Extensions to the learning cycle are provided. The kit contains a teacher guide, six packets of labeled recycled plastic pellets, four products in the steps for the construction of recycled plastic wood, and a preformed two liter bottle. The teacher guide contains background information for the teacher and students, learning cycle activities, and activity extensions. In one of the kit's activities, students identify the six kinds of recycled plastic by measuring their physical and chemical properties. The students perform diagnostic tests, such as exposing the samples to acetone, heat, and oil.
Students compare their results to a flowchart in order to identify the different types of plastic.
As an extension activity, students search for the resin code on various containers at school, home, and the supermarket. Teacher tips and student directions are accompanied in the teacher guide by flow charts, data sheets, and assessment forms. The contact information for state recycling offices is provided.
