Pathogens and Communicable Disease — Interactive Lesson (Ages 14–16)

Malaria, cholera, measles and HIV — how do germs spread, and how can we stop them? This 22-slide interactive lesson on communicable disease takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Pathogens and Communicable Disease in GCSE Biology

Pupils name the four types of pathogen — bacteria, viruses, protists and fungi — and sort diseases by cause and by how they spread: air droplets, contaminated water, direct contact and vectors. They study malaria, carried by the Anopheles mosquito, and cholera, spread in dirty water and treated with oral rehydration solution, and explain why antibiotics kill bacteria but not viruses.

What Pupils Will Learn

• Name the four types of pathogen.
• Describe how communicable diseases spread.
• Explain how malaria is spread and prevented.
