Students analyze their social networks using graph theory. They gather data on their own social relationships, either from Facebook interactions or the interactions they have throughout the course of a day, recording it in Microsoft...

This article provides information regarding Nikola Tesla, inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current electricity supply...

Inventor Nikola Tesla is the subject of this extensive PBS site. In addition to information on Tesla's life and work, the site offers insight into the ways in which society and invention affect each other.

Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the...

Keeping the power moving to houses and businesses is the job of the power plant operator. Whether the power comes from hyrdroelectric, nuclear, or coal energy, the power plant operator needs to know how to keep the turbines moving. This...

Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within...

Charge up the Van de Graaff generator and drag the discharge wand close enough to form a spark. What happens to the electric potential energy when you charge the Van de Graaff and when the spark occurs?

Given schematic diagrams, illustrations or descriptions, students will identify the relationship of electric and magnetic fields in applications such as generators, motors, and transformers.

CNN reports in 1999 on China's biggest construction project since the Great Wall, the ecologically controversial building of the Three Gorges Dam on the Yangzi River.

The legendary Lord Kelvin made electricity from water with this ingenious electrostatic generator. (Java tutorial)

Simulate the movement of a rail gun in this interactive model. Learn how a magnetic field is generated by running electrical current through long rods that accelerates a current-carrying cross-rod.

Learners learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity....

Activity 3 investigates Why is lightning so much bigger that a spark from the Van de Graff generator? In Activity 3 of this module, students investigate factors that affect the amount of potential energy that is stored.

Zenobe Theophile Gramme (1826 - 1901) invented the first industrial generator, or dynamo. A deceptively simple-looking machine, it consisted of 30 coils wrapped around a spinning ring of iron.

The greatest increase in demand for energy is envisaged to come from developing countries where, with rapid urbanization, large-scale electricity generation will be required. With environmental requirements for zero or low CO2 emission...

What is solar energy? Learn about solar heating, solar electricity generation, and the advantages and disadvantages of solar power.
