CIE IGCSE Chemistry Topic 11 REVISION (Air and water)

This revision resource contains an engaging and detailed PowerPoint (66 slides) and associated worksheets, all of which are differentiated to allow students of different abilities to access the work. The range of activities that include exam questions with explained answers and quiz competitions covers the content within topic 11 (Air and water) of the CIE IGCSE Chemistry specification for examination in June and November 2020 and 2021. The resource was written to cover as much of the content as possible but the following topics have received particular attention:

• The fractional distillation of air to separate oxygen and nitrogen
• The composition of clean air
• The variety of reactions that form carbon dioxide
• The changes in the atmospheric levels of carbon dioxide and the link to global warming
• The common pollutants and their effects on health and buildings
• The treatment of water to make it safe
• The chemical tests for water
• The conditions needed for the Haber Process

Efforts have been made during the design of this lesson to make connections between topic 11 and the other topics in order to show students how important it is to make Biological links. In addition, there is a big emphasis on mathematical skills and guidance is given throughout to break down any barriers that students may have with these types of questions.
