The two student notebooks in this set provide the basic course outline and assignments for the second year of a four year senior high school unified science program. The two volumes contain these four units: Expansion of Ideas About the Nature of Matter, Characteristics of Living Matter, Mechanisms of Life Processes, and Patterns of Change. The major portion of the first unit is devoted to basic chemistry; and the unit on patterns of change involves lessons and activities in heredity, population dynamics, and evolution. The materials in the notebook for each of the sub-units include: a list of required and recommended readings from various other books; questions for consideration in introducing a lesson; a brief background reading; a basic outline of the lectures with space provided within the outline for notes; laboratory activities and investigations; laboratory problem reports and other kinds of assignments (discussion questions, completion questions, problems); and summary statements and review questions. Numerous diagrams and illustrations are included. (PR)
