The Invaders - DRAW IT!

A resource aimed at GCSE or Advanced Level Biology students that introduces the concept of pathogens, mechanisms of disease and non-specific defence mechanisms including barriers, inflammation and phagocytosis.

The activity is part of the DRAW IT! series of tasks which serve as a great way of getting students to understand a lot of complex information quickly. The class is split into two, with one half receiving written descriptions and being required to draw illustrations for each piece of information; meanwhile the other half of the class receives the illustrations and is required to write written descriptions. After both sides of the class have finished (or after a pre-determined time interval has passed), each student should be paired up with someone who has completed the opposite task to them. They then spend a brief period of time verbally summarising each process to each other. Finally, a class discussion is held between students and teacher, with questioning used to check understanding and a breif summary produced on the main board.
