SKELETAL SYSTEM

1. SCIENCE 6 Parts and F unctions of Musculo -skeletal System

2. Have you observed how houses are built?

3. What will the construction worker do first? How will you compare that to the human body ? Is there a framework that provides structure to the human body? What do you call this framework?

4. Activity # 1 C onnect the cut out pictures of the human skeletal system

5. Skeleton Dance https://www.youtube.com/watch?v=e54m6XOpRgU

6. L abel the parts ( Group Work )

7. “What is the purpose of the human skeleton ?”

8. Parts of human skeleton

9. The skeletal system is made up of many bones, 206 to be exact. Bones help to shape your body and protect your organs, such as your heart, brain, and lungs, from damage. If you didn't have bones in your body, you would look like a bowl full of Jello , because there would be nothing holding you up.The framework of your body is made up of rigid and strong materials called bones .

10. Activity #1 : Examining Bone Structure Locate the part of the your framework as I say its name.

11. What are the two division of the skeletal system?

12. What is the difference between compact bone & spongy bone?

13. Why is bone marrow important?

14. Activity #2: Observing Movements of Joints Problem: What are the different kinds of joints? https://www.youtube.com/watch?v=2rUzWx9P7cA Safety Tips: 1. Be careful in moving your body parts, especially your neck and backbone. 2. Do not allow other persons to pull or twist your arm.

15. Mix and Match! Parts and functions of Skeletal System (group work) Your group will be provided with parts(green) and function (yellow) written in metacards

16. Why should bones be strong? Bones support our body and allow us move.

17. How will you take care of your bones? 1.Eat calcium-rich foods

18. 2. prevent from falls and other accidents that could injure the bones especially when playing.

19. 4.Get vitamin D through sunlight ,

20. Your body produces vitamin D naturally when it’s directly exposed to sunlight. Besides getting vitamin D through sunlight, you can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood. Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus, and facilitating normal immune system function. Getting a sufficient amount of vitamin D is important for normal growth and development of bones and teeth, as well as improved resistance against certain diseases.

21. TRIVIA: Bones are alive. They are made of living cells capable of growing and repairing themselves.

22. Our bones are in fact alive! Our bones are made up of hard stuff that gives them the strength they need, and many living cells. These cells are what help our bones to grow and repair themselves if damaged. The cells in our bones rely on blood to keep them alive, just as many other cells in our body do. Did you know that our blood is what brings food and oxygen to our bone cells and takes away the things that our bone cells don't need? If our bones were not alive, a broken bone would stay broken for the rest of our life, because there would be nothing alive to fix it. Luckily our bones are very alive and have the ability to repair breaks and fractures in no time! When we break a bone, our blood clots in the break to form a bridge, or to close up the break.

23. What are the ideas did you learn in the lesson ? What are the parts and functions of the skeletal system ? Describe the potential consequences if all bone tissues in humans were made of spongy bones & no compact bones.

24. Matching type: Match the parts of the skeletal system in column A with the functions in column B. Column A Column B 1. Skull a . the inner layer of the bone that 2. Spinal column contains yellowish substance 3. Bones which manufactures blood cells 4. Hinge joint in the body. 5. Ball and socket b. protects the spinal cord c . a rigid case that protects the brain d . allows movement in all directions e . allows movement in one direction only
