The Challenge

What will your learner investigate?

Can you design a filter that makes dirty water visibly cleaner and explain its limitations?

Learning outcomes

  • Identify filtration as a separation process.
  • Select and arrange materials based on their properties.
  • Test water before and after filtration and evaluate the design, recognising that filtered water is not automatically safe to drink.

Connected learning

Science: materials, mixtures and separation; Geography: water resources; Mathematics: volume and data; Citizenship: access to clean water.
