OCR GCSE 21st Century Chemistry

Chemistry, like Biology and Physics, consists of three written papers and a controlled assessment:
Modules are those from Core Science (C1, C2, C3) and Additional Science (C4, C5, C6) and Further Additional Science (C7).

Course content

C1: Air quality Module

• Which chemicals make up air, and which ones are pollutants? How do I make sense of data about air pollution?
• What chemical reactions produce air pollutants? What happens to these pollutants in the atmosphere?
• What choices can we make personally, locally, nationally or globally to improve air quality?

C2: Material choices Module

• How do we measure the properties of materials and why are the results useful?
• Why is crude oil important as a source of new materials such as plastics and fibres?
• Why does it help to know about the molecular structure of materials such as plastics and fibres?
• What is nanotechnology and why is it important?

C3: Chemicals in our lives – risks and benefits

• What were the origins of minerals in Britain that contribute to our economic wealth?
• Where does salt come from and why is it so important?
• Why do we need chemicals such as alkalis and chlorine and how do we make them?
• What can we do to make our use of chemicals safe and sustainable?
