We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires...

This lesson focuses on energy and power. Energy is a key principle in physics, as it allows work to be done. The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called...

This site from the Colorado State University discusses the Otto cycle of a car engine. Includes a highly mathematical treatment of the efficiency of such engines. Includes a link to a java applet investigating the efficiency of such...

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as...

Students are introduced to various types of energy with a focus on thermal energy and types of heat transfer as they are challenged to design a better travel thermos that is cost efficient, aesthetically pleasing and meets the design...

Refrigerators and heat pumps are described. Their operation is explained and the variables which improve their efficiency is discussed.

The heat engine cycle is defined and discussed. So pressure-volume diagrams are introduced and their use in depicting the cycles of a heat engine is demonstrated. Informative graphics are accompanied by reason-filled explanations.

Using a voltage sensor, students will measure how much "electricity" is produced by the wind turbine that they design and build. Students will experiment with blade designs to see which one collects energy from the wind the most...

What kind of unit conversion would you like to do? This site will allow you to do a multitude of conversions. Just click on the specific measurement you are needing to convert. It also provides a history of measurements and a chart of...
