This kit presents information relating to the characteristics of the air and the atmosphere, and how pollutants affect these. It demonstrates the principles of absorption and the effectsof air pollution on such common things as plants and metals.

A combination of 11-35mm slides, six reproducible transparency masters, instructor's manual and laboratory equipment leads students carefully through water quality experiments involving dissolved oxygen, the bacteria related to dissolve oxygen, water clarity, and the treatment of organic wastes.

A classroom size kit for the investigation of health and economic consequences of environmental pollution.

Nine different tests of the air and water around us can be performed with the Environmental Student Test Lab.

Learn what air pollution is and how weather and geography affect it! Conduct experiments to test the air that you breathe for pollutants.

Conduct experiments on the chemicals and organisms that pollute our water and how it can be purified. With this kit you will be able to test the level of bacteria in water, the chloride content, the pH level and the rate at which particles settle in water.

The laboratory manual and equipment allow students to do tests and experiments involving CO2 cycles in nature, composting, fuel for wastes and paper recycling.
