Blood Types in Korea Infographic , Purpose Games

Recently, I posted a brief history of blood transfusions and how the world's improved knowledge of the blood transfusion process coincided nicely with the First World War. I have lived in Korea for the past four years, and one of the "quirky" things you'll find out when you live in Korea, is that some people have a superstitious belief that blood type is related to personality. The infographic below summarizes this, nicely. I, in fact, never even knew my blood type until I came to Korea. I'm A+ by the way, so you can MAYBE learn about my personality by reading the infographic below ... IF you believe in that sort of thing.

As a teacher, I like to add Gamification into my lessons as much as possible. One website I really like using is http://www.purposegames.com/ They have a plethora of games to choose from, and students can race against the clock to test themselves on many topics. Purpose Games is a wonderful tool for teachers of any subject. I have created a game , in the past, to test my skills in the Korean language and vocabulary. Below are some examples of games testing students on their knowledge of blood types. The games are listed in order of difficulty. Follow the links to check them out, and see how well YOU will do !

WWI & Blood Transfusion History, Blood Typing Game !

In the 1660's, in France and Britain, there were 3 successful transfusions of blood from a sheep into a human. The patients most likely survived, miraculously, due to the small amount of blood transfused. However, at this time, there were also several UNsuccessful blood transfusion attempts from an animal into a human. In 1668, both France and Britain banned these types of procedures and in 1670, the Vatican condemned the experiments, as well.

In the early to mid 1800's(1818-1840),British physician, James Blundell had some mixed success with human to human blood transfusions. However, these types of operations were still seen as too risky, and not much was done until the early 1900's.

It wasn't until 1901 that three human blood groups, (O, A, & B ) were discovered by Austrian, Karl Landsteiner. Blood transfusions could now be performed on a scientific basis. He discovered that when incompatible blood types are mixed, the body's immune system causes the red blood cells to clump, and the patient would die. For his work on blood transfusions, Landsteiner would eventually be awarded the Nobel Prize in Physiology and Medicine in 1930.

In general, people with blood type O Rh D are called "Universal Donors" because they can donate blood to people with blood types A, B, AB, or O.

People with blood type AB Rh D are called " Universal Recipients" because they can receive blood from any other blood type, A, B, AB or O. However, people with AB blood can ONLY only donate blood to other people with AB blood.

So how is it that the rarest blood type is also the one that is a universal recipient? The answer lies in the antigens that are present in most blood types. O blood types have no antigens, A blood types have a specific antigen, as do B blood types. AB blood type means that the antigens for A and B blood are both present. Since both A and B antigens are present in a person with AB blood, the recipient won't reject the blood. O blood has no antigens, and is referred to as universal donor blood, so that will not cause a reaction.

The timing on all of these scientific discoveries of blood type and blood type compatibility could not have been better. The world was about to embark on the bloodiest event known to man, The Great War, aka World War I

World War I would introduce some terrible weapons to mankind; the tank, warplanes, submarines, the machine gun, grenades, and chemical weapons. It would also be fought in a particularly brutal manner - trench warfare.

Trench warfare had been used in the US Civil War, but not on this scale. Trenches were dug in Zig-Zag formations to prevent enemies from entering and having a clean lane to shoot down with machine guns. An estimated 10% of the soldiers who fought in the trenches died either in charges over the top or by disease. Heavy rainfall would also flood the trenches, so drowning was a constant threat. The soggy conditions often resulted in “trench foot,” which could lead to gangrene, if untreated. The threat of disease was also, ever-present, as rats, flies and lice bred in huge numbers.

Life within the trenches was a miserable existence and the nature of trench warfare prompted some deadly innovations — the first use of poison gas and the widespread use of the barbed-wire fence. The fencing created a contested territory, or “No Man’s Land,” between the two enemy trench systems in which neither side could move openly.

The use of blood transfusions during world War I was made possible by a trio of well-timed discoveries earlier in the century. 1. Not all blood is the same i.e. (A, B, AB, O ) 2. Sodium Citrate could be used to stop blood from clotting and 3. Blood could be refrigerated. These breakthroughs made transfusions safer and allowed blood to be stored and carried to the battle front.

How DO Solar Panels work ?

IF you are like me, then maybe you have wondered, "How exactly DO Solar Panels works, anyways ???" Both the TED-Ed video and the infographic below should "shed some light" on the process. ;) Enjoy !! Here is a link to a Ted-Ed lesson on the video. https://ed.ted.com/lessons/how-do-solar-panels-work-richard-komp#discussion">
