This packet is one of the "Exploration" series of curriculum materials developed for junior high and middle school industrial educators. The Exploration Series is intended to help them provide seventh- and eighth-grade students an opportunity to explore a wide range of industrial situations as well as some of the technologies used in the industry. The documents may also serve as a resource for teachers orienting ninth- and tenth-grade students to the industrial technologies of communication, production, energy utilization, and transportation and the impact of industry and technology. This packet is one unit in the area of the impact of industry and technology. It includes a rationale, hints to the teacher, lesson plans for two lessons (objectives, lesson content, and learning activities), student handouts for each lesson, teacher aids for the lessons, a unit examination, and a list of references. The lesson topics are recycling materials and evaluation. (YLB)
