This qualitative case study investigated the implementation of the Next Generation Science Standards (NGSS) by sixth-grade teachers in diverse educational settings within the Central Valley of California. The research focused on identifying the practical successes and ongoing challenges faced by educators in elementary and middle school…

Examines possible energy options and outlines assessments and conclusions influencing recent top level energy thinking and planning. Indicates that no nation on earth appears to have either a coherent long-range energy strategy or the institutions needed to devise one. (JR)

Provides facts which dispel widely held fallacies about the consequences of coal-burning, most of which are physics-related. Concentrates on air pollution as the major contributor to the public hazard from coal-burning. (GA)

Describes four orders of marine mammals: Cetacea (whales and porpoises), Pinnipedia (seals, sea lions, and walruses), Sirenia (sea cows), and Carnivora (sea otter, marine otter, and polar bear). (MA)

During the present decade, there has been increasing interest in and concern for the fate of marine mammals. Aspects of these changing attitudes, including legislative actions, are examined. (MA)

Recent legislation has been enforced to reduce porpoise losses in the nets of tuna fishermen. This article discusses some of the behavioral causes of porpoise mortality and described solutions that may or may not work. (MA)

Presents a method of wildlife management that is based on a critical habitat approach. This is illustrated with the walrus as an example. (MA)

Looks at the potential of wood as a chemical raw material to replace the dwindling supplies of fossil fuels as a source of hydorcarbons and, to a lesser degree, of energy. (GA)

Outlines the problems facing the United States with mineral reserves being depleted, and the consumption of minerals outstripping production. Expresses concern about the deteriorating mineral position, and the ignorance and confusion of the public with respect to mineral production and supply, energy requirements, and environmental consequences.…

Presents a long-term energy policy, to ensure a stable world civilization in the next century, that requires the developed nations to lower their energy consumption to the present world average. (GA)

Summarizes the criticisms of the Office of Science and Technology (OSTP) review committee. Emphasizes research deficiencies in most of the major energy programs. (MA)

Radio tags to track wildlife have been used for years. However, such tagging of whales has been more complicated and less successful. This article explores the latest technology that is designed to give information over a long period of time. (MA)

This manual is a resource guide on energy conservation for teaching environmental education in grades seven to twelve. It contains 25 student activities which are grouped into four goal oriented units. The main objectives of the project are to increase the student's understanding that: (1) Natural laws limit energy availability; (2) Energy…

Describes the use of the net energy concept in the classroom as well as its influence on technology. (LS)
