Natural and Artificial Selection - Evolution

✓ Engaging powerpoint
✓ Recaps previous linked learning
✓ Lots of AFL tasks and activities
✓ Past paper questions and mark scheme

This lesson on Natural and Artificial Selection is designed for KS4 Science students enrolled in the CIE Cambridge IGCSE Biology 0610 (2023-25) course. This is the third and last lesson in the topic 18 Variation and Selection.

The lesson recaps previous learning from other linked topics to ensure students have a strong foundation before diving into the material. It also includes concise and easy-to-understand information and a variety of quick assessment for learning tasks to help students solidify their understanding of the topic. Just glance through the PowerPoint presentation and you are ready to go!

This resource also includes past paper questions for optional printing alongside a mark scheme to further deepen students’ understanding.

Objectives

• Describe natural selection with reference to: (a) genetic variation within populations, (b) production of many offspring, © struggle for survival, including competition for resources, (d) a greater chance of reproduction by individuals that are better adapted to the environment than others, (e) these individuals pass on their alleles to the next generation
• Describe selective breeding with reference to: (a) selection by humans of individuals with desirable features, (b) crossing these individuals to produce the next generation, © selection of offspring showing the desirable features
• Outline how selective breeding by artificial selection is carried out over many generations to improve crop plants and domesticated animals and apply this to given contexts
• Describe adaptation as the process, resulting from natural selection, by which populations become more suited to their environment over many generations
• Describe the development of strains of antibiotic resistant bacteria as an example of natural selection
• Outline the differences between natural and artificial selection

This lesson would also be adaptable for all GCSE students (whether AQA, Edexcel, OCR) and great for KS3 Science or as a GCSE revision resource.
