Set of method cards and supporting power point for an investigation: behaviour of saliva is compared with those for known sample of amylase to demonstrate that saliva contains amylase.
Discussion of controls
Because the investigation requires 4 separate experiments to be run, the class needs to be divided into teams, each team carrying out one experiment: a full picture of what the results mean can only be asrrived at when the class results are pooled - modelling how professional scientists need to work in teams and communicate their ideas and results.

A really useful resource
This is a really good activity. I like the organisation of the practical with the students organised in teams, and the links to HSW - and it has a comprehensive set of instructions and resources included. Well worth a look (the only thing missing is a set of differentiated learning objectives but you easily add your own!)
