Caution, Microbes!
Game
Caution, Microbes! is an interactive game where students use skill and observation to explore how infectious diseases spread, what symptoms they cause, and which defenses can stop them. Each microbe appears as a “wanted criminal” with its own profile, and learners investigate by choosing protections, identifying pathogens, and testing different treatment strategies.
