Natural selection teaching resources

Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about evolution by natural selection (GCSE and Key Stage 3)

Understanding evolution by natural selection

GCSE questions to help understand evolution by natural selection. This teaching activity uses a simple example of ducks crossing the road to challenge students’ understanding of evolution. It uses the video above to engage students and introduce the context of the lesson. Students are made to think about differential survival and adaptation from a concrete starting point. They work in groups to use the principles of evolution by natural selection to think about which duckling would survive and the consequences to the population. (PDF)

Evolution of antibiotic resistance

GCSE questions on the evolution of antibiotic resistance. Students use their understanding of natural selection to explain antibiotic resistance in bacteria. They read about a patient who has become infected with penicillin-resistant bacteria and advise the doctor on what to do next. (PDF)

Antibiotic resistance in action

This news story from the BBC about the ‘world’s worst’ super-gonorrhoe will grab students’ attention. Neisseria gonorrhoeae was found to be resistant to common antibiotics, with only one potential antibiotic remaining to try.
