NEW AQA GCSE (2016) specification - Defence Mechanisms

This is a lesson from the NEW AQA specification on defence mechanisms of the body, from the ‘Infection and Response’ module.

This lesson is part of a 12 lesson bundle for the NEW ‘Infection & Response’ Unit, found in my TES shop - https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins by recapping on what a communicable disease is and what risk factors can increase the likelihood of a communicable disease spreading from person to person.

Students are then given an outline of a human body, they will need to label it with the various different ways pathogens can enter the body. Pupils can then mark and check their work against the examples on the PowerPoint slide. Students then discuss how your body may stop pathogens entering via these various different entry routes and you can use the information on the PowerPoint slide to highlight these various defence mechanisms. Pupils can spend time annotating their diagram to display these defences and peer-assess their work - R/A/G.

Next, is the introduction of white blood cells, you can explain their different roles using the diagrams on the PowerPoint slide and by use of the video/animation links. Pupils should then fill in a table of information using as many key words as possible, pupils should self-assess their work to check for the correct use of the key terms.

Plenary - past-paper question which I get pupils to complete in silence and hand to me as they leave (exit card). I will then mark and grade it for the next lesson, but equally they could complete and mark within the lesson.

All resources are included within the PowerPoint presentation.

Enjoy :)
