An introduction to the immunity topic which first explores the key terms used at GCSE level and extends the list through an active starter. The main focus of this lesson is antigen recognition, and the steps involved in phagocytosis.
Relevant statements from the AQA A level Biology specification are shared with students at the start, there are a few slides (mainly for interest) on types of organism that are dealt with by the immune system, and relative size. This leads to detailed, but straight forward explanation of phagocytosis with a link to a short clip to watch. There is a reduced version of this powerpoint which can be printed for students if you wish, so they can annotate it whilst you present the pain powerpoint rather than copying everything down.
There is an 5 mark exam question on phagocytosis with mark scheme available within the main presentation.
Finally a review of learning is covered through a gap fill and some questions which touch on some ethical issues, and these are great for stimulating some further discussion if time allows.
