By introducing a worm composting bin into your classroom, you not only support sustainability and good stewardship of the Earth, but you can incorporate lessons related to organisms, populations, and communities; the transfer of energy in the food web; decomposers; biotic and abiotic aspects of an ecosystem; stimuli and response; reproduction; symbiotic relationships; healthy soil; binomial nomenclature, and the list goes on. Finish the year with a very dynamic Worm Day!
