KS3 Digestion & nutrition Test Paper with Mark Scheme

A 40-mark KS3 biology test paper on digestion & nutrition for Years 7 to 9: 23 questions to do in 40 minutes, building from quick multiple choice to longer written answers, with the hardest questions in a short stretch section at the end.

What's covered

The digestive system: a body diagram to label (oesophagus, liver, pancreas, large intestine), the organs food never passes through, mechanical and chemical digestion, villi, helpful gut bacteria and why faeces are egested, not excreted. Enzymes: carbohydrase, protease and lipase in a table to complete, a lock-and-key diagram to explain, and the amylase practical to read (variable, control, denaturing). A healthy diet: fibre, energy needs, food test results and a traffic-light label with a sugar calculation. Malnutrition: deficiency diseases and an energy-balance bar chart. Stretch: why muscle wastes in starvation, and how bile speeds up fat digestion.

What's included

• A cover page with space for name, class and date, and a list of what the paper covers
• 23 questions worth 40 marks, graded from easier to harder, with diagrams to label and data to read
• Lined space for every written answer
• A complete mark scheme in plain English: what earns each mark, so you can mark it with confidence even if science was a long time ago
