How to teach composting?
I need to fine tune my lesson plan on composting and need your help. This lesson will be provided to children from grades 4th through 7th. It is a volunteer project for the master gardener program. Anyway,I want them to learn the ingredients of a high quality compost;carbon materials, nitrogren materias, soil, air, and water.
What mnemonics would you use to teach them that carbon materials are dried leaves, dried grass, newspaper etc. and nitrogen materials are kitchen waste,green vegetable matter?
How would you explain to these young children the importance of composting? Also, what props would you use?
Thank you for your anticipated response.
