[[Locally Delicious]] is an organization based in Humboldt County with a commitment to raising awareness of the importance of community and sustainable living. [[Locally Delicious]] and Humboldt State University's [[Engr215 Introduction to Design]] class collaborated on a series of projects in the Spring of 2011. These projects are geared to help raise awareness of the importance of living and eating healthy, especially among children, and will be published in Locally Delicious' upcoming book, "Lunch box Envy." The design outlined in this page is a worm bin designed for kids ages eight to twelve constructed by the Engineering 215 design team Onycophora. The design of the worm bin fills Onychophora’s objectives of engineering a small and manageable worm bin that can be recreated and used by children between the ages of 8 and 12 years old.
The bin can be constructed by kids without the help of their parents following the [[Locally_Delicious_Kids_Worm_Bin_inst|instructions we developed]]. Giving a child the opportunity to build a worm bin enables them to get hands-on experience with composting and sustainable living, and allows them to see waste transformed into something useful!
After the projects have been finished and released, material regarding the details of the various projects will be compiled and published tentatively due out Fall 2011. The design outlined below is a product of [[Onycophora]], a group of the Introduction to Design [[Engr215]] students.

The "Wormland" worm bin is specifically designed for children ages eight to twelve, and therefore follows a unique set of considerations. In the design of this bin size, cost, and the ability of the child were all taken into account. The final design consists of various materials found in every home and drugstore. Old milk cartons and tape make up the design, and scissors and a pencil are the only tools required for assembly. The finished design will be able to process roughly a handful of organic material per week with proper maintenance, as described in our building instructions.
== Problem Statement and Criteria==
==Description of final project==
Our design is composed of empty half gallon milk or juice cartons. Inside of the cartons is a migration hole that allows worms the access to both cartons. Worms are fed on one side of the bin while castings can be removed from the other carton. This process will be repeated as the worms will migrate towards the food and leave castings behind. Each time the food is digested new bedding is inserted. In addition, this [[Locally_Delicious_Kids_Worm_Bin_inst#Modular_Design|modular design]] allows for expansion of the worm bin to meet the needs for digestion of larger quantities of food.

Our cost was very minimal because most the materials were reused materials, the table to the right shows of our costs and total for the project. The worms are the highest expense for the project. The total cost of the project was free. The project had worms donated from another worm bin. The total cost of the project without donations is less than twenty dollars.

==Discussion and next steps==
The overall design of the kid's worm bin is such a simple one that it allows for various small changes of material and location. The "bin" itself could be constructed of any waterproof, easily accessible material, not just milk or juice cartons. The design works well both inside and outside, and can be easily placed in any area due to its small size. Though working for a variety of ages, testing results led us to believe that children eight to twelve years of age will be fully capable of building a "Wormland" bin if provided with adequate instruction.
