Biodiversity

This unit examines environmental changes and their impact on species' survival and adaptation, potentially leading to extinction. It also develops skills for interpreting data and observations, evaluating errors, and using SI units and IUPAC chemical nomenclature in scientific contexts.

This is an attributed Oak National Academy lesson sequence, not a completed or academically approved DASKEREL course. Supporting transcripts may depend on video, images, practical equipment or teacher explanation. Follow each lesson’s supervision guidance. For religious education and RSHE, follow the school’s syllabus, policy and safeguarding procedures.

This Oak index uses an earlier export and lists 5 source lessons. DASKEREL has 8 original lessons for this unit, including 3 linked to source lessons absent from that export. Read the full DASKEREL unit.

Prior knowledge

  • Food chains show the transfer of biomass
  • Food web diagrams represent several interconnected food chains within a community of organisms
  • A change in the size of a population will affect other populations in the same community
  • Habitats are where plants and animals live and they contain living (biotic) and non-living (abiotic) parts
  • Organisms interact with the environment in which they live
  • All species have features which make them suited to their environment
  • Changes to the environment may make it harder for organisms to survive in a particular habitat
  • Biodiversity is a measure of the range of living organisms
  • It is important to preserve biodiversity to maintain a healthy environment

Source curriculum references

  • Ask questions and develop a line of enquiry based on observations of the real world, alongside prior knowledge and experience
  • Use appropriate techniques, apparatus, and materials during fieldwork and laboratory work, paying attention to health and safety
  • Apply sampling techniques
  • Interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
  • Evaluate data, showing awareness of potential sources of random and systematic error
  • Understand and use SI units and IUPAC (International Union of Pure and Applied Chemistry) chemical nomenclature
  • Changes in the environment which may leave individuals within a species, and some entire species, less well adapted to compete successfully and reproduce, which in turn may lead to extinction
