  • Organic waste as a resource.
  • Hot heap composting, worm farm composting, EM Bokashi composting.
  • Sustainability.
  • Natural cycles for dealing with waste.
  • Personal and social responsibility for action.

Students will learn the six important ingredients for high-quality compost and how to use them for successful hot heap composting.

Students can then either:

  1. Discover how to maintain a worm farm by correct feeding, providing suitable bedding, harvesting worm castings and preparing and using worm leachate (liquid fertilizer), or
  2. Discover how effective microorganisms (EM) can be used to compost food scraps by anaerobic fermentation.

We are learning to:

  • Explain how to use organic waste as a resource.
  • Identify the six key ingredients for successful hot heap composting.
  • Explain the process and methods of making compost at home or at school.
  • Identify actions they can take to encourage better use of organic resources in their lives
  • Identify the correct materials that go into the organics wheelie bin and explain some maintenance tips.

Using language, symbols and texts

Students will interpret images, symbols and text to understand and describe different aspects of the composting process.

Thinking

Students will use cognitive and critical thinking skills to problem-solve and expand their knowledge of different composting systems.

Managing self

Students will have the opportunity to adopt and adapt composting practices and to develop resourcefulness around organic waste.

Participating and contributing

Students will learn how to contribute to the sustainability of their home and/or school environment.

Relating to others

Students will work collaboratively and supportively to complete tasks; take turns and support their classmates.
