Product Information

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 water fountains. Students find the answers to such questions as how much bacteria does soap or mouthwash eliminate, and which mouth contains more bacteria — a human or a dog.
