Calcium in Bone Activity



The boys examined an old chicken bone and noticed how hard it is. We then put it into a cup of vinegar. We will check on it later and see what happens to it.
About a week later, we took it out and found that the vinegar leached the calcium out, making the bone soft and rubbery.
