Sixth Graders Take On Blood Typing and Genetics

Sixth-grade students in science teacher Helen Haskell’s class wrapped up a genetics unit with a lesson in blood typing and organ donation.

Students were given this scenario: A gentleman needs a kidney transplant, and you must test the “blood” of eight relatives to determine their blood type and whether they are a potential donor match.

The “blood” was colored milk, and students used water or vinegar to show different responses to the “chemicals.”
The unit finished with a discussion of which relatives could move on to further testing.

“In seventh grade, students will host a blood drive,” Haskell explained about her rationale for the lesson. “I also wanted them to learn a bit about organ donation.”

The Sundevils learned that there are many criteria for organ donors and recipients to be compatible, and one is that the blood types must match.
