This lab helps students understand how muscles work in pairs to move bones. A chicken wing has bone structure similar to the arm of a human, with a humerus, radius, ulna, and small hand-like bones. Make sure chicken is kept cold until used, to prevent bacteria growth. Students should also wear latex gloves. The white tendons are easy to see. The ligaments are not easy to see and may go unnoticed. You can crack the large humerus bone to show students the bright red bone marrow inside.
