This is a one-day lesson intended to fill a 60-75 minute class period. It is intended to review basic safety and sanitation principles with students as well as extend learning into deeper topics. This lesson is intended to be a review, but also to fill in gaps in student learning and understanding. The worksheet aspect is so that students have a tangable take-away from the activity. It also slows them down and makes them absorb the information more.
