Describes the displays, research activities, and educational aspects of San Francisco's Steinhart Aquarium. (SL)

Discusses activities for field trips to study tidal pools, particularly along the Northern Gulf of California and the Pacific Coast of California. (SL)

Explains the inertia ball demonstration qualitatively. For the advanced level the demonstration is treated as a forced harmonic oscillator and the results verified analytically. Computer-generated graphs show that with a rapid pull, the upper cord may break, or the upper and lower cords may break simultaneously. (Author/GA)

The work output of a human body in various tasks and the biochemistry of oxygen consumption in muscles is discussed. (CP)

Describes how a thermosyphoning solar water heater capable of heating 110 kilogram of water to 80 degree Celsius and maintaining this temperature for 24 hours was constructed by four students in the fifth form of Sekolah Date Abdul Razak, Seremban, Malaysia in 1976. (HM)

After briefly reviewing equations of conduction and diffusion, and voltage and charge in electrical circuits, a simple experiment is given that allows students practical experience in a theoretical realm of physics. (MDR)

Describes the construction and use of a simple apparatus to measure the magnetization density and magnetic susceptibility of ferromagnetic, paramagnetic, and the diamagnetic solids and liquids. (Author/GA)

Principles, experimental procedures, results, and discussion of this method are included here. The method was used in undergraduate laboratory courses in Toulouse, France. (BB)

Describes the construction of a simple beam model of the hydrogen atom. (SL)

Describes an experiment illustrating the absorption in the ultraviolet region to provide a simple spectrometric analytical method. (SL)

Contains the contents of the Student Investigation booklet of a Crustal Evolution Education Project (CEEP) instructional modules on earthquakes. Includes objectives, procedures, illustrations, worksheets, and summary questions. (MA)

Describes the apparatus and procedures for conducting an experiment to measure the relative brightness and degree of polarization of the sky. (SL)

Discusses using the teaching technique of requiring students to describe what will happen prior to conducting demonstrations and experiments. (SL)

The basic physical principles of dye lasers are discussed and used to analyze the design and operation of tunable dye lasers pumped by pulsed nitrogen lasers. Details of the design and construction of these dye lasers are presented. Some simple demonstration experiments are described. (BB)

Describes the contents of Elementary School Aerospace Activities: A Resource for Teachers. Activities examine a variety of topics in aerospace education and are intended to be used with children ages 5-11. The book is available from the Government Printing Office (GPO) for $3.00. (CP)
