The practical: Investigate the effect of pH on the rate at which amylase breaks down starch, and find the optimum pH of amylase.
The pack a busy department needs before the lesson: an apparatus list per group with what to check, reagents and their preparation, a risk assessment, and a lesson plan in nine timed steps from planning to evaluation. The expected-results section gives the ranges the model predicts for a careful group, labelled as the model’s, not as a promise.
Exam questions come with full mark schemes, followed by the common mistakes and what students say when they make them.
