One of a series of eleven curriculum manuals which cover the four transportation topics of public transportation, transportation and the environment, transportation safety, and bicycles for elementary, secondary, and adult levels, this manual covers the transportation and the environment topic for grades 9-12. It contains forty-four learning activities grouped into eight mini-units. Each mini-unit consists of a lesson plan component and an individual learning activities component. The first mini-unit provides a survey of issues related to transportation and the environment; the rest are as follows: learning about the interrelationships between transportation and the environment, learning about the automobile's effects on the environment, identifying solutions to conflicts between transportation and the environment, taking personal actions to resolve conflicts between transportation and the environment, examining the theory of and engaging in citizen participation to resolve conflicts between transportation and the environment, and researching issues related to transportation and the environment. A final section offers additional activities that may be used to evaluate or supplement evaluation of an activity or mini-unit. Also included are references for further study resources and masters for reproduction of role profiles, game boards, maps, and other distributable materials. (A curriculum guide, CE 014 028, is also available for use with the manuals.) (TA)
