Grading Tips
Step 3 (Scrub) is the most important step for this lesson! Check that students have included the picture with the musical notes here, as it represents the 20-second scrubbing time.
Some students may mix up Wet and Soap . While some people apply soap to dry hands, the video and CDC recommendation is to wet hands first, then apply soap.
Ensure Dry is always the final step to prevent re-contamination from wet hands touching surfaces.
