1. Is there a pattern to your graph? (Increase, decrease, or same)

- How many bones did your model need?  How many muscles did it need?
Our "model"  needed 3 bones, Ulna Radius and Humerus. Muscles, I dont know maybe 3?
- How were your pretend muscles similar to real muscles? Different?
Well real muscles weren't covered in tape and string.
- What changes occur to the real muscles in the human body to make them pull on bones?
The real muscles contract, or get smaller, they don't have hands pushing them.
- What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate?
It wouldn't allow the muscles to bend or move what so ever.
