- How many bones did your model need? How many muscles did it need?
- How were your pretend muscles similar to real muscles? Different?
- What changes occur to the real muscles in the human body to make them pull on bones?
- What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate?
-It needed three because bones, the Humorous the Ulna and the Radius but we used two paper towel roles, one represented both the Ulna and the Radius and the other for the Humorous.
-Well they both do the same thing and that's how they are simaliar and they are different because our arm isn't made of cardboard and pipe cleaners.
-I know that it would not operate without them and the arm would mostly fall appart. (I know this because it happened!)
