The practical: Investigate how the volume of sodium hydroxide solution added to hydrochloric acid affects the temperature of the mixture, and use the graph to find the volume that neutralises the acid.
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.
