Handwashing is a much discussed topic in early elementary school, but seems to be taken for granted by the time high school rolls around. This easy experiment can show students in graphic display what grows in agar when hands are not washed. There are two activities presented, one for pairs of students, and one for the whole class. In addition, there are options for widening the research and important questions to be answered by evaluating the data. Remind students how important handwashing is in preventing the transmission of microorganisms that could cause disease.
