A fully resourced GCSE Biology lesson introducing the key concepts of homeostasis and negative feedback. This lesson helps pupils understand how the body maintains stable internal conditions through automatic control systems and why these processes are essential for survival.

Using clear explanations, retrieval activities, vocabulary development and GCSE-style questioning, pupils explore how receptors, coordination centres and effectors work together to regulate blood glucose levels and body temperature. The lesson includes detailed coverage of insulin, glucagon, glycogen, the pancreas, the liver, thermoregulation and the differences between Type 1 and Type 2 diabetes.

A highlight of the resource is the extended GCSE Examiner activity, where pupils evaluate weak exam responses, identify errors and improve answers using GCSE mark scheme principles, helping to develop both scientific understanding and examination technique.

Designed for mixed-ability GCSE learners, this lesson is suitable for first teaching, intervention and exam preparation.
