• This is an individual activity. • Ask learners to read through the passage in the Learner’s Book. • Take them to the library and ask them to look up information about pasteurisation, anthrax, rabies, vaccination or scientists who have developed cures for diseases.


• Ask them to make notes and have a class discussion on the outcome of their research. Ask each learner to contribute to the discussion.


Background knowledge Pasteurisation of fresh milk involves heating it to about 60 °C for 15 to 20 seconds. Anthrax is caused by the bacterium Bacillus anthracis. It is a lethal disease which is spread by spores, affecting humans and animals. The spores are very stable, which is why they could potentially be used as a biological weapon. There is a vaccine available against anthrax. Rabies is caused by a virus and can spread from animals to humans. It causes disease in the brain and subsequent death, but there is a vaccine available to protect animals and humans against it.
