This survey enables students to get a glimpse into how important it is to practice good hand hygiene and be cognizant of how easily diseases are transmitted. I typically had students observe classrooms during instruction time, but I have also given students the survey and asked them to complete it over an entire day. The results are astonishing. The students are usually grossed out and the activity really stimulates great discussions. I typically administer this survey when teaching the immune system. I always receive positive feedback from the students and they claim that they see things much differently after the activity. Awareness is key to disease prevention.
