Describes the use of a microcomputer-based laboratory (MBL) in teaching the concepts of heat and temperature to eighth grade students. Discusses the advantages of being able to instantly display the results of their experimentation with the use of temperature and light probes, and heat pulsors. (TW)

Contains abstracts of presented papers which deal with teaching materials and methods in physiology. Includes papers on preconceptual notions in physiology, somatosensory activity recorded in the dorsal root ganglion of the bull frog, and the use of the Apple Macintosh microcomputer in teaching human anatomy and physiology. (TW)

Discusses the importance of teaching about enzymes in chemistry. Mentions several applications of enzyme technology to other fields. Describes an experiment involving the immobilization of yeast cells as a biocatalyst for the ethanol production from glucose. Argues for more biotechnology to be integrated into basic chemistry courses. (TW)

Exploratorium Science Snacks are miniature versions of some of the most popular exhibits at the Exploratorium, San Francisco's (California) museum of science, art, and human perception. Nearly 100 teachers worked with Exploratorium staff members to create scaled-down versions of exhibits that teachers could make using common, inexpensive,…

Described are several activities for teaching children to determine mass and volume. Included are the masses of a water drop and a grain of rice; the volume of a water drop and small solids; and measuring the width of a hair. Procedures and materials for the activities are discussed. (CW)

Describes two simple methods of error analysis: (1) combining errors in the measured quantities; and (2) calculating the error or uncertainty in the slope of a straight-line graph. Discusses significance of the error in the comparison of experimental results with some known value. (MDH)

Presents a framework for teachers to use the thermodynamic system of popping corn to generate student interest. Examines the popping mechanism and the role of steam in, the heat required during, and the energy efficiency of the popping process. (MDH)

Describes an activity measuring the amount of dissolved carbon dioxide in carbonated water at different temperatures. The amount of carbon dioxide is measured by the amount of dilute ammonia solution needed to produce a pH indicator color change. (PR)

Describes four instructional techniques used to deliver specific developmental objectives in both an introductory chemistry course and a general course in science and technology. The four techniques described are miniresearch projects, scenario-based research projects, short essay examination questions, and issues-directed research project. (PR)

Describes using picture books and science activities in early childhood science instruction. Suggests titles of books and activities for the following topics: Time for Pets; Environmental Awareness; Dinosaurs Galore; Nighttime Science; Simple Machines; Insect Collections; Snowy Days; Water, Water, Everywhere; and Experimental Activities. (PR)

Because of the daily impact of biotechnology, it is important that students have some knowledge and experience with biotechnology in order to enable them to deal with the issues that arise as a result of its implementation. The purpose of this workbook is to assist in the efforts to expose students to the concepts of biotechnology through hands-on…

This document describes a general introductory course in applied science intended for students of various interests and abilities. The course is designed to provide high school students with a basic understanding of the space age with an emphasis on model rocketry. Included is an outline of the subject matter to be covered in units on: (1)…

Based upon the recognition that the sea has great potential as a future source of energy, minerals, and water, this document was developed to provide students with learning experiences in oceanography. It contains background information about ocean tides, waves, chemistry, depths, and plant and animal life. The book provides the teacher with…

Based on the idea that active participation stimulates the processes by which learning takes place, this document provides teachers and students with a variety of information and learning activities dealing with energy. Concepts about energy are presented through the use of laboratory experiments, demonstrations, worksheet exercises and individual…

Much of the innovation in the use of microcomputers in education has come from classroom teachers who are using computers with students. In October, 1987, forums were held for secondary school science teachers who were using computers in their science classes. Within this document are some of the lesson plans that the participating teachers…
