Eight steps are outlined for presenting a combined science/language experience unit to primary students, in which the children observe and discuss a phenomenon and dictate a group report. Sample projects with fossils, magnets, and air pressure are described. (SJL)

Describes, using "nonorthogonal" displacement functions, the normal-mode motions of a massive particle and a spring of non-negligible mass to whose end the particle is attached. The results lead to the complete solution for the general motion of the spring-plus-particle system. Shows that the presence/absence of gravity is irrelevant to the…

Describes a simple experiment for measuring the speed of sound using a partially filled beer bottle as a resonator. Outlines and discusses the approximations made in arriving at the procedure. (GA)

A demonstration is described that encourages students to engage in inquiry in biology. Using chemicals and an overhead projector, the instructor can simulate a living organism projected onto a screen. The reaction can aid students in defining the characteristics of life. (SA)

Ideas related to including ethology in high school biology programs are given. The methods of ethology and tips on how to communicate observations are briefly explained. (SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes how a Malaysian University has presented electronics and the laboratory work as a forced component in physics curriculum. (HM)

Described is an advanced undergraduate laboratory experiment in which radio-frequency transitions between molecular hyperfine structure states may be observed. Aspects of the quantum theory applied to the analysis of this physical system, are discussed. (Authors/BT)

This experiment is intended as a classroom demonstration. It describes the preparation of materials, the procedure, and a few remarks related to demonstrating travelling waves of chemical activity in the Zaikin-Zhabotinskii-Winfree Reagent. (SA)

Results of this study indicate that students' attitudes toward styles of painting studied were influenced in a positive direction through use of an experimental curriculum. (RW)

Describes a basic introductory chemistry experiment for science majors which departs from synthesis and moves instead into the realm of formulation. As part of a project that reorganizes the introductory chemistry sequence according to subjects with which students are acquainted, this laboratory makes use of oxidation-reduction chemistry to make…

Recommends a constructivist approach to physics laboratory activities to make laboratories a place for personal maturation and cognitive growth. Describes class design in which ideas and techniques are exchanged which allow students the opportunity to initiate investigations based on early conceptual assumptions, and extend the investigation…

Describes how a jigsaw cooperative learning structure divides lab work in a constructive, efficient way and provides a mechanism for sharing information. Pre-lab lectures are replaced with focused student discussions about the lab exercises. Students become more involved with the lab exercises, take responsibility for their own learning, and are…

Describes a titrator system, constructed from a computer-interfaced pH-meter, that was designed to increase student involvement in the process. Combines automatic data collection with real-time graphical display and interactive controls to focus attention on the process rather than on bits of data. Improves understanding of concepts and…

Describes a course specifically designed to allay the fear of science in elementary teachers by teaching them science in a laboratory-activity setting. Provides valuable laboratory experience often lacking in general education science courses. Lists topics covered in guided discovery exercises. Contains 12 references. (JRH)

Describes the use of videotapes to introduce experiments in a first-year undergraduate physics laboratory and investigates the effects on students' attitudes and achievement. Concludes that students responded positively to the video introductions but student performance was not improved. Discusses other positive outcomes of the videos. Contains 12…
