Intended Grade Level - 6-10
Using a world map, students will be able to:
examine the worldwide distribution of the ABO blood types
observe patterns among the locations where these blood types are prevalent
locate geographic locations on a world map
devise a color key to mark the location of the ABO blood types
By performing the lab, students will determine the geographic distribution of the ABO blood types. They will use a world map to color code the locations of the blood types and to determine patterns of distribution.

Activity Management Suggestions
Make transparencies of the 1/4 inch Grid, which is provided at the end of the teacher pages. Students can use this grid to estimate areas on their maps.
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 distribution of blood types and the ABO antigens. Students may also be grouped with other students to provide peer assistance.
Students can research the Rh blood group and create a map showing how the ABO and Rh blood types are grouped world-wide. Students can research additional information about genetic drift and natural selection and how these environmental influences affect the distribution of blood types around the world.
