In this activity teamwork and co-operation are reinforcing activity development is always under the teacher's supervision.
•    G (green light - understand this very well)
•    A (amber light) - need a bit of support but understand the basics or...

•    Disinfection of surgical instruments simulation with Glutaraldehyde
•    Disinfection of surgical instruments simulation with ultrasonic
•    Surgical instruments cleaning and drying
•    White coat package
•    Gauzes package
•    Simulated quality control package
•    Sterilized packages storage in sterile zone
