• • Diamagnetic and Paramagnetic Examples - This video does a lot of great small demos of paramagnetic and diamagnetic substances. It gets a little more technical (in terms of if it is attracted/repelled by the magnetic field, and if it rotates toward or against the magnetic field) than we do but it's still great examples of magnetism that is different than you have experienced before. It also has a brief explanation of the pairing in the orbitals that causes this at the end of it. Additionally the professor presenting it really likes to move his eyebrows around - so enjoy that too. 

  • Einstein Introduction - MinutePhysics video giving a brief introduction to Einstein's Quantum concept and equations. 

  • Wave-Particle Duality Explained Part 1 and Part 2 - MinutePhysics video giving a basic 2-part explanation of Wave-Particle Duality. 

  • Heisenburg's Uncertainty Principle Experiment - This video shows a quick demonstration with a laser and an explanation of the phenomenon seen using Heisenburg's Uncertainty Principle and its corresponding equation. (it's also embedded in one of the notes vodcasts)

• Electron Configuration - This site has "learning objectives" posted at the beginning of each section that allow you to pick a topic you want to read about to understand it more [Ex. electron configuration [aufbau's principle for filling by energy, hund's rule, notations for ions/atoms, electron repulsion, etc), effective nuclear charge (Zeff), dia/paramagnetism, etc]. Great information and informative diagrams - can be very helpful if you need information on a topic again or in a different way than we discuss in the notes. 

Photoelectric Effect:

• • Photoelectric Effect Explained - The first 3-4 minutes of this video do a nice job with a basic explanation of the photoelectric effect. The analogy with the elephant in particular

  • Photoelectric Effect PhET Simulation - This site allows you to simulation the photoelectric effect experiments as a simple cartoon diagram to help understand it. 

may help with understanding why a minimum frequency of light is needed to produce photoelectrons. Problem Solving with Photoelectric Effect - Ignoring the intense background music (no clue why they did that!) the first 4 minutes or so of this video is EXCELLENT for the problem solving in our class. Past about 4 minutes it gets more complicated (it's a Physics video) than we will calculate with in AP Chem. There are some terms we don't tend to use in the beginning as well (like those that are discussed with "threshold"), but the rest should help a lot with understanding the problems in this chapter. 

• • Photoelectric Basics - This video was made by an AP Chemistry teacher as an overview/review of the Photoelectric Effect. A simulation is used to show the photoelectric effect for various metals and explain a big about work function (toward the end of the video). 

  • Photoelectric Effect Demo - A demo from UC Berkeley for their General Chemistry class. It shows the photoelectric effect in terms of the energy of the photoelectron ejected for different wavelengths of light. 

  • Schrödinger's Cat Simple Explanation - often when we cover these topics in APC and we mention Schrödinger someone will ask about the cat problem. This is a thought problem he designed to explain his ideas related to quantum physics, not an actual experiment. But here is a good short explanation on what this thought problem was and how he used it to try to further the understandings and concepts of quantum physics.
