Everything you need to teach digestion at KS3 — two complete resources, full answer keys, and no preparation required. This lesson pack covers mechanical and chemical digestion, and how carbohydrates, proteins and fats are broken down into nutrients the body can absorb, for students aged 11-14. Digestion is the process of turning large, insoluble food molecules into small, soluble ones that can pass into the blood and be used for energy, growth and repair.

The main worksheet contains 18 questions worth 100 marks across three progressive sections: knowledge recall through multiple choice, true/false and fill-in-the-blank questions (30 marks); application and understanding through short answer questions, a table completion exercise and key term definitions (40 marks); and extension and analysis through extended writing and evaluation-style questions (30 marks). The extension pack provides four enrichment activities — a 12-term vocabulary matching exercise (12 marks), a 25-mark challenge quiz with a data interpretation task, an 18-mark real-world case study, and a rubric-assessed Teach It Back creative task. Full answer keys and detailed marking guidance are included for everything.

Buying this bundle saves £1 compared to purchasing both resources separately (£3 + £3 = £6 individually, £5 as a pack).

Google Classroom ready.
