I saw this craft and I loved it! We did it in classes and my students liked it too. I prepared a pdf with the materials you'll need and some skulls you can use to make the craft. If you want, you can try labelling the main bones of the body.

This "booklet" is a synthesis of the representation, function and components of the different systems of our body. Each page should be cut and stappled from the top so that each tab is a different system. 
It is in Word format so it is editable.
