Glo Germ is made from tiny particles that are only visible under ultraviolet light. These glowing particles represent germs. Prior to class, the teacher applies the Glo Germ liquid or powder to his or her hands. As students arrive to class, choose two or three students, and shake their hands. The students who shook your hand, will have a glowing hand.
Scan objects that the glowing students have touched.
Those objects will also glow, indicating germs are present. To teach proper hand washing, have students apply Glo Germ to their hands. Then vary the washing times of the students' hands. Scan all the hands under the ultraviolet light to see how long you should wash your hands to remove all the germs. Glo Germ is a product of the Glo-Germ Company of Moab, Utah.
