KS3 Biology — Infectious and Non-Infectious Diseases — Full Worksheet

🦠 Build deep understanding of infectious and non-infectious diseases with this complete, no-prep 100-mark worksheet — ready to use for lessons, homework, or revision. Infectious diseases are caused by pathogens such as viruses and bacteria and can spread between organisms, while non-infectious diseases cannot spread and are instead linked to lifestyle factors or genetics, and this resource covers it in depth for KS3 students aged 11–14.

📦 What's included:

Structured across three sections of progressive difficulty:

Section 1 (30 marks) — multiple choice on pathogens, measles, and vaccination; a true/false table with eight statements about infectious and non-infectious diseases; and a fill-in-the-blank passage using ten key vocabulary words

Section 2 (40 marks) — how measles spreads and how to prevent it; why antibiotics treat tuberculosis but not viral infections; the role of the Irish Famine in illustrating plant disease; data table analysis on non-infectious disease deaths; a discussion question on poverty and lifestyle; type 2 diabetes symptoms and management; and a disease comparison table

Section 3 (30 marks) — an evaluation of vaccination as a prevention strategy; an extended response on why non-infectious diseases disproportionately affect people in poverty; a four-part comparison of infectious and non-infectious diseases; and a patient scenario requiring diagnosis and lifestyle advice
