The range of exam questions, understanding checks and quiz competitions that have been written into this revision lesson will help to motivate and engage the students whilst they assess their understanding of the content found in topic 1.3 (Digestion and the digestive system in humans) of the WJEC GCSE Biology specification. The resource includes a detailed and engaging Powerpoint (51 slides) and an associated worksheet, which has been differentiated to help differing abilities to access the work.

The range of activities have been designed to cover as much of the content as possible but the following sub-topics have been given particular attention:

  • The movement of food by peristalsis
  • The role of carbohydrase, protease and lipase enzymes in digestion
  • The tests for the presence of starch and glucose
  • The roles of the stomach and small intestine in digestion
  • The function of bile in the break down of fats
  • The need for a balanced diet and implication for health of excess sugar and salt in foods
