This is an engaging and fully-resourced revision lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 8 (Exchange and transport in animals) of the Edexcel GCSE Biology 9-1 specification.
The specification points that are covered in this revision lesson include:
- Explain the need for exchange surfaces and a transport system in multicellular organisms including the calculation of surface area : volume ratio
- Explain how alveoli are adapted for gas exchange by diffusion between air in the lungs and blood in capillaries
- Describe the factors affecting the rate of diffusion, including surface area, concentration gradient and diffusion distance
- Explain how the structure of the blood is related to its function
- Explain how the structure of the blood vessels is related to their function
- Explain how the structure of the heart and circulatory system is related to its function, including the role of the major blood vessels, the valves
- Describe cellular respiration as an exothermic reaction which occurs continuously in living cells to release energy for metabolic processes, including aerobic and anaerobic respiration
- Compare the process of aerobic respiration with the process of anaerobic respiration
- Calculate heart rate, stroke volume and cardiac output, using the equation cardiac output = stroke volume × heart rate
The students will thoroughly enjoy the range of activities, which include quiz competitions such as Where’s LENNY?” where they compete to recognise the blood vessel being described from the clues whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams.
