Testing the Waters
Mary E. Slack
Columbia College Science Institute
Chicago, Illinois

In this activity, students test the quality of a local body of water. Students collect water samples to study pH, dissolved oxygen, temperature, particle suspension, plants, macroinvertebrates, and vertebrates. The class compiles the data and evaluates the overall biological water quality of the study area. Students also examine the land around the sampling area to study the effects of human impact. This activity uses the Calculator Based Laboratory system with a variety of probes and graphic analysis computer software. Testing the Waters should be conducted at least twice during the school year and can be used for a long-term project.
