Key Stages 3 and 4

Supporting the national curriculum at KS3 and KS4 

Activities linked to the science and geography objectives at both key stages 3 and 4 are supported through our education service.


A visit to our water treatment or water recycling (sewage treatment) works is a great way to see how science is applied practically. 

Subjects and areas covered during a visit can include: 

  • chemistry 
    • earth’s water resources and obtaining potable water 
    • pH scale for measuring alkalis/acids 
    • separating mixtures (filtration) 
  • biology 
    • aerobic/anaerobic respiration in micro-organisms 
    • ecosystems and the role of micro-organisms 
    • health and disease 
    • physics 
    • burning fuels 

Pupils can develop their scientific thinking by understanding how we use scientific processes, for example, the use of chemicals to balance pH or sterilise water contaminated with potentially harmful bacteria. 

They can also discover: 

  • how micro-organisms are used as a fundamental part of the water recycling process 
  • how sludge is extracted from sewage is recycled in anaerobic digesters to provide fertilisers for farmers and a way to obtain methane gas to generate electricity and fuel vehicles. 

A visit to one of our education centres is also an opportunity for pupils to: 

  • improve their experimental skills and strategies 
  • carry out measurements through activities such as water testing 
  • analysing and evaluating the outcomes of the tests. 

Alternatively our education advisors can visit your school to deliver these KS3 and KS4 activities. 


The environment is fundamental to the services we provide and we are striving constantly to improve the ecosystems in which we work. 

This links to a variety of geographical objectives and means we can support the curriculum in the following areas: 

  • physical geography
    • rocks, weathering, soils, weather and climate 
    • hydrology and coasts 
  • human geography 
    • how processes influence and change landscapes 
    • how human activity relies on effective functioning of natural systems 
    • population and urban developments 
    • use of natural resources. 

Our water treatment, water recycling centres and reservoirs are in or close to Areas of Outstanding Natural Beauty and Sites of Special Scientific Interest. 

Students can learn how we work with organisations such as wildlife trusts and the Environment Agency to protect or improve natural habitats and river catchments. 

A visit to one of our sites is a good opportunity to carry out fieldwork, allowing students to collect, analyse and communicate data. 

Want us to come to you?

With each visit, we design a programme to tie in with your objectives and class teaching.
