Product Description
Students conduct their own easy-to-perform, completely hands-on bacteria tests. They simply melt the provided media in a microwave, pour their own media plates and test for growth using a series of experiments, including testing of common use items such as bathroom handles, door knobs and wate fountains. Students find the answers to questions such as - how much bacteria does soap or mouthwash eliminate, and which mouth contains more bacteria, a human or a dog? Worksheets include an overview of the experiment, equipment required, safety tips, the hypothesis, step-by-step procedure and an explanation of the results. Includes materials for four student groups - prepared nutrient agar, 20 gamma-radiated peti dishes, 10 sterile swabs, four lab instruction sheets
