Temperature regulation (WJEC GCSE Biology)

The engaging Powerpoint and accompanying worksheet which come as part of this lesson resource have been designed to cover specification point 2.5 (k) as detailed in the WJEC GCSE Biology specification which states that students should understand the roles of the effectors in temperature regulation. A wide range of activities which include Biology and Maths tasks and quiz competitions are interspersed with understanding and prior knowledge checks so that students are engaged and motivated whilst learning the key content in a memorable way and checking their progress. Students will learn that the body temperature is maintained at 37 degrees celsius by a homeostatic control system called thermoregulation and will be challenged to recall the topic of enzymes to explain why this is so important. Time is taken to look at the responses brought about the effectors such as vasodilation and shivering and links are made to the structures of the skin such as the involvement of the erector muscles. Students will recognise how these mechanisms lead a decrease or increase in body temperature back to the set point. Links are also made between the Sciences so that there is a deeper understanding of exactly why sweating cools the body down.

This lesson has been designed for students studying the WJEC GCSE Biology course but is suitable for older students who are studying Biology at A-level and need to recall the key details of thermoregulation.
