Are you my Type?
Even though blood has been studied for thousands of years, the discovery of different blood types was not made until 1901 when Dr. Karl Landsteiner identified the ABO blood groups. Landsteiner was awarded a Nobel Prize for discovering that each blood type is based on two different antigens, A and B, which are molecules located on the surface of red blood cells. Did you know that blood type O, which has neither antigen present on red blood cells is the most common blood type?
In today’s lesson, students learned all about blood composition, had an opportunity to view blood cells under the microscope, and participated in a hands-on laboratory activity investigating blood typing. Students used simulated blood to determine which friends could safely donate their blood to “Mrs. Potter” for a much-needed blood transfusion after a serious biking accident. Ask your student how they determined the appropriate blood donor!
