This revision resource has been designed to cover the content in both topic 11 (Gas exchange) and topic 12 (Respiration) of the CIE IGCSE Biology specification for examination in June and November 2020 and 2021. The topics have been combined because of the huge crossover and the aim was to encourage students to see those connections and to make the Biological links. The resource contains an engaging and detailed PowerPoint (77 slides) and associated worksheets, some of which have been differentiated to provide assistance for those students who need it.
Included in the resource are exam questions, quick tasks and quiz competitions which try to cover as much content as possible with the following areas receiving particular attention:
- The internal and external structure of the trachea
- The structure of the alveoli to allow efficient gas exchange
- The role of the ribs, intercostal muscles and diaphragm in ventilation
- The differences in composition between inspired and expired air
- Aerobic respiration in seeds
- The uses of energy in the body of humans
- Anaerobic respiration and the oxygen debt
This resource contains a large emphasis on the mathematical element of the Biology course. Students are guided through key skills such as percentage change and then challenged to apply
