Grade 8 Human Systems

 * Purpose:** This section introduces students to the major organs of the skeletal system and describes the function of bones. This section also describes the internal structure of bones and compares and contrasts sliding joints, hinge joints, and ball-and-socket joints.


 * Activities:** When participating in the unit, the students do simple motion exercises to examine the movement of the human skeleton.


 * Alternate Activity:** Students respond to the following scenario: "Did you ever break a bone? Do you know someone who broke a bone? Tell us what happened, and how the bone break was mended. Describe all features of the mending process, including how the bone tissue is repaired. Present the report in the medium of your choice."


 * Resources:** The students use the [|Human Body Systems and Health] text by Holt, Reinhart, and Winston for one source of information. However, the primary sources of information are retrieved from the following websites:
 * [|The BBC Interactive Human Body]
 * [|The Virtual Body]
 * [|Bones Quiz]
