Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram staining. Finally, they analyze their results to determine what type of bacteria is growing in the yogurt.
