Discusses how the concept of organoleptic chemistry permeates every modern chemical experiment. Six approaches for developing organoleptic attitudes which are crucial to the experimental aspects are also presented. (HM)

Compares between the component and the modules (system) approaches which are used to teach electronics at Croydon High School, Australia. The author presents some personal views from his experience of teaching both ways. (HM)

Discusses the use of toys to teach physics. Potential advantages and disadvantages of using toys in the physics classroom or laboratory in addition to some demonstrations and experiments that use balls, cars, and musical toys are also presented. (HM)

The experiments described in this article discuss the versatility of the linear variation method in quantum chemistry and the ease with which it can be used with a simple computer program. (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)

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 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…

Describes an investigation of the associations between students' perceptions of laboratory environment and their attitudinal, cognitive, and practical performance outcomes. Assesses student outcomes in three distinct areas: (1) student attitudes; (2) achievement on a written examination; and (3) practical performance, specifically in the biology…

Describes the use of mud dauber wasp nests in laboratory activities in ecology and behavior and life science classes. Provides students with an opportunity to develop and practice basic skills including dissection, identification, observation, measurement, and communication. Discusses the life of mud daubers, obtaining and storing nests,…

This article lists 23 comprehensive Web sites related to providing differentiated instruction to gifted students. It also discusses overall areas of differentiation, including modifying content, altering the pace of instruction, creating a flexible classroom environment, and using specific instructional strategies. Science instruction Web sites…

Discussed are the procedures and results involved in this activity. Student results in undergraduate laboratories indicate high quality results and relative ease of the analysis. (CW)

Shows that the mutual repulsion that enables a superconductor to levitate a magnet and a magnet to levitate a superconductor can be combined into a single demonstration. Uses an overhead projector, two pellets of "1-2-3" superconductor, Nd-Fe-B magnets, liquid nitrogen, and paraffin. Offers superconductor preparation, hazards, and disposal…

Described is a laboratory procedure for teaching seed stratification. Materials, methods, results, and applicability of the experiment are explained. Diagrams showing the percent of total germination as a function of stratification time and the germination rate of stratified seeds are included. (RT)

Presents an overview of coatings along with paint preparation labs. Provides students with information about and methods for preparing a product that is an integral part of daily life. Gives methodology which can be used to prepare oil based and water based paints. (MVL)

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)
