The human body is born with over two hundred fifty bones, as the body ages the bones fuse together into over two hundred bones. These bones can vary in structure and all have multiple functions depending on the location and purpose. Long bones may be positioned with other bones as a ball and socket, while flat bones can act as hard plates like the skull which acts as a case for the brain. Our nerves send messages throughout the body to do everyday functions such as walking, talking, and eating. Bones are made up of organic and inorganic minerals and later weakens through time. The human jaw is made up of the maxilla, or upper jaw, and the mandible, or the lower jaw. The frontal area of the maxilla is called the hard palate and the soft

Eggshells are made up of a brittle white substance called calcium carbonate, which is also found in cave stalactites. Along with calcium carbonate is the remaining five percent calcium phosphate, magnesium carbonate, and soluble and insoluble proteins (Senese, 2010). The shell is covered with over seventeen thousand tiny pores allowing air to pass through. The semipermeable membrane covering the outer and inner shell membrane has an outermost coating called the cuticle to keep bacteria from entering the pores (Nelson, n.d.).
The experiment will be conducted to determine which acid or base corroded most of the eggshell in the given amount of time. There will be a control group placed into water to compare to the variable groups Diet Coke, Red Bull, and lemon juice. The dependent variable is the amount corrosion on the calcium carbonate of the eggshell, measured by the scale in milligrams. The test groups will all be put into an environment at a constant temperature, and checked on daily to observe the eggshell corrosion. After the test is finally complete, the information gathered over time will be evaluated and conclude which acid or base corroded the most of the eggshell.
If eggshells are soaked in Diet Coke, Red Bull, and lemon juice, then the egg shells will get corroded the most by the acids contained in
