Grades 9–12. Students investigate possible water source contamination by coliform bacteria. Using sterile technique, they collect water samples and plate them on selective media to differentiate between general coliform, Escherichia coli, and noncoliform bacteria colonies. After 24 to 48 hr, results are analyzed. In the second investigation, students analyze samples and propose design solutions to reduce the environmental impacts of human activities linked to bacterial contamination of water.
