What everyone needs to know:


  1. Understand what a species is.
  2. State what is meant by variation.
  3. State that children look like their parents because they inherit genes.
  4. Understand that some variation is genetic and some is environmental.
  5. State that genes are instructions for characteristics.
  6. State that genes are made of DNA.
  7. Understand that the work of many scientists contributed to our understanding of the structure of DNA.
  8. State what living things need in order to survive.
  9. Understand that organisms that are better adapted are more likely to survive to pass on their genes.
  10. State that selective breeding is used by farmers to breed animals with useful characteristics.
  11. State some reasons why an organism may become extinct.
  12. State some reasons why zoos and seed banks are set up.


  1. Describe how scientists classify organisms.
  2. Describe the difference between continuous and discontinuous variation.
  3. Explain why children look similar to their parents.
  4. Identify genetic and environmental variation.
  5. Describe the difference between DNA, genes and chromosomes.
  6. Describe the work of Watson, Crick, Wilkins and Franklin in the development of the DNA model.
  7. Describe how natural selection occurs.
  8. Describe how to use selective breeding to breed an animal with a desired characteristic.
  9. Understand what is meant by genetic modification.
  10. Link adaptation to extinction.
  11. Explain how zoos and seed banks help to prevent extinction and maintain Earth’s biodiversity.


  1. Explain why scientists classify organisms.
  2. Explain why siblings like similar but not identical.
  3. Apply the function of DNA to explain why people have different characteristics.
  4. Evaluate the importance of the discovery of the structure DNA.
  5. Explain how adaptations help an organism to survive.
  6. Explain how Darwin came up with his theory of evolution by natural selection.
  7. Evaluate the use of genetic modification and selective breeding.
  8. Evaluate the effects of extinction on the ecosystem.
  9. Evaluate the use of zoos and seed banks by thinking about their benefits and drawbacks.

What is being taught week by week:

Week 1: This week was a welcome to the school and an introduction to the course.

Week 2: This week, we look at the the classification of animals. How they can do identified and named scientifically.

Week 3: Having seen what a species is, we are now looking at variation within a species.

Week 4:
