Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about evolution and adaptation (GCSE and Key Stage 3)
Evolution by natural selection is a fantastically exciting topic area. It offers enormous opportunities to think, debate and reconsider current thinking.
Students enter your classroom with a range of different experiences and ideas about evolution. Some will be vehemently opposed to accepting the theory of evolution by natural selection, citing the reason that “it is just a theory“.
However, it is important to try to move away from general debate and focus on the evidence. Students should be provided with the opportunity to see for themselves why science accepts the ideas outlined by Darwin, comparing DNA sequences can help.
When teaching evolution, I find it helpful to distinguish between (i) evolution i.e. change in populations and species over time and (ii) natural selection, the mechanism behind evolution. This excellent clip from the Tree of Life project created by the Wellcome trust is well worth a visit as the video below is a fantastic example of natural selection in action. Evolution by natural selection really involves three key ideas:
- There is variation in the population of a trait
- The trait is heritable
- There are differences in the reproductive success of individuals with that trait
Thinking deeply about evolution
Thinking questions on evolution. So you think you understand evolution? Use these questions with your class to explore and challenge their understanding of evolutionary biology. They can consider these questions together and then chose one to explore as an essay. (PDF)
