Determine which of four possible donors could safely give blood to a patient, then develop a case history of a mother and her children to determine the safety of her pregnancy, all using WARD’S Simulated Blood. In the process, students learn to identify antigen/antibody reactions, and how those reactions affect the body’s immune response, as well as the basics of ABO and Rh blood typing. The kit contains enough materials for 12 setups, a teacher’s guide, and student copymaster.
