Our GCSE courses offer students the opportunity to contextualise specification content and develop practical skills in new and inspiring environments.  

Tailored to awarding body Biology and Science GCSE specifications this course will cover key ecology subject content, as well as use of apparatus and techniques and mathematical requirements through enquiry-based activities. Students will develop their understanding of the natural world by working scientifically, developing their experimental and analytical skills. 

Students will sample invertebrates in a freshwater habitat and learn about the ways in which they are adapted to their environment. They will investigate the trophic structure of a freshwater ecosystem, constructing pyramids of number and biomass from their own data and calculating the efficiency of biomass transfers between trophic levels. 

Example Timetable

Our day courses usually run from 9:30 until 3:30, but times can be adjusted to suit your group and travel plans. There is also the option to extend the day to allow more time for fieldwork and more detailed follow up.

Fieldwork session 1

  • Sweep sampling of invertebrates in the first of two habitats/microhabitats.
  •  Identifying invertebrates using keys.
  • Measuring abiotic factors such as temperature, flow rate and depth.


  • Fieldwork session 2
  • Students will collect comparative data from a second habitat/microhabitat.


  • Analysis and evaluation of the data collected including:
  • Relating differences in invertebrates found to environmental conditions.
  • Constructing pyramids of number and biomass.
  • Calculating the efficiency of energy transfer.
