Assess students' understanding of how handwashing and covering coughs reduce the spread of germs by testing knowledge of when to wash hands (e.g., after using the bathroom, before eating, after coughing/sneezing), the key steps and duration for effective handwashing (soap, scrubbing for ~20 seconds, rinsing and drying), proper cough-covering techniques (using a tissue or elbow, disposing tissue, then washing hands), and ability to choose and explain appropriate hygiene actions in everyday classroom and home scenarios.
