• Put your things on your desk
  

       Book, notebook, pencil case

• Bag on the floor
  
• Read pages 8-10

Lessongoals

• You know the parts of the body
• You can recognize the bones in a picture of a skeleton
• You can name the 4 functions of the skeleton

4.1 Skeleton

You will learn:

- the names of your bones

- the 6(!) functions of the skeleton

- how bones are constructed

- why children move easily

- the functions of your backbone

List functions of the skeleton (answers
seperated by comma's)

6 main functions

*Stability/support

*Protection of vital organs

*Shape

*Movement (with muscular system)

* Storage of fat in long bones (in yellow bone marrow)

*Production of blood cells in flat bones (in red bone marrow)

4 basic parts of the skeleton:

- skull: protects the brain

- spine: carry body weight + protect spinal cord

- rib cage: protect lungs + heart

- limbs: arms & legs (+ muscles) for motion

Let's have a look inside the bone.

Tissue type

- cartillage:

tough, semi-transparant, elastic and flexible

- bone:

hard & (less)flexible
