Episode 16 : Passing Gases: Effusion, Diffusion and the Velocity of a Gas
June. 03,2013
We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first appears. In this episode, Hank describes what it means when we talk about the velocity of a gas - to understand gas velocity, we have to know what factors effect it, and how. Hank also teaches you about effusion, diffusion and concentration gradients, before showing off a cool experiment that physically demonstrates the things you have just learned. Sound exciting enough for you? Let's get started.

Episode 10 : Redox Reactions
April. 22,2013
All the magic that we know is in the transfer of electrons. Reduction (the loss of electrons) and oxidation (gaining electrons) combine to form Redox Chemistry, which contains the majority of chemical reactions. As electrons jump from atom to atom, they carry energy with them, and that transfer of energy is what makes all life on earth possible.

Episode 9 : Precipitation Reactions

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.

Today's Crash Course Chemistry takes a historical perspective on the creation of the science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of how we went from alchemists to chemists, who understood the law of conservation of mass as proposed by a decapitated aristocrat, and explains how we came to have a greater understanding of how chemical compounds work and eventually a complete understanding of what atoms and molecules are.

Episode 2 : Unit Conversion & Significant Figures
February. 18,2013
A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units. Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists.

Destinos: An Introduction to Spanish
Destinos: An Introduction to Spanish, also known simply as Destinos, is an educational television program created by Bill VanPatten, who was, at the time, Professor of Spanish and Second Language Acquisition at the University of Illinois at Urbana Champaign. The show, designed to introduce viewers to the basics of Spanish, had two seasons, beginning in 1992. Its 52 episodes are often used for educational purposes in schools and are still broadcast regularly on many PBS stations, as well as many local channels.
Destinos was produced by WGBH Boston and funded by the Annenberg/CPB Project, with additional funding by the Geraldine R. Dodge Foundation.
Britain's Poshest Nannies
This documentary follows the second-year students of Set 36 at Norland College, a quintessentially British 120-year-old childcare training college in Bath which turns its students into elite 21st century Mary Poppins-style nannies. The programme gives an insight into how contemporary Norland students follow the college's traditions, though the students are also taught more modern disciplines, such as advanced driving skills, how to escape the paparazzi, taking corners at speed in the rain, lifesaving and self-defence. If they successfully finish the 14,000 pounds per year course, a lifetime of employment and travel prospects could be theirs for the taking. Norland Nannies have been sought after by the rich and famous for over a century. Most recently the Duke and Duchess of Cambridge hired a Norlander as nanny to Prince George. Founded in 1892 by Emily Ward, the college is renowned for its rigorous rules, traditional uniform, perfect hair and clean white gloves.
