Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will...

Several visualizations that help students understand the basic properties of semiconductors. Students can turn a silicon crystal into an insulator or a conductor, investigate the probability waves of an electron, and make a depletion...

[Free Registration/Login may be required to access all resource tools.] Students explore how heat of fusion and heat of vaporization energy are used to create a phase change, and how a phase change can be used to do work.

This free site (requires registration) offers videos that encourage "mind breaks" during the school day. Short videos get kids up and moving for a couple of minutes to help them use excess energy productively and then settle down to...

Learn what power means and how we use it to describe the rate of energy transfer.

[Free Registration/Login may be required to access all resource tools.] This lesson looks at what voltage is and how to solve problems involving voltage. Includes a simulation for exploring how charges work in an electric field.

Information about the element, Thorium, atomic number 90. Covers physical properties, atomic properties, how abundant it is on the Earth, where it is found, and details about health-related regulations. Discusses thorium's potential use...

This site from the Tal Cohen's Bookshelf provides a detailed review of the book, The Emperor's New Mind. An interesting look at the machines of our world and how they may take on more human tasks.

[Free Registration/Login may be required to access all resource tools.] Energy is the ability to do work. In organisms, this can be physical work, like walking or jumping, or it can be the work used to carry out the chemical processes in...

Thermodynamics is a very important branch of both physics and chemistry. It deals with the study of energy, the conversion of energy between different forms and the ability of energy to do work. Through this article, you will begin to...

This site examines the black hole as an object in astrophysics. Delve into this comprehensive resource that covers this concept from its history, to qualitative physics, the reality of black holes, mathematical physics and more.

Rodney Lee Cool spent much of life's work on hyperons. This is the classic biography of a real-life scientist, a particle physicist. It's touching and enlightening, complete and full of science and significance. Requires Adobe Reader. [PDF]
