One of a set of three secondary activities produced by the Association of Science Education (ASE) in collaboration with Practical Action for the Global Learning Programme England. In these lessons students discover how people in the developing world are using science to improve their own lives; carry out an investigation, and consider how learning from the developing world could be of benefit to us in the UK.
Each lesson comprises a PowerPoint presentation, which incorporates student worksheets, and comprehensive teacher notes with links to useful secondary sources of information and suggestions for extension activities which could be carried out in a STEM or science club.
In this lesson students look at how the Tanzanian Government has solved problems caused by iodine deficiency by iodinising their salt. They work scientifically to discover why iodine is so important to diet, and make an informed decision as to whether or not it should be added to salt in the UK.
