This classroom activity enables pupils to investigate ways of making dirty water cleaner through sieving and filtering and can also be used to explore ways of making water safe.

In Turkana in Kenya where for two out of three people do not have access to clean drinking water, Ditch the Dirt offers a;

  •  Real life global context to explore water quality, sieving and filtering investigations
  •  Perfect challenge to deliver parts of the science, D&T & maths curricula
  •  Great activity for a science or STEM club, transition or enrichment day
