Studying Blood Types
Today we continued our probability experiments and games and we finished our body systems stations packet, which is due tomorrow. In addition, we talked about blood types and transfusions, and we did an experiment to further explore the four blood types and determine which blood types are from those individuals labeled universal donors (type O) and universal recipients (AB). Please ask your child to explain how we used food colouring to represent the four main blood types, combined them by pretending they were from a donor and a recipient of a transfusion, and then recorded the results to see whether the transfusion would be a success or failure. We discussed how the proteins in our blood that are related to our blood type will act upon foreign blood types and cause agglutination, or clumping of red blood cells. If you or anyone in your family has undergone a transfusion and knows something about blood types, please share this with your child now that they have more information to understand blood transfusions!
***Also, if anyone is a doctor or knows of doctors who would be willing to come in and speak with us about general advice he or she would give to maintain good health for children and adults, please let me know. I am trying to put together classroom visitors we can interview, and I appreciate your help or expertise!
