RE-Review!:

Problem Question: What is the effect Hypothesis (IF/THEN/BECAUSE):

of blood GENOTYPE on compatibility

of donation?

RESEARCH:

Materials: Beakers/flasks, goggles (glass safety), pipettes, colored water

To represent blood types

Procedures: (See separate “Blood Lab” sheet) – use colored water to

represent different blood types/compatibility

Solution: Data Collection (tables/graphs) Verification:

Data Analysis

• Universal donor:

• Universal recipient:

Conclusion (use next page and guidelines for a good conclusion in your notebook): include BLOOD, CELLS, DOMINANT, RECESSIVE, GENES, GENOTYPE, PHENOTYPE to explain COMPATIBILITY in donation.

Student Instructions:

- Follow all instructions given to you by your teacher

- SAFETY is your 1ST PRIORITY!!!! (we use goggles any time we use glass!)

- Take care not to CONTAMINATE samples, pipettes, etc.

Procedures: In this activity, you will be simulating what happens when the same and different blood types are mixed. Since blood can carry diseases, you will use colored water to mimic the way blood interacts.

• Look at the chart below.

• COPY IT INTO YOUR “Data Collection” section of your lab outline.

• Across the TOP are the blood types of a person RECEIVING blood.

• Down the SIDE will be the DONOR’S blood type. For each part of the chart, you will check to see if those two blood types “clump” or not. Since we cannot use real blood, “clumping” would happen if you see a color change (e.g. red turns purple)

How To Test:

• Each square of the chart is an individual test.

• Put 3 drops of the receiver’s blood type that is at the top of the column in your test plate.

• Add 1 drop of the donor blood type to the test. Stir with a clean toothpick.

• Did the color of the recipients blood change?

o The blood donation is good if the original color does not change. Put a ( for a good donation in the box.

o If the mixture is not the original color, a bad reaction (“clumping) has occurred. Put a ( in the box.
