This learning module familiarizes students with the isolation, observation, and identification of bacteria and the removal of sediment from water. In addition, it is designed to promote the skills of observing, communication, analyzing, and inferring in a "hands on" classroom environment. The module includes several student activities and teacher demonstrations designed to incorporate environmental engineering and microbiology techniques into the science classroom. Activities included are a bacterial diversity test, T-streak test, pH test, temperature test, mouthwash effectiveness test, removal of sediment from water exercise, and the determination of water clarity by absorption. Student handouts and answer keys are included in the form of appendices.
