This complete Disease bundle contains six fully‑planned lessons and a high‑clarity Knowledge Organiser. Students explore how diseases arise, spread, and are prevented through pathogens, body defences, vaccination, antibiotics, lifestyle factors, and global health.
The Knowledge Organiser includes key insights such as “Tar is a sticky carcinogen that paralyzes cilia, causing mucus buildup and lung cancer” and “Phagocytes are white blood cells that engulf and digest invading pathogens.”
The full lesson sequence builds scientific reasoning, data‑analysis skills, and understanding of health and prevention.

• Big Ideas: dietary imbalance, smoking, alcohol, drugs, immune defences
• Key vocabulary: deficiency, obesity, carcinogen, pathogen, antibody, phagocyte, addiction
• High‑value questions on lifestyle, immunity, and disease mechanisms
• Concise, visually structured summaries for independent revision
