Parts I and II of the students' guide to the three-year integrated biology, chemistry, and physics course being prepared by the Portland Project Committee are contained in this guide. A committee reviewed and selected material developed by the national course improvement groups--Physical Science Study Committee, Chemical Bond Approach, Chemical Education Materials Study, Biological Science Curriculum Study and Introductory Physical Science--and added material written especially for the project. This material was fitted into a previously prepared course outline which endeavored to match students' abilities, interests, and maturity level with the level of sophistication of the concepts. This course was to be taught for the first time in eight Oregon schools in the 1967-68 academic year. This guide contains Part I, "Perception and Quantification" and Part II, "Properties of Matter." These themes are developed through student-centered activities. A table relates the student activity to the most pertinent text reference or suitable film. (GR)
