Part of the KS3 Science curriculum.
KS3 Science Year 8: Nutrition, digestion and health is a step-by-step online learn guide for Key Stage 3 pupils in Years 7 to 9. It covers nutrients and a balanced diet, food tests, the digestive system, enzymes and absorption, the gas exchange system, the mechanism of breathing and smoking, alcohol and drugs, then brings it all together with mixed retrieval and unit challenge.
There are 23 short steps of about 15 minutes (roughly 6 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Nutrient, Balanced diet, Iodine solution, Benedict's solution, Digestion, Oesophagus, Enzyme, Active site, Trachea, Bronchus, Ventilation and Diaphragm.
