In this activity, students research the effect of common pollutants on our waterways and hold a mock trial to determine the worst pollutant in the country.

By the end of this activity, students should be able to:

  • understand what is polluting our waterways
  • understand that how detrimental a pollutant is to the environment depends on how harmful it is, how often and how much it contaminates and how easy it is to clean up
  • realise that the best way to control pollution can mean stopping it from happening in the first place
  • research an issue to understand different ‘sides’, then argue for and against it with others.
