is provided. Easily adaptable as a student lab...

Activity uses water-quality data from Rock Creek Park to illustrate elementary statistical measures of exploratory data analysis. The focus of the lesson is the nutrient limitation in a stream and the three measures of central tendency.

This science fair project shows you what you need to make an endothermic reaction, the coldness of which is governed by the amount of ammonium nitrate used. The Science Buddies project ideas are set up consistently beginning with an...

A nice juxtaposition of endo- and exothermic reactions. Outlines two demonstrations. Barium hydroxide, sodium acetate, ammonium nitrate, ammonia.

Students visit three sites to investigate the areas where there is very high sensitivity for ground-water pollution. They also test the quality of water, measuring the dissolved oxygen, pH, total phosphate, nitrates, turbidity, and...
