AQA Trilogy GCSE (9-1) Biology – Breathing & Gas Exchange
This lesson is designed to meet specification points for the NEW AQA Trilogy Biology specification, particularly the ‘Organisation’ SoW.
 
This lesson begins with a video on breathing and the organs of the respiratory system, pupils are provided with a list of questions which they will need to answer using the information in the video. Once the video is finished they can then self-assess their work using the answers provided.
 
Pupils are then provided with an information on breathing and gas exchange, they are also given a worksheet that they will complete using the information. For lower ability classes it would be best to read through the information as a class, tag-reading, so that they are more familiar with certain words before starting the worksheet.
 
Once completed the answers provided on the PowerPoint slide mean pupils can either self-assess or peer-assess their work.
 
The next task is a mid-plenary, pupils will need to copy and complete the sentences and then mark their work.
 
The next part of the lesson is on adaptations of alveoli, pupils will copy a table off the board and will each be given a card of information. Either discussing on tables or walking around the room pupils will need to complete their table on the four main features of alveoli which make them efficient gas exchange surfaces.
 
The final activity is an exam-style question worth 6 marks, pupils can close their books and sit in silence to complete this task. Once finished they should mark their work.
 
Plenary task is to write a twitter message about what they have learnt this lesson, including #keywords.
