How would it work in a school?
Having a worm farm is popular in Enviroschools. Here is an example of how an Enviroschool can deepen real learning and actions to make wider connections from worms:
Students may just learn how a worm farm works and enjoy the actions for being kaitiaki/guardians of the worms.
A next step, or at another Year level of an Enviroschool, is when they see how the worms turn their food waste into a resource, which could be given away or sold, or used for a garden as nature intended. They may choose to develop or revisit a garden. A garden is a rich learning resource on its own for a range of science and problem solving activities. Depending on the purpose or goal that students may want to reach then the worm farm resource and/or garden can then become a local resource for a wide variety of other purposes.
At Bronze level, the Enviroschool may just use their garden produce in their school or early childhood. At a Silver level, they may also be feeding their chickens, or fundraising, or exchanging with the community. At a GreenGold level this same worm farm may be supporting a garden that is also specifically catering for meals for their neighbours without a garden.
Students who are knowledgeable start to understand the bigger picture of their community, and plan a sustainable action that benefits their community.
