• Why is it important to know
your blood type?
• What can you do if you don’t
know your blood type?
Introduction
• Donated blood is used for blood
transfusions.
• Not every type of blood can be safely
donated to every individual.
• This lab will allow you to investigate why
type O blood is especially useful in
blood transfusions.
Scientific Question
• Given what you know, write your
scientific question for this lab.
Hypothesis
• From your understanding of
blood typing, what do you predict from
your investigation of “Do You Know
you’re A-B-Os?”
Materials
•
•
•
•
3 paper cups
3 plastic droppers
White paper
Vinegar

Pen
3 plastic petri dishes
Toothpicks
Acrylic floor cleaner
Procedures
• Make sure you have your surgical gloves on.
The food dye will stain your clothes
permanently!
• Label the paper cups, A, B, O (if time permits,
AB)
• Mix 5 ml water, 15 ml acrylic floor polish, and
3-4 drops of red food dye together. Poor this
mixture into the cup labeled Blood Type A.
Procedures -- cont’d
• Mix 5 ml water, 15 ml vinegar, and 3-4
drops of red food dye together.
• Pour mixture into the cup labeled Blood
Type B.
• Mix 20 ml water and 3-4 drops of red
food dye together.
• Pour mixture into the cup labeled Blood
Type O.
Procedures -- cont’d
Blood Type A
• Using an eye dropper, put 20-25 drops
of Blood Type A into the petri dish
labeled A.
• Add 20-25 drops of Blood Type O into
the petri dish labeled A.
• Stir with the popsicle stick.
• Record observation.
Procedures -- cont’d
Blood Type B
• Using an eye dropper, put 20-25 drops
of Blood Type B into the petri dish
labeled B.
• Add 20-25 drops of Blood Type O into
the petri dish labeled B.
• Stir with the popsicle stick.
• Record observation.
Procedures -- cont’d
Blood Type A
• Using an eye dropper, put 20-25 drops
of Blood Type A into the petri dish
labeled A and B.
• Add 20-25 drops of Blood Type B into
the petri dish labeled A andB.
• Stir with the popsicle stick.
• Record observation.

Some Things to Consider for
Your Lab Report…
• Which blood types can receive a
transfusion of type A blood? Type O
blood?
• If some blood types are not available,
how might O blood be useful?
