Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs. In this activity, learners will get their hands "dirty" with cinnamon and cooking spray, then test and compare different ways of washing their hands. While messy, this is a great model to show learners how much time is really needed to wash dirty hands. Step-by-step instructions are included with photos. Activity guide includes a "What's going on?" explanation and connections to relevant science concepts on what are germs and how we transmit them to each other. A final section includes tips on better ways to wash your hands and when you should do it.
