How Does Calcium Affect Your Bones and Health?

Overview

Objectives/Goals The project's goal is to show what happens to bones that get too much calcium, too little, just enough, or none at all. Methods/Materials Materials: jars, cooked chicken bones, masking tapes, gold scale, vinegar, water, calcium tablets, paper, measuring cup, scissors, knife. Methods: Get six cooked chicken bones each weight about the same. Label each jar from 1 to 6. Fill each jar with its contents: Jar 1 - water, Jar 2 - vinegar, Jar 3 - vinegar and one calcium, Jar 4 - vinegar and two calcium, Jar 5 - vinegar and three calcium, Jar 6 - vinegar and four calcium. Put one bone in each jar. Observe the bones' characteristics for about two weeks. Test the bones' strengths with hands and knife. Results Bone 1 was the strongest, bone 2 was the weakest, bone 4 was the strongest one in calcium. Conclusions/Discussion Bone 1 was the strongest since vinegar destroyed the rest of the bones (bones 2 to 6). However, bone 4 was stronger than the other calcified bones because it got the right amount of calcium. Too much or too little calcium will damage your bones.
