1. Germ Theory of Disease - John Snow


This activity is for use in class with alternative reading and discussion of a question. It teaches an interesting and important story in the history of the Germ Theory of Disease. It also introduces some key ideas about how a scientific theory develops. These will be expanded and reinforced later in the course.

5. Examining evidence for the effect of carbon dioxide on the temperature – cpdn


This activity from the climate prediction.net site looks at the uncertainty in some information about past climate. It shows how a set of different pieces of evidence together provide support for a theory.

8. We should be so lucky


This activity allows students to read an article about the possibility of extra-terrestrial life and to criticise some of the assumptions and arguments used in the debates.

9. Modelling scientific research with playing cards


This activity is one way of using a pack of playing cards to model the process of scientific research through observation, generating hypotheses and then testing the hypotheses until a rule is found that fits all the observations. It was written by Tom Mc Goldrick who is an SPU teacher at City and Islington College, London.

10. Measurement errors


Some ideas for a quick activity to demonstrate the inherent error in any measurement, using thermometers, watches or rulers. It shows how even a simple measurement is subject to both random and systematic error.
