Triangle puzzle on polymers where students match sentence fragments to construct a large hexagon. It is a revision activity which works across the ability range and is enjoyed by students. This could be used for groups of three, and it works well as a race. An answer sheet is provided. Introduction to refining and polymerisation. An onscreen cloze/labelling activity written in Excel; it ticks each word as students get them correct. Students like it because it gives immediate feedback. I’ve used it with all ability groups at GCSE. If you want to work out how it’s done, the password to unprotect it is ‘eliziczac’. Save as a template to stop students overwriting the original. Works well on a VLE.

Standalone A-level cholera data handling and accompanying powerpoints and worksheets. The main powerpoint introduces cholera and explains how it affects the small intestine’s transport proteins leading to diarrhoea. The second shows the December 2008 Cholera outbreak in Zimbabwe using UN data. The lesson can be introduced with news clips/articles (a search for ‘Zimbabwe 2008 cholera outbreak’ turns up lots). An understanding of the mechanism of cholera infection is not needed to deal with the data handling - which is very much aimed at reliability, sampling and so on. Written to support A-level Biology.
