BACKGROUND INFORMATION AND MATERIALS LIST:

Students will begin the lab by reading the essential question and background information. This can be done individually, as lab groups, or as a whole class. If you consider lab groups, you also might include some type of whole class formative checks before digging into the lab.

Materials List:

• 1 whole chicken wing
• dissection kit
• dissection tray
• gloves

PROCEDURE:

In this lab, students will be conducting a dissection using a raw chicken wing. Following the steps included in the lab, students will be able to thoroughly see how the muscular system and skeletal system work together to provide movement. Once students have cleaned up, they will then begin to identify and compare the organs of the human arm to that of the wing of a chicken.

CHECK FOR UNDERSTANDING:

At this point in the lab, students will be checked for understanding by answering questions about their findings. Here are a few that come with the lab:

• What color are the muscles? The tendons?
• Where do the muscles attach?
• Locate and describe the different muscle segments or groups.
• What do you think the function is of these different segments?

CONCLUSION

Students will go back to the essential question and write a CER (Claim, Evidence, Reasoning) to conclude the lab. Once completed, students will reflect back on their learning by answering the following questions:

1. Identify the antagonistic muscles observed in this lab and how they function together.
2. Compare and contrast the muscles of the chicken wing to the muscles of the human arm.
3. The muscular system works in conjunction with the skeletal system. Explain how the muscular system and skeletal system work together to move the body.
