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.

In today’s lesson, students learned all about blood, 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!

 

¿Eres de mi tipo?

A pesar que la sangre ha sido estudiada por miles de años, el descubrimiento de que existen distintos grupos sanguíneos no fue realizado hasta el año 1901, cuando el Dr. Karl Landsteiner identificó estos tres grupos sanguíneos: ABO. Landsteiner fue distinguido con el premio Nobel por descubrir que cada grupo sanguíneos se compone de dos antígenos diferentes, A y B. Estos antígenos son moléculas localizadas en la superficie de los glóbulos rojos.

En la clase del día de hoy, los estudiantes aprendieron acerca de la sangre, tuvieron la oportunidad de observarla bajo el microscopio y participaron en una actividad de laboratorio donde investigaron sobre los grupos sanguíneos. Los estudiantes usaron un sucedáneo de sangre para determinar quiénes de sus amigos podrían donar sangre de manera segura al Señor Potter, quien necesita de manera urgente una transfusión después de un accidente. Pregúntele a su hija o hijo cómo es que determinaron quién era el donante apropiado.

Lauren loves learning about how the world works (including everything from biology to chemistry to engineering), and is passionate about sharing that knowledge and enthusiasm with others. In the past, she has interned at the Museum of Science, where she educated learners of all ages through hands-on activities, games, and experiments. Other science education organizations with which Lauren has worked include The People’s Science, EurekaFest, and Eureka! of Girls Inc. of Worcester.
