Thirteen experiments and 15 activities are presented in this unit handbook for student use. The experiment sections are concerned with naked-eye observation in astronomy, regularity and time, variations in data, uniform motion, gravitational acceleration, Galileo's experiments, Netson's laws, inertial and gravitational mass, trajectories, and…

Seven experiments and 40 activities are presented in this handbook. The experiments are related to Young's experiment, electric forces, forces on currents, electron-beam tubes, and wave modulation and communication. The activities are primarily concerned with aspects of scattered and polarized light, colors, image formation, lenses, cameras,…

Five experiments and 19 activities are presented in this Unit 5 handbook. The experiments are related to electrolysis, charge-to-mass ratio, elementary charge determination, photoelectric effects, and spectroscopic analyses. The activities are concerned with Dalton's theory, water electrolysis, periodic tables, single-electron plating, cloud…

Five experiments and nine activities are presented in this Unit 6 handbook. The experiments are related to random events, ranges of alpha and beta particles, half-lives, and radioactive tracers. The activities are concerned with the energy measurement in beta radiation, demonstration with sugar cubes, ionization by radioactivity, magnetic…

The study involved the development, implementation and evaluation of laboratory audio-tutorial activities in a college chemistry course. The activities were designed in a self-instructional mode, written as linear programs and taped instructions. A pretest was used in two instances, but all included a posttest. To evaluate the effectiveness of the…

Presented are the procedures, results, and conclusions of a study designed to compare the effectiveness of programed instructional materials with that of conventional materials in university physical science laboratory classes. The subjects were students enrolled in two similar freshmen-level physical science general education courses who were…

Included is a teachers resource collection of 42 marine science activities for high school students. Both the biological and the physical factors of the marine environment are investigated, including the study of tides, local currents, microscope measuring, beaches, turbidity, sea water solids, pH, and salinity, marine bacteriology, microbiology,…

The text of Volume 4 represents an international review of research in mental retardation dealing primarily with human and animal laboratory behavior. The contents range through the following topics: memory processes in retardates and normals by Norman Ellis; a theory of primary and secondary familial mental retardation by Arthur Jensen;…

Provided are biological science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments are directed at the student understanding the balance of chemical and physical processes which must be maintained in order to sustain life,…

Provided are physical science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments cover a limited number of topics representative of the scientific enterprise. Some of the topics are pressure and buoyancy, heat, motion,…

This laboratory manual, part of a series of instruction books on basic experimental chemistry, is designed to provide the secondary school students of developing countries in Asia with laboratory experiences that bring out the fundamental concepts and ideas of chemical kinetics. Taking into consideration the possibility of limited facilities of…

The primary purpose of this study was to determine if self-instructional data analysis sessions could be used effectively as traditional college laboratories to reinforce students' understanding of certain principles of mechanics. The secondary purpose was to determine whether any of the 140 college physics students involved had a dependence on…

Designed for use in Pennsylvania secondary school science classes, this guide is intended to provide fundamental information in each of the various disciplines of the earth sciences. Some of the material contained in the guide is intended as background material for teachers. Five units are presented: The Earth, The Oceans, The Space Environment,…

Presented is a compilation of eight articles relating to science teaching in England, primarily at the secondary school level. An editorial describes recent changes in sciences and science education, decreased student enrollment in science courses, and increasing emphases on scientific methods training. The articles are then presented in three…

This publication is one of a series of single-topic problem modules designed for use in undergraduate geology and earth science courses. The first section, "Ain't It Flat? A Series of Experiments in Geodesy," presents various experiments for determining the earth's circumference (historically) and describes the use of satellites in determining the…
