Human Body

Concepts of Human Body Teachers want to keep these ideas in mind throughout the unit to help guide instruction and to emphasize with learners.  Bones A human body can move in many ways.  Movements are aided and limited by bone and joint structures. Bones have a variety of forms. Bones have three major functions in the human body:  support, protection, and locomotion. Joints The human body has an articulated skeleton ready for action. The structure of a bone is related to its function. The human skeleton has three types of joints:  hinge, ball-and-socket, and gliding joints. Muscles The main function of muscles is to provide movement. Muscle tissue contracts when it works. Muscles provide coordination and structure for the body. Muscles attach to bones with tissues called tendons. Coordination The action of bones, muscles, and central nervous system working together is called coordination. A stimulus is an event that triggers a response.  It is often information received through the senses. A response is a reaction to a stimulus. Response time is the length of time between a stimulus and a response. Inquiry Skills Inquiry skills are those skills students use to make sense of their science investigations.  They tell what the students will actually be doing in science.  The Inquiry Skills for Habitats are:  Observe Record Collaborate Measure Explain Explore Quantify Communicate Predict Infer Question Apply and Connect
