Why Does It Take Longer to Boil Potatoes at High Altitudes? This column provides background science information for elementary teachers. This month's issue looks at why water boils at different temperatures at different altitudes.

In this article, author Bill Robertson attempts to help readers understand some of the Earth's heating and cooling mechanisms and how they relate to global warming. Figures are provided to help facilitate learning.

One tried-and-true way to hook students' attention and promote long-lasting understanding is to sequence science instruction in an explore-before-explain instructional sequence. In these lessons for the second through sixth grade band, elementary students investigate the interaction between "cold" and "hot" substances and…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, Dryden Flight Research Center, and their partners at other NASA centers and in private industry are currently developing X-33, a prototype to test technologies for the next generation of space transportation. This single-stage-to-orbit reusable launch…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this interpretation produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, and their partners at other NASA centers and in private industry, are designing and beginning to develop the next generation of spacecraft to transport cargo, equipment, and human explorers to space. These vehicles--the Ares I and Ares V launch…

The Learning in Science Project (Primary)--LISP(P)--investigated the ideas and interests children have about hot and cold. Data were obtained from 25 children (12 boys and 13 girls), ages 8 to 11, using the "interview-about-instances" (IAI) procedure. Areas investigated included: (1) the meanings of the words…

Described is an activity which can be used to investigate heat expansion in a solid. Included are background, materials, procedures, and suggested discussion questions. A diagram of the apparatus is provided. (CW)

This unit consists of four parts. Part 1 contains a five-item instrument designed to help teachers clarify their own views about "burning." Part 2 discusses scientists' views about burning and lists answers to the survey instrument presented in part 1. Part 3 contrasts scientists' views with children's views, using children's comments…

The Science in Action series is designed to teach practical science concepts to special-needs students. It is intended to develop students' problem-solving skills by teaching them to observe, record, analyze, conclude, and predict. This document contains a student workbook which deals with basic principles of physical science. Seven separate units…

Provides an annotated list of references on specific topics covering computers in general science and math. Topics include: artificial intelligence, CAI, LOGO, a heat capacity experiment, microcomputer tutorials, a Monte Carlo simulation, factoring, a geology simulation, polynomials, spreadsheets, a gas model simulation, integers, and…

The world is faced with a variety of environmental problems. No country has escaped pollution and resource depletion. Basic ecological principles are often ignored and sometimes this contributes to ecological disasters. This volume is designed to provide basic information about the quality of the earth's energy resources. The visual aids,…
