Activities for the germ theory of disease
Here are activities to help with the teaching of this topic.
Introduction to germ theory
This short set of power point slides presents data on changing causes of death in the UK since 1850 and invites discussion on these changes. It then introduces a comparison with Kenya today. It is a good way of introducing themes that will be important through several topics.

LSS: Information revolution
This activity is about information storage and retrieval, about books and journals, and about comparing print with electronic information storage. Information storage is in the process of transforming how we behave, both because of the ongoing explosion of the quantity of information available and because of increasing ease of access.

LSS: Using the internet to find information
Students first carry out an Internet search to find web sites that would be helpful to answer specific questions about a science topic. In the second part of the activity, students refine their search using a Boolean-style approach, outlined in the briefing sheet. The students then complete a related homework task.

Development of the germ theory of disease
This activity could be used as a summary at the end of the topic or as a revision exercise. It provides useful summary notes for exam revision when complete. The aim is to provide an overview and to show how the scientists they will have studied in more detail fit into a general scheme. It will encourage use of the textbook and other resources to find information.
