RISK ASSESSMENT

Risk Injury Prevention

Fill out a risk assessment for your experiment

METHOD

1. Place the chicken wing on the tray.

2. Using the scissors and scalpel, gently pull away the skin from the chicken wing. Put the tip of the scalpel blade between the skin and the muscle to separate the skin from the muscle.

METHOD

3. When you have completely removed the skin from one joint, inspect it carefully. Follow each muscle near this joint from one end of the muscle to the other. Try pulling on the muscle.

4. Use scissors to cut through the joint. As you do so, look for tendons and shiny white cartilage.

METHOD

5. Take a photo of your chicken wing or draw a sketch of the chicken wing as you saw it.

6. Place your gloves and your chicken pieces in the plastic bag the teacher has put out for you.

RESULTS

• Write your observations here and display any photos here.

DISCUSSION

1. Sketch one of the joints in the chicken wing. Label the bones, the tendons and the muscles. Show clearly where the muscle inserts (attaches to the bones). Use arrows to show how the bones move when the muscle is shortened.

2. Feel the cartilage with a gloved hand. Does the cartilage feel rough or slippery? Why does it need to be slippery?

3. Is cartilage harder or softer than bone?
