Local Environment - Senior Science - Stage 6 (Year 11)


  • Students draw on existing knowledge of their own local area and expand on their understanding of scientific concepts that can be identified through careful analysis of biotic and abiotic factors.
  • ¬ôStudents gain field experience of wetland ecosystems as they:
    • observe and measure some of the abiotic parameters to which the main plant and animal species are adapted
    • study trophic relationships, adaptations and population patterns
  • Students gain information and analyse their findings in order to report on aspects of the local environment that have been affected by people and propose realistic solutions to the problems that exist.


Gather information from first hand observations to construct food chains and food webs 

  • Explain trophic interactions between organisms in an ecosystem
  • Describe the role of decomposers in ecosystems, especially in relation to the nitrogen cycle
  • Measure a number of abiotic factors to compare the mangrove and saltmarsh environments
  • Use quadrats to estimate the size of a population in an ecosystem
  • Collect, analyse and present data to describe the distribution of species whose abundance has been estimated
  • Consider the accuracy of field techniques such as quadrats and transects
  • Identify factors determining the distribution and abundance of a species in each environment
  • Examine trends in population estimates for some plant and animal species within an ecosystem
  • Justify the use of different sampling techniques to make population estimates when total counts cannot be performed
  • Identify some adaptations of living things to factors in their environment
  • Identify and describe in detail adaptations of a plant and an animal from the local ecosystem.
  • Analyse trends in a plant population using a transect
  • Identify the impact of humans over the last 50 years on the ecosystem studied
