This REVISION resource has been written with the aim of motivating the students whilst they are challenged on their knowledge of the content in TOPIC 4 (Natural selection and modification) of the Edexcel GCSE Biology specification. The resource contains an engaging and detailed PowerPoint (82 slides) and accompanying worksheets, some of which are differentiated to provide extra scaffolding to students when it is required.

The wide range of activities have been designed to cover as much of topic 4 as possible but the following sub-topics have been given a particular focus:

  • The discovery of human fossils
  • Stone tools as evidence of human evolution
  • Evolution by natural selection
  • The development of antibiotic resistance in bacteria
  • The three domain and five kingdom classification methods
  • Genetic engineering
  • Selective breeding
  • The benefits and risks of genetic engineering and selective breeding for the growing population
  • The use of fertilisers and biological control

There is a large emphasis on mathematical skills in the new specification and these are tested throughout the lesson.

This resource is suitable for use at the end of topic 4, in the lead up to mocks or in the preparation for the final GCSE exams.
