  1. Skeletal System Activating Strategy: Please Do Now… • Please turn to p. 9 in your packet. • Using your prior knowledge about the parts of a bone and the types of bones found in the human body, answer the following question: What does our skeletal system do? (list 3 things)

  2. Skeletal System LEQ: What is the purpose of the skeletal system?

  3. Skeletal System Integrated Literacy: Shared Reading Functions of the skeletal system (p. 10) Read and mark the text by placing the numbers 1-6 beside each function of the skeletal system. Student Activity #1: (pp. 11 and 12) Complete the graphic organizer: Functions of the Skeletal System by creating a metaphor of the functions and providing an example of a bone that functions this way.

  4. Skeletal System Functions of the Skeletal System: Support Metaphors: tent, roof trusses, pillars, steel beams, tree roots, spine of a book, a cast, legs on a chair or desk, picture frame, and a cane or walker

  5. Skeletal System Functions of the Skeletal System: Protect Metaphors: a helmet, armor, watermelon shell, a book cover

  6. Skeletal System Functions of the Skeletal System: Assist in movement Metaphors:backhoe, drawbridge, conveyor belt, see saw, and roller blades/hoverboard, crane

  7. Skeletal System Quick Check for Learning: • How do the pillars of a porch function like the long bones of our body? • How does a helmet function like the flat bones of our body? • How does a drawbridge function like the bones of our body?

  8. Skeletal System Functions of the Skeletal System: Store minerals Metaphors:refrigerator, storage shed/box, gumball machine, bank vault, silo. ALL BONES

  9. Skeletal System Functions of the Skeletal System: Produces Blood cells Metaphors:generator, factory, windmill, a cow, chickens, trees, flowers

  10. Skeletal System Functions of the Skeletal System: Stores energy Metaphors: solar panels, hard drive, power plant, transformers, batteries, windmill LONG BONES

  11. Skeletal System Quick Check for Learning: • How does a silo function like the bones of our body? • How do trees function like the flat bones of our body? • How solar panels function like the bones of our body?

  12. Skeletal System Summarizer: Ticket out the Door Type II Writing: Write a paragraph to explain the purpose of the skeletal system?

  13. Skeletal System LEQ: What are the responsibilities of the bones of the skeletal system?

  14. Skeletal System Lesson Activator: Think/Pair Share Name as many bones of the human skeleton as possible. Count your total.

  15. Skeletal System Introduction: There are 206 bones in the skeletal system of an adult. But when the skeleton initially forms in the body of a fetus, it is made of 270 pieces of soft cartilage, not bone. Eventually the cartilage is replaced by hard calcium. The process is called ossification, and it takes about 20 years to complete. Bone building continues throughout your life because bones are a living part of your body.

  16. Skeletal System • Axial and Appendicular Skeletal Review

  17. Skeletal System Divisions of the Skeleton: • Axial skeleton– consists of the skull, the spine, the thorax (torso) and includes 80 bones. It supports and protects the organs of the head, neck, and trunk. Regions of the body: • Skull, thoracic region, vertebrae or spine Specific examples (bones): • Bones of the skull, ribs, sternum, and vertebral column

  18. Skeletal System Divisions of the Skeleton: • Appendicular skeleton- bones that anchor the appendages to the axial skeleton and their attached limbs. (126 bones) Regions of the body: • Shoulder girdle, pelvic girdle, and appendages. Specific Examples: • Scapula, clavicle, humerus, radius, ulna, carpals, phalanges, pelvis, femur, tibia, fibula, tarsals. • scapula, clavicle, femur, tibia, fibula, patella, carpals, tarsals, phalanges, humerus, ulna, radius

  19. Skeletal System Summarizer: On page 19 complete the student activity by coloring or shading in the bones of the axial skeleton and the bones of the appendicular skeleton. Provide at least 3 examples for each part.

  20. Skeletal System Lesson Activator: • In your notes, write three things that you know about bone structure (refer back to your KWL chart or to the short “You Tube” clip that we saw at the end of our last class).

  21. Skeletal System Preview Vocabulary: • Ossification There are 206 bones in the skeletal system of an adult. But when the skeleton initially forms in the body of a fetus, it is made of 270 pieces of soft cartilage, not bone. Eventually the cartilage is replaced by hard calcium. The process is called ossification, and it takes about 20 years to complete. Bone building continues throughout your life because bones are a living part of your body.

  22. Skeletal System Structure of a Bone: • Bones are hard on the outside and have spongy tissue inside. • The spongy tissue produces blood cells for the circulatory system. • Bone tissue is alive and made of cells. It is always being destroyed and remade, especially while you are still growing.

  23. Skeletal System Introduction: There are 206 bones in the skeletal system of an adult. But when the skeleton initially forms in the body of a fetus, it is made of 270 pieces of soft cartilage, not bone. Eventually the cartilage is replaced by hard calcium. The process is called ossification, and it takes about 20 years to complete. Bone building continues throughout your life because bones are a living part of your body. There are 5 different classifications or categories of bones in the human body. Today we are going to identify them and explain what they do. Turn to page 7 and 8 in your packet.

  24. Skeletal System Structure of a bone: The structure of a bone can be looked at when viewing a long bone such as the femur. • A long bone is one that has greater length than width.

  25. Skeletal System Functions of the Skeletal System: • Bone is often stereotyped as simply a protective and supportive framework for the body. Though it does perform these functions, bone is actually a very dynamic organ that is constantly remodeling and changing shape to adapt to the daily forces placed upon it. Moreover, bone stores crucial nutrients, minerals, and lipids and produces blood cells that nourish the body and play a vital role in protecting the body against infection. All these functions make the approximately 206 bones of the human body an organ that is essential to our daily existence.
