Microbial processes in the deep biosphere affect marine sediments, such as the formation of gas hydrate deposits. Gas hydrate deposits offer a large source of natural gas with the potential to augment energy reserves and affect climate and seafloor stability. Despite the significant interdependence between life and geology in the ocean, coverage…

In this paper a simplified two-parameter model of the greenhouse effect on the Earth is developed, starting from the well known two-layer model. It allows both the analysis of the temperatures of the inner planets, by focusing on the role of the greenhouse effect, and a comparison between the temperatures the planets should have in the absence of…

It is claimed by the company NitroFill and the GetNitrogen Institute that filling car tires with nitrogen improves gas mileage considerably. The reason given is that oxygen leaks out of tires so that the increased rolling friction causes a reduced gas mileage. Because it is hard to do an actual road test, we report on a simple visual test of…

A survey of adults that shows considerable misunderstanding of two major ideas--that there is no energy in fuels and burning involves two stages--is discussed. Proposed are fundamental changes in the way ideas about burning are introduced to children. (KR)

Four energy conservation concept areas are developed in this unit: (1) energy resources are many and varied and have evolved over a long period of history; (2) as much as 30 to 50 percent of the energy in the United States is wasted; (3) homes, offices, and schools account for 24 percent of total energy consumption and savings can be made through…

When the fossil fuels unit was first designed for Science 101 (the currently approved provincial guide for grade 10 science in Manitoba), Canadian support materials were very limited. Since students are asked to interpret data concerning energy consumption and sources for certain fossil fuels, the need for appropriate Canadian data became obvious.…

Describes various aspects of peat, including its origin, chemical composition, industrial chemistry, agricultural uses, and current technologies. (CS)

The purpose of this handbook is to present information about energy and to translate this information into learning activities for children. Chapter 1, "Energy: A Delicate Dilemma," presents activities intended to provide an introduction to energy and energy usage. Chapter 2, "What are the Sources of Energy?" provides…

Reviews some of the important properties of coal and the systems of nomenclature that would be useful to chemists and classroom teachers. (CS)

Outlines a science-industrial arts survey course which presents basic concepts of chemistry as applied to practical experiences. Course topics include: paints; solvents; finishes; metallurgy of iron; precious metals; calorimetry; fossil fuels; batteries; adhesives; cement; and others. The short units were designed for students with limited…

Described is a graduate level engineering course offered at the University of Southern California on coal liquefaction processes. Lecture topics and course requirements are discussed. A 64-item bibliography of papers used in place of a textbook is included. (BT)

Deals with how secondary schools in the United Kingdom ought to be concerned not only with teaching the science of nuclear processes but also with: (1) the technologies associated with power generation from the processes, and (2) the possible social effects of such technologies. (SK)

This book is an energy, electricity, and science resource guide for teachers of grades K-3. The types of energy covered are: coal, oil, natural gas, nuclear energy, renewable energy sources, electricity and food. Thirty-one interdisciplinary energy lessons are the heart of the book. Each lesson is teacher tested and can be incorporated into the…

Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Discusses the incorporation of environmental chemistry topics into the traditional high school chemistry curriculum. Describes and provides lesson plans for the sulfur cycle and acid rain, and radioactivity and nuclear energy. Considers possible laboratory experiments. (CW)
