The purpose of this article is to provide college level physical geography and geology teachers with practical and simple techniques to help students classify and understand igneous, sedimentary, and metamorphic rocks. Essential equipment is also discussed, and recommended readings are listed. (RM)

This booklet presents some activities to measure various weather phenomena. Directions for constructing a weather station are included. Instruments including rain gauges, thermometers, wind vanes, wind speed devices, humidity devices, barometers, atmospheric observations, a dustfall jar, sticky-tape can, detection of gases in the air, and pH of…

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

Intended for the elementary teacher who lacks science teaching experience, this article presents tips for finding background information and for stocking a portable "science lab" with everyday materials. It also outlines 10 easy experiments. (SJL)

Summarizes some of the astronomy materials developed at the Lower North South Australian Science Teachers Association (SASTA) meeting of October, 1978. (HM)

Young children are naturally curious about their environment and learn best by exploring the world around them. Magnifiers, or hand lenses, are a valuable tool in this exploration. Discusses the selection, use, storage and costs of magnifiers. Includes suggestions of objects/phenomena to observe inside and outside of the classroom. (JN)

Presents three notes on new equipment, techniques, or materials of interest to teachers of physics. (HM)

Presents two demonstrations to compare the differences between the screen reproductions of a bulb when using a converging lens and a pinhole and how that reproduction image reaches the observer's eye from multiple vantage points. (MDH)

Reports the recommendations of the annual American Institute of Biological Sciences (AIBS) meeting at the University of Georgia. Suggests that biologists should become more involved in land use planning and resource allocation in the Southeast. Presents a seven-step process for land-use decision-making. (MA)

Describes a science education class developed for elementary school children who are blind, deaf, or emotionally disturbed. Lessons are designed to work equally well for physically handicapped, emotionally disturbed, and nonhandicapped children. Concepts include modified classroom equipment, development of independence, and the role of the teacher…

Provides instructions to build an inexpensive device to demonstrate wave-motion to elementary school children. (MDH)

Describes three accessories developed to be used in conjunction with the rotating platform or turntable. Three demonstrations using these accessories are included. These demonstrations are: (a) conservation of angular momentum; (b) gravity-defying goblets; and (c) direct measurement of centripetal force. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

Describes some simple solar energy experiments, reviews real life examples of solar energy, and lists areas where solar energy can fit into existing school science curricula. Instructions for making equipment needed, a discussion of recent developments in thermal systems and photovoltaics, and a bibliography are included. (JN)

Reports that although excitation at 337nm is less than optimal, detection limits in the range 1-100pg/ml were found. Provides a calibration curve and results for seven organic compounds. (MVL)
