Students observe the
action of muscles that cause the body to move. Given a number
of facts about muscles, students build operational models to
demonstrate how muscles move legs, thumbs, and arms.
Muscles contract when they work.
Muscles attach across joints to move bones.
Muscles attach to bones with tissue called tendon.
Ligaments attach bone to bone. Some ligaments serve as guides through which tendons run.
Observe the workings of muscles to move bones.
Compare the muscles/bone functions of a model leg to a human leg.
Compare the muscles/bone functions of a model thumb to a human thumb.
