What is bone made of?
A bone is made of collagen. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework.
Aim To investigate the effect of acid on bone.
Method
- We collect chicken bones
- We’re weighing the bones.
- Then we put the bone in it’s own case.
- We put some acids in it. ( we use 3 glasses of syrups).
- We let it to say in it’s own cup.
- Open it, then weigh it.

Observation
|
The bone floated in the water, then it travels around in the cup. Then we open it and it smells bad, lastly we weigh it to measure how much does it weigh.
|
The bone also floated a little bit and it stay in it’s own place. After waiting, we removed the bone in the cup, then test it before we weigh it.
|
I can’t see the bone in the cup because the coca-cola covered the whole glass. After 2 weeks, we open the cup then we removed the bone in the coca-cola and the bone change it’s colour into black.

Conclusion
I think if you put the bone in the acid, the acid will dissolve the calcium in the bone. It will bend the bone in any positone. Then, the bone in coca-cola will also bend because it also contain some acids in it.
