The major ideas of this unit are: consistency and uniformity, cause and effect, and parsimony. Laboratory experiences consist of investigations into: projecting expectations, moon and stars, the relationships among different kinds of change (daily, monthly, annual temperature changes), force and motion, chemical reactions, superstitions, origin of…

The major ideas of the unit are: normal curves, gradients, extrapolation and interpolation, directional change, cyclic change, and dynamic equilibrium. Some 28 different inquiry-oriented laboratory experiences are designed to develop understanding of these major ideas. The laboratory experience format is as follows: Introduction, Materials and…

The major idea of the unit is: a scientist thinks in terms of relationships rather than absolutes. Twenty-nine inquiry oriented laboratory experiences are arranged under the headings: (1) measurements express relationships, (2) patterns govern relationships, (3) frames of reference determine relationships, (4) heredity and environment are…

Twenty-four activities suitable for outdoor use by elementary school children are outlined. Activities designed to make children aware of their environment include soil painting, burr collecting, insect and pond water collecting, studies of insect galls and field mice, succession studies, and a model of natural selection using dyed toothpicks. A…

This volume is the first in a series of the ACS "Modern Chemical Technology" (ChemTeC) curriculum which is to prepare chemical technicians. The chapters concentrate on gas chromatography, tests for purity, properties of gases, and gas measurements. Included is the appropriate content, exercises, laboratory activities, and all needed mathematics.…

Presented are five procedures which permit the effective teaching of chromatography with equipment which is readily available, economical, and simple in design. The first procedure involves a study of solute partition in two immiscible solvents and of countercurrent distribution. The second illustrates the use of unidimensional ascending paper…

The Grade 7 Science course of study was prepared in two parallel forms. A short form designed for students who had achieved a high measure of success in previous science courses; the long form for those who have not been able to maintain the pace. Both forms contain similar content. The Grade 7 guide is the first in a three-year sequence for…

Contained are instructional materials developed by the Science Project Related to Upgrading Conservation Education ("SPRUCE"). It is designed for use with the SPRUCE "Discovery Box" and contains twenty-one sets of investigations based on the twenty-one packets of specimens in the box; three sets are recommended for each of…

The author describes a comprehensive science program for the elementary school. The program should include six components: (1) The story of the great generalizing constructs of science, such as the atom, the universe, the layers of the earth, and evolution--even though the students do not have the observational evidence to support the constructs;…

Included are two of the eight units of the Intermediate Science Curriculum Study materials designed for grade nine students. These are "investigating variation" and "winds and weather." Introductory notes to the student explain how the book is to be used. Each chapter starts with a short statement of a general problem, then…

Information about the insect world and its advantages for the elementary classroom teacher is given in this paper, along with activities which can teach students about insects. The insect world tends to be noticed by the average person only when the small creatures become pests or inhabit man's abode. However, young students have a sharp sense of…

The unit presented in this teacher's guide is the first of two developed for the fifth year in the Science Curriculum Improvement Study (SCIS) curriculum. Attention is focused on energy transfers involved in the interaction of matter in solid, liquid, and gaseous forms. The chapters are presented in six parts which include activities for reviewing…

This volume is the first of a three volume, one year program for use in junior high school, and consists of these three units: Environmental Science, Crusty Problems (earth science), and Why You're You (heredity). The environmental science unit is composed of chapters relating to these subjects: the black death (plague); energy, food chain, and…

Space science-oriented concepts and suggested activities are presented for intermediate grade teachers of science and mathematics in a book designed to help bring applications of space-oriented mathematics into the classroom. Concepts and activities are considered in these areas: methods of keeping time (historically); measurement as related to…

Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the first volume of a two volume, one year program in physical science, and contains these five units and activities: First Class Levers, six activities; Inclined Plane, six activities; The…
