Digestive Enzymes and How They Work - KS3 Biology Extension Pack

🚀 Four ready-to-use enrichment activities for KS3 Biology students who've mastered the basics of digestive enzymes — ideal for extension tasks, homework, cover lessons, or stretching high achievers. No preparation required. Suitable for students aged 11-14.

Digestive enzymes are biological catalysts that break large food molecules into small, soluble ones the body can absorb.

📝 Each activity targets higher-order thinking: a 12-term vocabulary matching exercise (12 marks) covering terms such as catalyst, substrate, active site and denatured; a 26-mark challenge quiz with multiple choice, true or false and a temperature results data question; a 20-mark pineapple and jelly case study; and a creative Teach It Back task where students write a one-page guide for a Year 5 pupil, assessed with a provided rubric. Full answer keys and marking guidance are included. Comes as a PDF and an editable Word file (DOCX).
