This section of a chemistry textbook reviews the different forms of energy: kinetic, potential, and chemical.

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...

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

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...

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.

Student teams design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy. This thermal energy is next transferred to water (to be...

The concept of potential energy is explained along with the two forms of potential energy: elastic and gravitational. Discusses what gravitational potential energy is, explains the direct relationship between it and mass and height, and...

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,...

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,...

Comprehensive overview of the use of biomass as a renewable energy source. Learn what it is, its forms, its uses, and its impact on the environment.

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...

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.

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.

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

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...

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.

This site provides an excellent overview of the solution process. Content includes a focus on how a solution is formed, energy changes and solution formation, spontaneity and disorder, and solution formation and chemical reactions.

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 article highlights facts about clouds and their role in the Earth's climate change.
