This is a blog for Primary school students, to study science
BONES AND MUSCLES
Let’s remember! First of all, let’s go to remember some importants parts of the body and where are these parts : Head, torso or limbs
- Head: hair, nose, eyes, ears, cheeks, mouth, teeth and tongue.
- Torso: neck, chest, shoulders, belly and tummy.
- Limbs: arms, hands, elbows, fingers, legs, knees, feet and toes.
In this link you can find a Jclic Game to practise with the human body:
To introduce the topic let’s go to see a Power Point about the Locomotor system.
BONES
- A human body has got 206 bones, but a baby can have above 300 bones.
- The skeleton has got two functions:
– Protect the delicate organs
– Supports our body.
- We classify the bones into:
– Flat bones: skull
– Long bones: Femur
– Short bones: Vertebrae
Here you have a amazing video about skeleton and bones.

MUSCLES
- Muscles are soft when relaxed.
- Are connected to bones.
- They move our bones by contracting and relaxing.
- When they contract they gets shorter when they relax they get longer.
- Biceps and triceps work together. When one relax the other contract.
- We have two types of muscles:
– VOLUNTARY: We move them when we want.Brain sends a signal to the muscle They move automatically.
– INVOLUNTARY: We can’t control the movement
when we want to move it. Our heart and some of the stomach muscles are involutary.
If you click on that document you can do differents exercices about body, muscles and bones. Enjoy it!!
We do this mind map all together in class using Popplet, that’s a new tool 2.0 to make mind maps. I hope it will be useful to study at home!
Here we have the final test to download, if you want to do it again.
