I could not embed the video, but this is the link to the video. It shows that the electric field inside a conductor is zero.

This video shows demonstrations of charging by contact, induction, and polarization. It also helps visualize the idea that a charge will move along the electric field.

This video shows a demonstration of charging by friction. It shows that different materials will acquire different charges when rubbed together because of differences in chemical make-up.

This article provides information on recent superconductivity research. Although we did not discuss superconductivity in class, it still seems a relevant and interesting article.

http://www.technologyreview.com/view/522301/physicists-discover-worlds-first-naturally-occurring-topological-insulator/
This article discusses topological insulators, materials that are conductors on the surface but insulators on the inside; these materials are a new and exciting discovery in physics/chemistry.

This website has good notes and diagrams on the electric field.

http://www.physicsclassroom.com/class/estatics/Lesson-3/Coulomb-s-Law
This website has good notes and practice problems on Coulombs Law

http://hypertextbook.com/facts/BarryLajnwand.shtml
This website talks about the electric fields (Oooooh) created by electric eels (Oooooh) and the voltage of the different discharges.
