PAPER 4 FOUNDATION TIER REVISION (AQA GCSE Combined Science)

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics C6 - C10, that will assessed on PAPER 4. It has been specifically designed for students on the AQA GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.

The lesson has been written to cover as many specification points as possible but the following sub-topics have been given particular attention:

• Hydrocarbons
• The first four members of the alkanes
• Fractional distillation of crude oil
• The properties of the different fractions
• The complete combustion of a hydrocarbon
• Detecting carbon dioxide, oxygen, hydrogen and chlorine gas
• Changes in the carbon dioxide levels in the atmosphere
• Deforestation
• Polluting gases
• The formation of acid rain
• The treatment of water
• The collision theory

In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as the changes in the Earth’s atmosphere.

Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 2/3 teaching hours to complete the tasks and therefore this can be used at different points throughout the course as well as acting as a final revision before the PAPER 4 exam.
