Chicken Wing Dissection

1) The document describes an experiment using chicken bones to learn about human bones, as chicken bones have a similar structure and are easier to study. 2) The experiment involves removing meat from chicken wings, observing the bones and marrow, and soaking bone segments in vinegar or water to see how vinegar removes calcium from bones. 3) Students are asked to record their observations after 3 days and submit any data collected on the effects of vinegar versus water on the chicken bones.

Chicken Wing Dissection

To better understand what bones are made of, we want you to experiment on a chicken bone. If we are
studying the human body, why are we going to do an experiment with a chicken bone? Well, chicken
bones are similar to our own. They are not exactly like human bones, but they are similar enough that
we can learn a few things about our own bones by studying those of a chicken. Also, chicken bones are a
lot easier to find and experiment on!

Materials:

1. A cooked chicken wing


2. A pair of rubber or plastic gloves
3. White vinegar
4. Two plastic containers with lids (just big enough for a chicken wing and some liquid)
5. Plastic wrap
6. A parent with a knife

Procedure
1. Put on the gloves
2. Using your fingers, remove all the meat from the bone. If you can’t get it all off with your
fingers, ask your parent to use the knife to help you. As you are doing this, see if you can see
anything else besides meat. The meat is muscle, but the bones are connected with ligaments,
and there is cartilage at the end of the bone. Can you see any cartilage or ligaments? Don’t
worry if you can’t. That’s not the main point of the experiment.
3. Look at the bones. Notice that there is one thick, long bone that connects to two thinner long
bones. Does that sound familiar? It should – that’s what the bones in your arm are like!
4. Cut or break the largest bone (remember, it’s called the humerus) in half and look on the inside
of the bone. Do you see something red there? What is that red stuff? It is the chicken’s red bone
marrow. That’s where the chicken’s blood cells come from.
5. Do you remember what material makes the bone strong? It’s calcium. We are going to do an
experiment that actually removes calcium from the bone to see what happens to it. Fill one of
the containers about half full of vinegar.
6. Fill the other container about half full of water.
7. Pull the two thinner bones of the wing away from each other.
8. Put one of the two bones in the container that has water.
9. Put the other bone in the container that has vinegar.
10. Put plastic wrap over each container.
11. Put the containers aside for a few days.
12. Vinegar is an acid that will remove the calcium salts from the bone. Make a hypothesis about
any differences you think you will find between the two bones.
13. After three days, check your chicken bones. What happened? Record your results.

Submission:

Record your results and build a table and graph the results from the vinegar and water. Submit the data
and your conclusion.
