A simple demonstration that is occasionally used in the classroom to show that light carries momentum involves making an orchestral cymbal audibly ring using light from a common photoflash. A metal plate or a piece of foil can also be used; however, it appears that many people use a cymbal because the sound is easily heard at a reasonable…

Achievement in primary school science courses has always been a field of interest by researchers in Turkey and other countries. For this reason, studies are conducted on science teaching at the primary school level. This study aimed to examine strengths and weaknesses of pre- and in-service primary teachers in science teaching. In addition, to…

Virtual Labs (VLAB) is a multi-institutional Open Educational Resources (OER) initiative, exclusively focused on lab experiments for engineering education. This project envisages building a large OER repository, containing over 1650 virtual experiments mapped to the engineering curriculum. The introduction of VLAB is a paradigm shift in an…

Teaching collections are of great importance for science instruction at any level. There are several problems linked to the handling and curatorial management of this kind of collection. Among these is the relatively short life-span of specimens, due to the damage from continuous handling by students. Often the specimens used to replenish the…

This paper presents low-cost experiments for a control systems laboratory module that is worth one and a third credits. The experiments are organized around the microcontroller-based control of a permanent magnet dc motor. The experimental setups were built in-house. Except for the operating system, the software used is primarily freeware or free…

This paper outlines a project for developing a comprehensive volume devoted to concrete teaching ideas, resources, strategies, and activities relating to science education for elementary school students and teachers. An extensive bibliography of existing references on science activities and resources is included. (SL)

This book consists of four sections: (1) "Supplemental Materials"; (2) "Supplemental Investigations"; (3) "Test Item Bank"; and (4) "Blackline Masters." The first section provides additional background material related to selected chapters and investigations in the student book. Included are a periodic table…

Describes methods to redevelop lab activities for use in schools with limited resources for proper facilities and equipment. Discusses take-home labs, paper-and-pencil labs, and lab station activities. (JRH)

Discusses the controversy about the discovery of element 72, involving Urbain's isolation of celtium, Dauvillier's reexamination of celtium samples, and Coster and Hevesy's announcement of the existence of hafnium. Indicates that the Copenhagen workers are finally accredited for the element discovery in their x-ray spectral studies. (CC)

During the 1994-95 school year, the Eisenhower Regional Consortium for Mathematics and Science Education at Appalachia Educational Laboratory (AEL) conducted the Scope It Out project to provide training and technical assistance to educators in using the microscope as a learning tool in a standards-based curriculum. This publication is a…

Describes the method to use in collecting freshwater algae for study in the classroom. Equipment lists are given as well as several illustrations. (SA)

Briefly describes 30 filmstrips in a series entitled "Experiments in Chemistry," suggested for use in lieu of a laboratory manual. (CS)

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…

Summarizes ideas for new demonstrations, experiments, and science-in-society topics for teaching chemistry. (WRM)
