Students learn the fundamental concepts of electrical energy. Easy-to-understand animations illustrate the concepts of electric charge and electric current. Static electricity and the role it plays in creating lightning is also described. Important terminology includes protons, electrons, repel, attract, charges, charged objects, electrical discharge, electric field, and electric force.

Students explore the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is given to safety and electricity. Concepts and terminology include charge, current, lightning, battery, generator, and wiring.
Electricity makes life easier every day. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. Students will discover the properties of electricity and what is needed to keep the lights on. Part of the Real World Science series.
Part of the "A 3-D Demonstration" series. Explores how electric energy became an essential tool with the advent of electricity storage, allowing the flow of current to do useful work. Defines and examines conductors, insulators, voltage, and current, using a water flow model to help ensure understanding. Explains the difference between electron flow and current flow models. Also develops the nature of direct and alternating current (both one- and two-phase). Specific modules include Tapping a Source, Conductors and Insulators, Direction of Flow, Potential Difference, Measuring Voltage, Measuring Current, Alternating Current, and AC Voltage. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Presents three key concepts of science: static electricity, magnetism, and generating electricity. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Grab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge.

What is electricity and how is it made? What kinds are there? What are circuits and switches? Is electricity dangerous? Answers these questions with easy-to-duplicate experiments.
Investigates some of the key concepts of physics. Using a drum kit, we look at how sound works, how we make it, and how it gets around. Also, examines electricity and electromagnetism and notes the similarities between a remote control car and a mobile phone charger. Finally, takes a look at radioactivity and identifies a radioactive device that can be found in almost every family home.
Adabot learns about electricity after tripping a circuit breaker. Ladayada explains that electricity is measured in amperes. They also use a multimeter to measure the number of electrons in a circuit. Part of the "Circuit Playground" series.
Part of the animated "Johan, the Young Scientist" series. While waiting for his rechargeable batteries to charge up, Johan discovers in ScienScape that electricity is generated by cranking up a dynamo. Professor Hoo then sends him, Ani, and Moki to find how different power stations use different methods of generating electricity.
Part of the "A 3-D Demonstration" series. Explores basic electricity as it was perceived by Benjamin Franklin and other early theorists as well as the principles of positive and negative charge, conduction and induction, atoms and electrons, and elementary charge. Relates Coulomb's Law in detail, including the torsion balance experiment, that led to a breakthrough in scientific theory related to electricity.
In Bruce Logan's lab at Penn State University, researchers are working on developing microbial fuel cells (MFC) that can generate electricity while accomplishing wastewater treatment. In a project supported by NSF, they are researching methods to increase power generation from MFCs while at the same time recovering more of the energy as electricity. Through their research projects, Logan’s team has already proven that they can produce electricity from ordinary domestic wastewater.
Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
Learn the story behind the steam engine, electricity, and other important inventions. From the Kool Books series narrated by Hector Bonilla.
Part of the "A 3-D Demonstration" series. Looks at physics principles behind AC and DC generators. Examines the relationship between a changing magnetic field and the induction of electric current. A hand rule is introduced to predict the generator effect in a linear length of conductor exposed to a changing magnetic field. The behavior of a rotating coil in a magnetic field leads to the practical construction of an AC motor. Introduces split-ring commutator generators, as well as the more common alternator as a means of generating DC electricity. Specific modules include Generating Electricity, Inductors, Generator Left-Hand Rule, Generator Electromotive Rule, AC Generators, and DC Generators. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Ladyada and Adabot explain the electrochemical reactions that take place in batteries. After discussing how batteries work, they build a battery out of lemons. Part of the "Circuit Playground" series.
A lit up lamp is the end of an electrical circuit. How is energy produced? How is it distributed? A team traces the path of electricity from the power plant to its place of consumption. Part of Invisible Science and Technology Surrounding Series.
Graphene could make it possible for electricity to move effortlessly through computer chips, thereby allowing computer systems to run faster than ever before. Savings in both heat and energy costs could have graphene replacing silicon as the basis of computer chip construction. Part of the Fast Draw Series.
Students explore the various properties of magnets and the characteristics of magnetic force. Graphics and real-life footage explain how magnets are used in generating electricity. Electromagnets and their many uses are demonstrated as well. Other terminology includes: magnetic poles, magnetic field, electric motor, generator, solenoid, and electromagnetism.
Introduces caveman Zog to energy of movement and stored energy. Working with inclined planes, springs and a bouncing ball, he learns about both kinds of energy and how each kind of energy can be changed into the other. Also, he learns how chemical potential energy is used to create heat, mechanical power, light and electricity.
