Presents two scenarios to illustrate the difference between liability and negligence. Also presents highlights of four actual cases related to laboratory security, appropriate facilities, proper instructions, and protective gear. (JN)

Describes an experimental model for preservice and inservice programs for elementary teachers based on the collaborative efforts of a county school system and a university. Explains program components and highlights the benefits that have resulted from this type of approach. (ML)

Offers suggestions for the development of a laboratory assistant program. Includes guidelines and factors to consider in the selection process and in the training program. Discusses the advantages of this type of program for both students and teachers. (ML)

Presents a set of laboratory experiments that can assist students in the detection of carbon dioxide. Offers a variation of the supported drop method of carbon dioxide detection that provides readily visible positive results. Includes background information on carbon dioxide. (ML)

Explains how computer and game port interfacing reduces the time required for data collection and organization and also stimulates student interest in science laboratory exercises. Illustrates this approach through a description of a population-variation lab. Includes diagrams for the construction of the interface box. (ML)

Provides an overview of the Roswell Park Memorial Institute Summer Science Program for high ability students with strong scientific and mathematical backgrounds. Discusses the participants perceptions of the benefits of this program and reports data related to participants' college majors. (ML)

Describes procedures for examining a beetle's anatomy with microsurgical tools. Instructions for experimental exercises dealing with the insect's structure and digestive enzymes are outlined. Tips on how to make a microscalpel are also included. (TW)

Discusses the use of remote sensing from satellites to monitor glaciers. Discusses efforts to use remote sensing satellites of the Landsat series for examining the global distribution, mass, balance, movements, and dynamics of the world's glaciers. Includes several Landsat images of various glaciers. (TW)

Describes a 50-minute session designed to improve students' writing of science laboratory reports. Using an improperly worded description of how to make a peanut butter sandwich, the students work in groups to improve "point of view" and "voice." The changes are then used to create better reports. (TW)

Discusses the need for quality computer software for science instruction. Argues that very little software is currently available that uses the computer's capabilities to provide quality science instruction. Describes microcomputer tutoring systems under development at the University of Pittsburgh that are intended to significantly add to the…

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)

Describes how students can construct kaleidoscopes to learn basic principles of reflection. Instructions are included for simple experiments using mirrors. Outlines more complicated constructions of kaleidoscopes with recommendations for variations of the experiments. (TW)

Describes several ways to build data collection devices for microcomputers. The interface devices connect with either the computer's game port or an analog-to-digital converter. Discusses how teachers have designed the equipment and appropriate software to use with the computer in biology teaching. (TW)

Describes the development of a 29-point questionnaire regarding safety in the science laboratory. Includes a copy of the questionnaire along with specific recommendations for action to take relating to each item on the questionnaire. (TW)

Provides ideas for using the same port connection of personal computers to interface with laboratory instruments. Contains specific instructions on how to build transducers. Includes plans and diagrams for thermistors and light meters as well as computer programs for displaying instrument readings on monitors. (TW)
