A fully-resourced lesson which includes a detailed and engaging lesson presentation (36 slides) and an assistance worksheet for those students who feel that they need extra assistance with the final description. This lesson looks at how body temperature is controlled in humans through a homeostatic mechanism and includes details of a negative feedback loop.
The lesson begins with a three pronged task where students have to use the clues to come up with the word homeostasis and the number 37 and then see if they can make the link in the human body. Time is taken to ensure that students recognise why maintaining the temperature around this set-point is so crucial in terms of the effectiveness of enzymes in reactions. There is a real focus on key terminology throughout such as thermoreceptors and hypothalamus and guidance is given on how to use these terms accurately. Discussion points and progress checks are written into the lesson at regular intervals so that students are encouraged to challenge the Biology whilst being able to assess their understanding. They are shown how to write a detailed description of the response to an increase in temperature so they are able to form their own description of the response to a fall in temperature.
This lesson has been written for GCSE students but is perfectly suitable for older students studying thermoregulation at A-level and want to revisit the knowledge.
