This is me and Charlies Model of a working elbow!
Reflection:
This experiment was very fun for me, and I think for Charlie too! We had a lot of fun, and it was really tricky at points. One of the hardest parts were figuring out what we had to do to make the elbow pull both ways! I really liked the model at the end of the project! For me, this was one of my favorite experiments!

- 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? | 1. My model needed 2 bones and 2 muscles. The bones were the Humorous and the ulna. The muscles were triceps and the Biceps. 2. My pretend muscles were similar to real muscles because they pulled and didn't push. 3. The changes that occur to the human body to make them pull on bones are that they contract and then relax. 4. If the ligaments on the model were torn, then the muscles would be falling off. Also, the model wouldn't work the way it should. |
