Funny science at School

Learning with DIY: 

THE SKELETAL APPARATUS!

Here a little project to do with children,
at school or at home, they all having fun :-)

You need: cardboard, white pencil, scissor, some Paper Fastener and a bit of yarn.  

And, of course, an image of the skeletal apparatus to copy on the cardboard.

First: draw your skeleton, color it with white, then cut out it and 
assemble all the pieces with the Paper Fastener. 

At last insert the yarn as the tendons. 

What's the function of skeleton & tendons? how their operate?

 Try to move the arm of your skeleton model pulling or stretching the tendon... look! 
As you can see, the bones supports the "body" and they can move thank to the tendons (and muscles!). Tendons often work together but in opposite mode: 
when one is tense the opposite is extended.
Ok, you have finish!

 Now you can explain the operation of skeletal apparatus even to your granma :-P
