| | BACTERIA WATER TEST KIT
This lab investigation will enable your students to gain an up close understanding of the sources of bacterial contamination in water by testing water samples for coliform and other bacterial strains. Students will collect water samples, inoculate agar plates, observe bacterial smears under the microscope, and identify and count bacterial colonies. In addition, students can learn about the effects of bacterial contamination on humans as well as ways to minimize the risk of contamination. Contains materials for a class of 40 students. For grades 9 through 12.
What causes water pollution? How is it detected? How can polluted water be purified? Answer these questions and many more as you challenge your students with this hands-on primer on our most pressing environmental challenge. Using safe, easy-to-use chemical tests, students analyze local water samples for a variety of common pollutants including chlorine, copper, hardness, dissolved oxygen, nitrogen, phosphate and pH. Your class will also learn how to quantify the concentration of pollutants and determine the pollution level that poses a danger to wildlife and man.
