Volume Two of the three-volume experimental program in general science attempts to provide preparation for the new approaches in biology, chemistry, and physics and to give those who will not continue in science a realistic way of understanding themselves, the world, and the role of science in society. Chapters on classification, heredity, light,…

Volume Three of the three-volume experimental program in general science attempts to provide preparation for the new approaches in biology, chemistry, and physics and to give those who will not continue in science a realistic way of understanding themselves, the world, and the role of science in society. Chapters on embryology, the body systems,…

The core portion of this trial unit prepared by the Australian Science Education Project provides an introduction to the structure of the earth, volcanic activity, the types of igneous rocks, earthquakes, and seismology, with an emphasis on the techniques of inference used to relate external evidence to internal structure. The optional activities…

Content, readability, safety aspects, appearance, technique, effectiveness of experiments, enrichment exercises, teacher aids, and special features of 12 physics laboratory manuals are reported and compared. (JN)

THIS LABORATORY MANUAL, THE COMPANION VOLUME TO THE STUDENT'S TEXT FOR THE "MAN MADE WORLD" HIGH SCHOOL COURSE, CONTAINS 31 EXPERIMENTS DEALING WITH THE THEORY, CIRCUITRY, AND OPERATION OF COMPUTERS, AND RELATED TECHNOLOGY. THE COURSE WAS WRITTEN BY SCIENTISTS, ENGINEERS, AND EDUCATORS, AND IS INTENDED AS A PART OF THE CULTURAL CURRICULUM FOR ALL…

This publication provides twelve model spacecraft construction plans for use by secondary school teachers in industrial arts classes. These models were adopted and developed from plans supplied by the National Aeronautics and Space Administration and are representative selections from the many spacecraft used in space exploration programs. Some…

A preliminary version of this trial draft of a unit prepared for Australian secondary science students was previously announced as ED 049 931 under the short title of "Messengers." The teachers' guide is an overprinted version of the students' booklet, and lists objectives for each section of the materials, indicates possible teaching…

An alternative method of bacterial spore staining using malachite green is described. This technique is designed to save time and expense by a less messy procedure. Advantages and adaptations of the technique are also given. (MR)

Describes a unit of study of microorganisms employed with great success by over 100 teachers. The guide is a laboratory manual containing no prodedures or instructions. Only a brief problem statement is included. The student is the researcher and works out his own questions, procedures, results, and observations. (DF)

The purpose of this instructional unit is to convey an understanding of the part played by effective problem definition and hypothesis statement in the solution of scientific problems. The major concepts of the unit are process rather than content oriented. Problems, hypotheses, variables, constants and controls represent the principal concepts…

Nine experiments and 17 activities are presented in this handbook. The experiments are related to the earth's size and orbit, Piton height, telescope operations, Mars and Mercury orbits, stepwise approximation, and models of comet orbits. Further naked-eye observations in astronomy are designed in connection with the sun, moon, and planet…

This field studies manual, developed by biology students in the 1971 Georgia Governor's Honors Program, was designed for collection of data pertinent to freshwater and estuarine habitats. In addition to the various methods of sampling the ecosystem and for quantification of the data, instructions for dividing the field study into three logical…

This volume is the teacher's edition of the student record book to be used with the seventh grade text "Probing The Natural World." The record book is divided into two sections. The first provides both spaces for answers to the questions asked in the text and the necessary data tables for the activities. The questions asked in the text…

Nuffield Combined Science, prepared for the first two years of British secondary schools (grades seven and eight, approximately), is described in SE 015 449. Teachers' Guide II and Activities Pack II contain the material developed for the following sections: Water; Small Things (microorganisms and particle theory of matter); Earth; Insects; and…

This UNESCO newsletter is divided into these three sections: (1) a student chapter on the rates of chemical reactions; (2) the student laboratory guide; and (3) the teacher laboratory guide. The laboratory guides describe 14 experiments showing students the differences in chemical reactions and how the rate can be affected by temperature,…
