In today’s Certified Nursing Assistant class for English language learners, the subject was germs. To illustrate the concept of germ transmission, each learner received four slices of potato, untouched by human hands. They then performed three actions: rub one slice on the floor, breathe on another, and rub the third on their hand. Next week, they’ll get to see what happens. In another exercise they used WebMD to answer questions.
