Locally Delicious The project outlined in this page is a small and Humboldt State Universities Engineering Design (215) class came up with a manageable worm bin design designed so that utilizes a small scale worm bin system kids ages eight to allow children of ages 8-12. The bin twelve can be constructed by kids recreate it, without the help of their parents , following the [[Locally_Delicious_Kids_Worm_Bin_inst|instructions we developed]]. This Giving a child the opportunity to build a worm bin enables kids 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 final design consists outlined below is a product of small water-resistant milk cartons that are easily accessible[[Onycophora]], recycled, and cheapa group of the Introduction to Design [[Engr215]] students.
[[Locally Delicious ]] is an organization run through based in Humboldt County, California, designed with a commitment to better the community as well as raise raising awareness on certain issues. The design of the Kids only worm bin is a branch importance of this group's work with community and sustainable living. [[Locally Delicious]] and Humboldt State University's Engineering 215 students, designing sustainable and easily reproducible project for [[Engr215 Introduction to Design]] class collaborated on a system series of schools projects in the areaSpring of 2011. After These projects are geared to help raise awareness of the projects have been finished importance of living and releasedeating healthy, material regarding the details of the various projects especially among children, and will be published as a compilation in a Locally Delicious' upcoming book tentatively due out , "Lunch box Envy."The worm bin described in this page was engineered by the fall Engineering 215 design team Onycophora. The "Wormland" worm bin is specifically designed for children ages eight to twelve, and therefore follows a unique set of 2011considerations. In the design of this bin size, cost, and the ability of the child were all taken into account. The final design outlined below is a product consists of Onycophoravarious materials found in every home and drugstore. Old milk cartons and tape make up the design, and scissors and a group pencil are the only tools required for assembly. The finished design will be able to process roughly a handful of the aforementioned Engineering 215 studentsorganic material per week with proper maintenance, as described in our building instructions.  ==Problem Statement and Criteria== The problem statement addressed by the "Wormland" bin project was to engineer a small and manageable worm bin that can be recreated and used by children between the ages of 8 and 12 years old based on the criteria==of Locally Delicious. A table further discussing our criteria is outlined below.  {| class="wikitablesortable" style="border:#A3BFA3; background:#F5FFF5"|-style="text-align:center; font-weight:bold; background:#CEF2CE;"! | Criteria! | Weights! | Description

| The design ability of children, age 8-12 years old, to reproduce the worm bin will be easily reproducible by the targeted age group, given adequate parental help and supervision.
==Description of final project==
Our Project The design is composed of empty half gallon milk or juice cartons.===Photos 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 descriptions===leave castings behind. Each time the food is digested new bedding is inserted. In addition, this [[File:Example.jpgLocally_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.
{{Gallery|width=350|height=375|lines=2|align=right|File:Cost_breakdown_ony1.png|Breakdown of the materials needed and associated costs.}}Our cost was very minimal because most the materials were recycled reused materials, this is a 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.
==Testing Results==
To test the cardboard milk/silk/juice carton worm bin, we placed a cut off strip of the carton in a glass of water. This test was meant to determine how well the material of the carton would react to extreme weather conditions over a period of time when cut. We also placed a cut up strip of the carton which we had taped back together in the glass of water to determine how well the tape would hold up. After leaving both tests in the glass of water for two weeks now, the strips of carton and tape have taken on little to no damage. Because of these promising results, we have determined that cardboard milk, silk, or juice cartons are a good material to use for the Kids Worm Bin design.
==How to build==
Steps to Making a Cooler Worm Bin
# Get a Styrofoam cooler the size you would like your worm bin to be. Be sure it also has a lid
# Put 10-12 holes in the top of the cooler lid with a pencil, stick, or pen.
# Flip lid over and remove any crumbs of foam left from punching the holes
# Poke more holes in the bottom side of the cooler for drainage.
# Shred newspaper (unlamented) into thin strips and make a pile.
# Place pile in cooler to around the half way point, if not high enough shread some more until its half full.
# Sparingly wet the newspaper (be sure to stir the newspaper to get the paper at the bottom wet)
# Add some dirt and dead plant matter to get the bin started
# Let sit for **insert time here**
# Add worms
# ……..
# Profit?

==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 soy milk or cow milk 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----

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.  Once implemented, it would therefore be important to take into account--------not only age and ability but adult supervision and help. Though this is a kid's project, it is recommended an adult assists with implementation and instructions to ensure proper building and safety. The next steps of the project will be the publishing of the designs and findings in the book compiled by the organization Locally Delicious, and its implementation by students. We hope that anyone who attempts this project is satisfied with their results and learns something about red worms and waste in the process.
The next steps of the project will be the publishing of the designs and findings in the book compiled by the organization Locally Delicious, and the implementation for students. It will be interesting see what new innovations are made with school byproducts.
