Description of New Content

Representing the human arm as a model, mechanisms that allow us to move

Teach basic construction skills and problem solving as well as illustrate the movement of joints and muscles in the arm. Also, the names of the bones and muscles in the arm will be reinforced.
Materials Needed

String, Paper towel tube, masking tape, small white straws, large straws, paper, scissors, Muscle Model Worksheet (pdf format)





Opener - How can we show the movement of our arms using carboard, string, and tape?

Development - Follow worksheet and allow students to work through challenges as they build their models

Closure - Have students label the type of joint and name the 'bones' and 'muscles' in their arm model



Arm model labeling and construction

Allow students to make models of other types of joints found in the human body (such as ball and socket) and label the muscles and bones in those models as well
