Discusses an activity in which computers with color monitors can be used to demonstrate light blending with relative ease. (MKR)

Describes a simple method to enhance the teaching of protein structures and function by analyzing amino acid sequences using word processing programs. (ZWH)

Presents five interactive, computer-based activities that mimic scientific tests used by sport researchers to help companies design high-performance athletic shoes, including impact tests, flexion tests, friction tests, video analysis, and computer modeling. Provides a platform for teachers to build connections between chemistry (polymer science),…

Presents activities using thermocouples to investigate the temperatures at which candles burn and popcorn pops. (MKR)

Presents an effective way to start a technological revolution in schools by beginning with a single exciting project that incorporates new technologies and then letting interest in the project prompt others to action. (JRH)

Describes methods to access current earthquake information from the National Earthquake Information Center. Enables students to build genuine learning experiences using real data from earthquakes that have recently occurred. (JRH)

In this presentation we will investigate the mathematics and physics of a free-falling object, not for the purpose of research to discover some profound physical phenomena, but rather to enhance students' ability to gather, organize, and analyze data using state of the art hand held technology. We will use the TI-83 plus (a sophisticated graphing…

Describes the use of weather satellites in providing an exciting, cohesive framework for students learning Earth and space science and in providing a hands-on approach to technology in the classroom. Discusses the history of weather satellites and classroom satellite tracking. (JRH)

Presents a method of calculating acceleration resulting from gravity using computer-controlled photogates. (ZWH)

Outlines benefits of integrating optical instruments in computer-based instructional systems in a science classroom including budget, immediacy, pictorial records, and graphic enhancement. Presents examples of investigative activities involving optical instruments and images digitized for computer-based manipulation. (JRH)

Describes how students in a geoscience course are introduced to geographic information systems (GIS), a computer-assisted system for the acquisition, storage, analysis, and display of geographic data, through a practical experience involving collecting data and inputting it into a GIS program called IDRISI. (MKR)

A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

This note describes an inexpensive means for making high resolution analog voltage measurements using the parallel printer port of a standard IBM PC or compatible. (PR)

Discusses a program in which students complete surveys identifying home energy and water use and its impact on the environment. Survey results are entered into computers lent to the school by a sponsoring utility company. Includes sample activities. (MKR)
