What can we do to reduce ocean plastic pollution?

Lesson overview

This first lesson in this design and technology Key Stage 3 (KS3) unit introduces students to ocean plastic pollution. Students learn how the waste hierarchy is used to encourage a reduction in plastic use. Using the various teacher resources students will link the waste hierarchy to the life cycle of plastic, thinking about how the methods used in recycling link to those used in the redesign processes and how those affect the lifetime of plastic products.

Learning outcomes
  • List the uses of plastics
  • Discuss the importance of plastic
  • Define the 6 Rs
  • Evaluate the effectiveness of recycling in the UK
  • Describe the life cycle of plastic
