WJEC GCSE Physics Topics 2.7 - 2.9 REVISION

This revision lesson is fully-resourced and the engaging PowerPoint and accompanying resources have been designed to challenge students on their understanding of the content detailed in topics 2.7, 2.8 and 2.9 of the WJEC GCSE Physics specification. It was decided that the close links between the types of radiation, half-life and nuclear energy lent themselves to a combined revision resource.

The lesson was written to cover as much of the topics as possible but the following points have been given particular attention:

• The nucleon and proton number and the numbers of neutrons and protons in an atomic nucleus
• Recognising and representing isotopes
• Calculating the half-life when given information about the radioactive count
• The differing penetrating powers of the three types of radiation
• Background radiation
• Sources of background radiation and possible reasons for varying levels of radon gas
• Nuclear decay equations for alpha and beta decay
• Nuclear fission and nuclear fusion
• Representing a nuclear fission reaction in an equation

The wide range of activities which include exam-style questions with fully-explained answers, differentiated tasks and quick quiz competitions will engage and motivate the students whilst they recognise the areas of these topics which will require their further attention

It is estimated that it will take in excess of 2 hours of GCSE teaching time to complete this lesson
