Flex Your Biceps - Student Lab Inquiry Sheet

Objective: Observe how the various organ systems present in a chicken wing work together to

move the joint. Comparative this understanding to the homologous structures found in frogs,

humans, and other vertebrate animals.

Standards:

S7L2. Students will describe the structure and function of cells, tissues, organs, and organ

systems. e. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration,

reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease).

S7L5. Students will examine the evolution of living organisms through inherited characteristics that

promote survival of organisms and the survival of successive generations of their offspring.

Part 1:

Obtain a heavy (3-5 lbs) object from your teacher such as a dumbbell. Using proper “bicep

curl” form (your teacher may need to demonstrate), raise and lower the object from hip to

shoulder several times. Place your free hand on top of your working arm and feel the changes

in your arm as the motion changes. Repeat this process several times.

Answer the following questions:

What parts of the arms could you feel working?

Which bones moved and which ones did not?

What parts of your body do you think were working even if you could not feel them?

Part 2:

Lab Activity:

1. Obtain a pair of gloves and a chicken wing for your group in a dissection pan.

Sketch what the wing looks like, identify the upper wing and lower wing.

2. Sketch what a human arm looks like, identifying the upper and lower portions of

the arm.
