Pathogens & the Immune System
Explain how pathogens (bacteria, viruses, and fungi) cause disease and describe how the immune system responds, including the roles of white blood cells (phagocytosis, antibody production) and the concept of immunity

Teaching Table
Set out your lesson
Explain two immune defences and separate infection from symptoms.
Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.
Check readiness rather than assuming source graph order establishes attainment.
Use pathogen/function cards only; no germs, bodily samples or personal vaccination history. This is general science, not medical advice.
Use the supplied stage cards on screen or scrap paper; adult key stays separate.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Explain how pathogens (bacteria, viruses, and fungi) cause disease and describe how the immune system responds, including the roles of white blood cells (phagocytosis, antibody production) and the concept of immunity
Bounded objective: Explain two immune defences and separate infection from symptoms. Pathogen disease examples are not supplied; that portion remains blocked. No diagnosis, vaccine schedule, individual protection estimate or experiment.
- partial: Distinguishes between bacteria, viruses, and fungi as pathogens with examples of each
Group distinctions supplied, but specific disease examples absent.
- partial: Explains two ways white blood cells destroy pathogens (engulfing and antibodies)
Engulfing and antibody production taught and recalled.
- partial: Explains how vaccination works and why it prevents disease
Vaccine training described with no perfect-protection guarantee or schedule.
- partial: Explains the difference between being infected and being ill
No-symptoms claim refuted; not diagnosis.
- partial: If {{name}} got a cold, could they explain what type of pathogen caused it, how the immune system tries to fight it off, and why a vaccine for flu won't protect you from all colds?
Try offers taught-content-recall for the bounded objective; it does not establish every part of the source assessment. Pathogen disease examples are not supplied; that portion remains blocked. No diagnosis, vaccine schedule, individual protection estimate or experiment.
Pathogen disease examples are not supplied; that portion remains blocked. No diagnosis, vaccine schedule, individual protection estimate or experiment.
