1 How many bones did your model need? How many muscles did it need?
2 How were your pretend muscles similar to real muscles? Different?
3 What changes occur to the real muscles in the human body to make them pull on bones?
4 What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate?
1 Our model needed three bones. The tibia, fibula, and humerus.
2 They were really not. They were different because our bicep was on the for-arm.
3 The muscles change by relaxing or contracting. The muscles got smaller and flex by contracting and they relax by stretching.
4 Yes because it would not pull. This is a problem because it would be a lot harder to move.
