Vermicomposting

Worms with an Appetite (for Waste)! 

Ages: 6 and up

Group Size: Up to 60

Duration: 45 minutes to 1 hour (adaptable to grade-appropriate length)

Description: 
This presentation begins with a discussion about what we do with our waste. The presenter speaks about how the variety of trash items we create will go into different containers. Students are then asked how and what they recycle and are introduced to the concept of composting. This discussion leads into an examination of nature’s recyclers…the “red wiggler”. Red wigglers–also called redworms, or “Eisenia foetida”–are the primary worms used for vermicomposting (composting with worms). Students will learn a bit about the physical structure of this tiny biological wonder, understand the role “red wigglers” play in the environment (and in recycling leftover food waste), and investigate the concepts of waste reduction and recycling. A hands-on demonstration of how to prepare, maintain and harvest a worm bin concludes the lesson. Each student gets to create their very own worm bin to take home and is instructed on how to take care of it to produce optimum compost results.  All necessary materials are provided by the YCSWA.

Evaluation Tool
Students will be able to describe the basics of trash disposal, recycling, and composing. They should understand the environmental benefits of vermicomposting, and relate how vermicompost is used to enhance soil nutrient value for plants.
