SCRAP Humboldt waste stream educational wheel
The Waste Stream Education Wheel was designed in the Humboldt State University Engineering 215 class to be an educational tool for use by SCRAP Humboldt. The wheel targets third through eighth graders, and teaches how three everyday objects go through the waste stream.
The client is SCRAP Humboldt (School Community Reuse Action Project), an up-cycling center based out of Humboldt County that implements education and affordable materials. This helps to promote their goal of environmentally sustainable behavior and creative reuse. In order to promote their values to the public, they seek a tool that they can use in their facility for educating the youth about the waste stream.

Description of final project
The Waste Stream Education Wheel is an educational tool that teaches children about the waste stream. Its main focus is on three primary items: a gaming device, an aluminum can, and a t-shirt. When the wheel is spun, the viewing window reveals each step in the life cycle of the primary item seen on the wheel. The board is interactive, and will help kinesthetic as well as visual type learners. The frame of the structure is made of bamboo. Two of the wheels are made of plexiglass, while the third wheel is made of an upcycled record. The knobs are upcycled as well.
SCRAP Humboldt and local businesses donated many materials. The retail cost is based on prices from local stores.

How to build
The Waste Stream Education Wheel consists of three wheels fashioned out of plexiglass and a vinyl record. They are connected to a plywood backing with a bamboo frame for additional support. Each wheel has an up-cycled cabinet knob used to spin the wheels independently. A cut is made on each wheel for a viewing window to display information corresponding to each waste stream item.
