The field tested fifth grade unit was designed to develop the learner's awareness of the components of the world of work, both individually and collectively through classroom simulations. The six lessons cover physical demands, physical demands and the world of work, environmental working conditions, working conditions and the world of work, physically hazardous working conditions, and the worker's world.

Each lesson is presented under the headings of: concept, performance objectives, new vocabulary introduced, resources required, instructor preparation tasks, instructional procedures (introduction, tasks, summary), assessment procedures and tools, and worksheets. An instructional strategy guide covering demonstrations, discussions, and questioning; supplementary activities for lesson 2 and a five-item bibliography are appended. (BP)
