Intended Grade Level - 6-10




Working in collaborative groups, students will be able to:

  • Examine the ABO blood groups and antigens present on the surface of red blood cells

  • Identify the antigens that make each blood type unique

  • Construct a model of antigens involved in ABO blood group

  • Present their models to the class

  • Follow written directions and complete a given task

Activity Description


Students will create a “Hey, What's Your Type” Wheel to explore the ABO blood groups. Using the wheel and an antigen template page students will construct the antigens responsible for the ABO blood group.

Activity Management Suggestions


For students needing more assistance: Group these students with peers who can assist them during the activity. Check often for understanding.


For highly able students: Allow these students to do research on the carbohydrate structures that make up the ABO and Rh antigens. Students may also be grouped with other students to provide peer assistance.




Students can research Rh antigens and create a lesson or template showing how these factors provide different markers for the red blood cells.
