Got a Bone to Pick

Overview

Objectives/Goals My goal was to answer the question "Can Bones resorb calcium". My Hypothesis was yes, bones can resorb calcium. Methods/Materials First I decalcified the bones using Vinegar, is 6% Acetic acid (CH(3)COOH). Then I used Calcium Oxide (CaO), Pickling lime, to provide the calcium for the bones to resorb. I used chicken bones to conduct the experiment. Results My results showed that all the bones, when put in Vinegar, lost their calcium; the calcium in the bones reacted with the acetic acid and formed calcium acetate. Later on in my experiment I noticed that pickling lime, calcium oxide, helped the bones regain calcium. I also noticed that not all the calcium lost was regained. Conclusions/Discussion My hypothesis was correct. From my research I learned that osteoporosis is a disease that causes bone loss. Bone loss is the loss of calcium and minerals in a bone. I found that bone density is how tightly packed bones are or how many minerals are in a bone. I also learned about prevention methods and medication for osteoporosis.
