By the end of this section, you will be able to explain the law of the conservation of energy; describe some of the many forms of energy; and define efficiency of an energy conversion process as the fraction left as useful energy or...

An explanation of types of energy, how living things use energy and how they can convert energy forms. This is a good, basic, start to studying this characteristic of life.

Definitions of various forms of energy are presented along with a brief scientific history of energy related concepts.

This is a resource on solar energy, photovoltaic energy, solar thermal heat, solar thermal power plants and other forms of energy.

This lesson focuses on the scarce and non-renewable nature of fossil fuels in order to stimulate student thinking about energy conservation. It emphasizes the fact that saving energy can be good for the wallet as well as the earth's...

Learn about the definition of energy, the forms that it comes in, and the difference between renewable and nonrenewable sources.

A collective which looks at mass and energy. Identify the forms of measurement and how to convert them as well as scientific notation. Practice application with homework problems.

Explains what energy is, the forms it takes and how it is stored, and what humans use it for. Has links in the text to more information about key vocabulary words and to short biographies of significant people who have contributed to our...

The report provides an overview of the electricity consumption in households in 2001. End-use (lighting, appliances, heating) data is presented in written, graph and table form. Background on efficiency standards and regional factors...

Information about the radioactive element, Uranium, atomic number 92. Describes its history, physical and atomic properties, how abundant it is on the Earth, and permissible exposure limits. Also discusses sources, uses, isotopes,...

This module is the introduction to model rotational motion. All of the concepts are conveniently recast into forms that have the same mathematical forms as their translational counterparts.

LEED is a program for green building certification. Buildings are rated on a points system in one of five categories, including building design and construction, interior design and construction, building operations and maintenance,...

Biomass is organic material which has stored sunlight in the form of chemical energy. Biomass fuels include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes.

The sun's energy is the primary source of energy for all surface phenomena and life on Earth. Combined with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this...

Explains, in scientific terms, what hydroelectric energy is and how it is produced. Discusses the lifespan of a hydroelectric facility, the risks and adverse effects of producing hydroelectricity, and how this form compares with other...

Provides a definition and explanation of fission, the splitting of a heavy nucleus into two roughly equal parts, and fusion, the process where two nuclei combine together to form a larger nucleus.

The Carnot cycle is described, illustrated and explained. The Carnot efficiency equation is given and interactive JavaScript form allows the visitor to investigate the effect of the reservoir temperature and the sink temperature upon the...

Learn about the use of coal as a usable form of electricity, and find out the history of this natural resource.

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

In the modern world, virtually everyone is familiar with electricity as an accessible, essential form of energy. In electricity's earlier days, scientists used the buildup and release of static electricity.

Most of us have seen the rainbow-hued breakdown of the composition of light. Light is of course a form of energy. A magnetic field changes the behavior of light- a phenomenon known as the Zeeman effect.

This site explores the importance of clouds and how clouds are formed. Content details common atmospheric cooling mechanisms and atmospheric stability.

[Free Registration/Login may be required to access all resource tools.] Students investigate specific properties that can be predicted by an element's position on the periodic table. Additionally, they will look at the formation of ions,...
