Abstract
Task "Power of antibiotics" is based on use of disc diffusion method in school conditions. In this method, agar plates are first inoculated by bacteria, then antibiotic discs are placed on the plates.
After overnight incubation the zones of inhibition can be seen around antibiotic discs. Activity lasts overall 4 weeks (one lesson weekly).
Students work in groups of five, each student has a specific role. They are first learned about safety.
Their work consists of several steps: isolation of bacteria from environment (e.g. student's fingers), test of susceptibility of bacteria to antibiotics, evaluation and presentation of results. Task was successfully tested in selected classroom at lower secondary school.
