How Antibiotic Resistance Develops and Why It Matters (Teach This Topic)

This guide supports teaching about how antibiotic resistance develops in bacterial populations and why it matters for medicine. It follows the finished lesson while adding concise prompts, checks and one optional modelling activity. The learner should connect genetic variation, selection pressure, reproduction and spread. Keep the distinction clear: bacteria can be resistant, but a person does not become resistant to antibiotics.
