TODAY: LESSON 3

• Chicken wings
• explanation for the finger tapping experiment

Labcoat

Rubber gloves

Lab goggles

Hair over shoulderlength must be tied up.

MATERIALS NEEDED:

Tweezers

Rubber gloves

Scalpel

Scissors

STEPS:

• Collect materials and go back to station.
• Put on your rubber gloves.
• Come back to collect your chicken wing, make sure to bring the cutting board.
• Read the worksheet again!

Getting under the skin: Part 1

• Look at the chicken wing and compare it with the figure to the below.
• Find the upper wing, the lower wing and the wingtip.
• Look at the point where the wing used to be attached to the body. You might see cartilage and bone marrow.

Getting under the skin: Part 2

• Lay your chicken wing so the shoulder joint is on the left, the wing tip is on the richt and the elbow joint is pointing down.
• Using the scissors, cut down the middle of the skin, starting at the top end of the upper wing. See cut 1. Try not to cut through the muscles below the skin.

Getting under the skin: Part 3

• Cut down the sides of the skin to make a T-shaped cut. See cut 2 in the picture.
• Fold as much of the skin back as possible so you expose as much of the joint as possible.

Muscles:

• Look at the muscles in the wing. They look like bundles of light pink tissue.
• Find 2 muscles that bend and straighten the elbow joint.
• Hold the wing down at the shoulder and first pull on one muscle and then the other. Look at what happens.

Muscles:

• Tendons are shiny white tissues at the end of the muscles that attach the muscle to the bones. Find as many tendons as you can on the chicken wing.
• Pull on a tendon to see how it helps the chicken move its wing.

Joints and ligaments:

• Bend and straighten the elbow joint. Look at how the bones fit together.
• Ligaments connect bones to other bones at joints. They look like a shiny white covering of the joint surfaces.
• See if you can find the ligaments on the elbow joints.

Assignment:

• Make a biological drawing of your dissected chicken wing. Make sure you label the parts you can see. (skin, muscle, tendons & name the bones you can see)
.
• Don't forget to take pictures for Wolfert Portfolio!

CLEAN UP:

1. Throw away the chicken wing.
2. Bring the material to the front.
3. Hand in your drawings.
4. Remove gloves.
5. Clean desk (and own pencils etc.) down with hygieniv wipes.
