Make it concrete
Analogy
Vaccination and drugs is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Vaccines contain a harmless form or part of a pathogen.
Vaccination stimulates memory cells so the immune response is faster later.
Painkillers treat symptoms but do not kill pathogens.
