This revision resource contains an engaging PowerPoint (44 slides) and associated worksheets, all of which have been differentiated two ways to allow students of differing abilities to access the work. The range of activities cover the content of Topic C11 (Air and water) of the CIE IGCSE Combined Science specification, for examination in June and November 2020 and 2021. The aim was to cover as much of the content as possible but the following topics have received particular attention:
- The composition of clean air
- Changes in atmospheric carbon dioxide levels
- The formation of carbon dioxide
- Common air pollutants and their effects on health and structures
- The treatment of water to make it safe
- The chemical tests for water
A number of quiz competitions are included in the lesson such as “POLLUTE the air…with the answer” where students compete to be the first to identify a common pollutant from the clues. These competitions act to engage them whilst the exam questions and quick tasks will enable them to assess their understanding of the content.
