Structure, Support, and Movement
By identifying life size model bones, performing a bone dissection, and examining x-rays of
broken bones, students will explore how their skeleton provides structure and support, enables
movement, serves as a mineral reserve, and produces blood cells. Students apply the
scientific method and learn about how the skeleton provides protection by participating
in an egg drop experiment.
Movement, Control, and Coordination
Muscle and Nerve Basics
Students explore the basics of muscle and nerve action through a variety of model building,
role play, and dissection activities. Students examine the basic structure of muscle action
on bones through the dissection of a Cornish hen. Through role play and models, they develop
an understanding of how the microscopic sliding filaments can result in muscle contraction.
The basic organization of the nervous system is also explored. Students also have the
opportunity to test the behavior of their own nervous systems.
