Describes a technique to improve the adaptation, development, and utilization of laboratory worksheets. Two sample worksheets (on decomposition of ethanol and on solubility of potassium chloride) are included. (JN)

Discussed are the construction and uses of a version of a photoelectric colorimeter by students. Included are materials needed and four experiments which use the equipment. Sample results are shown. (CW)

Discussed is the conceptualization, development, and formative evaluation of a series of science education videodiscs. The formative data indicated that videodisc programs can enhance the effectiveness of teachers and substantively impact student achievement and attitudes. (Author/CW)

Describes the "Project 1-2-3" levitation kit used to demonstrate superconductivity. Summarizes the materials included in the kit. Discusses the effect demonstrated and gives details on how to obtain kits. Gives an overview of the documentation that is included. (CW)

Describes an accurate system for measuring speeds and frequencies with a microcomputer. Explains how the system can give a reasonable graphical representation of velocity and acceleration against time. Gives examples of graphs produced by the program and provides an address to obtain the software for their application. (CW)

Describes efforts of members of the biology and physics departments of Paisley College (Scotland) to develop a simple light-emitter-detector arrangement adapted as a colorimeter interfaced with a microcomputer for use by undergraduate students. Discusses the setup and provides a computer program in BASIC to run it. (CW)

Describes an open-ended computer simulation project that can be used to illustrate the growth of solid crystals in different forms at any level from high school physics to graduate physics. Discusses a simple computer program in BASIC language on an IBM personal computer. Gives examples of simulations. (CW)

Illustrates ways in which science activities that utilize culturally familiar materials can help bilingual students gain insight into the scientific concepts which underlie the functioning of cultural artifacts and tools. Specifically indicates how nine categories of materials familiar to Chinese and Hispanic cultures can be used in science…

There are ways in which elementary teachers in general and rural elementary teachers in particular can overcome inadequate science preparation and can upgrade the science program resources of their small schools. Parents and children should be involved in obtaining free and inexpensive science-related materials throughout the year. These can be…
