Since their release in 1996, the National Science Education Standards have provided the vision for science education reform. But has that reform actually taken hold in elementary school? "Yes!," reports Robert Yager, editor of Exemplary Science in Grades PreK-4: Standards-Based Success Stories. "Probably the Standards have done more to change…

Presents a simple, economical model of circulatory behavior that illustrates the effect of changes in cardiac output, peripheral resistance and compliance on arterial blood pressure. (CS)

Models of the motion of an object through space are discussed. The material begins with the simplest view possible in which gravity is the only force examined. Discussion progresses to an examination of the drag force, which is the resistive air force of the wind. Suggestions for further improvements are made at the conclusion of the presentation.…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical high temperature gas-cooled reactor (HTGR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating its use with a simplified model. The heart of the module…

This module is part of a series on Physical Processes in Terrestrial and Aquatic Ecosystems. The materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process.…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical pressurized water reactor (PWR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating its use with a simplified model. The heart of the module is the PWR…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical liquid metal fast breeder reactor (LMFBR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating the use with a simplified model. The heart of the module is…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. Primary production in aquatic ecosystems is carried out by phytoplankton, microscopic plants…

Describes software, hardware, and devices that were designed to provide students with an environment to experiment with basic ideas of mechanics, including nonlinear dynamics. Examines the behavior of a Lorenzian water wheel by comparing experimental data with theoretical results obtained from computer-based sensors. (MDH)

Provides a model that maps out five stages of relating library and scientific research: (1) establish an interest; (2) narrow a topic; (3) clarify the variables; (4) refine the procedures; and (5) interpret the unexpected. Provides a student questionnaire for selecting a topic and a format for general note taking. (MDH)

This book presents information, activities, and paper models related to aviation. Most of the models and activities included use a one page, single concept format. All models and activities are designed to reinforce, clarify, or expand on a concept, easily and quickly. A list of National Aeronautics and Space Administration (NASA) Center education…

The nine Reactor Statics Modules are designed to introduce students to the use of numerical methods and digital computers for calculation of neutron flux distributions in space and energy which are needed to calculate criticality, power distribution, and fuel burnup for both slow neutron and fast neutron fission reactors. The last module, RS-9,…

This document consists of a collection of classroom activities as they appeared in the "Aviation and Space Education News" from 1988 to 1991. The 45 activities in the document are organized in the following sections: (1) Aeronautics; (2) Earth Science; (3) Space Science; (4) Life in Space; (5) Rockets; and (6) Models. Each activity is…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. Soil heat flow and the resulting soil temperature distributions have ecological consequences…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. This report introduces two models of the thermal energy budget of a leaf. Typical values for…
