Does a material encourage or discourage the flow of thermal energy? Pupils learn that the answer determines whether a material is a conductor or insulator in a concise video presentation. The lesson also includes several examples of...

Finally mysteries are revealed! A thorough lesson shows how the scientific method helps to solve mysteries of now common elements. Young scientists watch the video presentation to gain a thorough understanding of how Madam Curie...

Alas! A team of 11 researchers has been beamed to separate dimensions. The viewers' challenge, if they choose to accept it, is to figure out how to use an experimental teleportation robot to get them home safely.

Have young engineers always wondered how a light bulb works? Now's their chance. Viewers of an illuminating YouTube video learn about electric current, conductivity, and resistance. They see how engineers use low-conductivity conductors...

Time to expand your thinking! A video lesson begins with an explanation of topology and its application to new technology. The narrator shares examples of electron transfer of electricity and data storage in computers.

Help your classes visualize the invisible. The 26th episode in a Crash Course physics playlist highlights the fields created by charged particles. Using examples and diagrams, the presentation demonstrates the magnitude and direction of...

A video introduces metallic bonds. It discusses what makes a bond metallic and the related properties. Next, the narrator covers conduction, malleability, ductility, and more.

To conduct or not to conduct ... that is the question! The sixth and final video in a series depicting elements, mixtures, and compounds digs deeper into the concept of conductivity. Pupils learn how the arrangement of electrons within a...

Scholars learn about ionic substances, but how often do they encounter them in their daily lives? The final video in a six-part series explains ionic substances are more common that most people realize. The narrator discusses the...

Tiny discoveries won big at the 2016 Nobel prize ceremony, recognizing chemists who developed new machines out of molecules and pushed the limits of nanotechnology. Individuals see how physicists created new materials through topology...

Want a quick explanation for how resistance works as an electric current flows through a wire? Then check out this video that covers electrons, conductors, ions, and the formula for resistance. It also graphs how voltage varies...

Semiconductors are in everything from your cell phone to rockets. But what exactly are they, and what makes them so special? Find out from Jamie, a Ph.D. student in Electrical Engineering and Computer Science at MIT. [4:45]

Paul Andersen explains how the resistivity of a material opposes the flow of charge. [4:22]

This video narrated by Paul Andersen explains how the charge distribution can be affected my electric forces produced by a charged object. In an insulator charges are fixed but in conductors the charges can move. Induction occurs when...

In this video, Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object, the net total of charge will not change. [6:07]
