Learn how environmental scientists study pollution by testing air and water samples from your local area! This kit includes nine different tests to determine the air and water quality of samples you collect from your community. Investigate your water quality by testing for dissolved oxygen levels, water hardness, pH, and phosphate and chloride content. Then, test for particulate and chemical pollutants in the air, measure smoke density, and learn how excess carbon dioxide in air can affect your environment. Teacher’s Manual and Student Worksheets included. There are enough materials for a class of 30 working in groups.
