教學目的 1.) Making the zero waste philosophy connections of how worms eat our food scraps and other compostible materials and turn it into high nutrient fertilizer that we can put back into our soil. 2.) Learn about the basic biology of worms, and how to make an indoor bin, care and maintenance for the composting worms.
教學內容 Have each working group write down the following questions and present feedback from each group. x What kinds of soil are we going to leave for our future generations? x How does deforestation, the exploitation of our natural resources, and toxic waste spills in our oceans, rivers and lakes affect or impact our watersheds and soil? x What are some ways that we are able to heal our soil and help protect our soil from future contamination? *Discuss the impacts of climate change and global warming, thoughts, comments from students to engage a dialogue. Briefly review and watch as a class together first: English/Spanish Worm bin info sheet https://docs.google.com/open?id=1QsAt7S9Zayb4HEUo1A6SvLWtm2zbBUsOnxwDJL7I073YQB5mKvN784uM2UbW Worm Composting Basics https://docs.google.com/open?id=1COBA_AxQA0cwwTgJ6NqUnSy-XcIST8yhzeRqgmppZ1pPVicBp23BN-qcfE1- How to make your own worm bin http://www.youtube.com/watch?v=JjjuYNilM60 1.) Start dividing up all the materials for each group that will make a worm bin and refer to the worm bin instructions. Have each group designate two students to shredding compostible materials and placing them in the bin. Have another student mix together as the materials are added to the bin. Have another student pour water slowly into the bin as materials are added and mixed. Have the last student to add the worms by hand if they have no fear of worms. o Ask the follow up questions after the worm bin has been composting about six weeks. x What life is in the soil? What are some of the minerals and nutrients needed in disturbed soil? x How are worms are connected to humans?(maybe passing already made worm bins around to look at worms) *Encourage the students to smell the soil, and observe the moisture level and identify contents in worm bins that was once food scraps, newspaper, egg shells..etc. They can also record on a log, how much food they are feeding the worms each week, and checking everyday to see how fast the food is being consumed by the worms.
