| Abstract | I picked this project is because I recently found out that Mountain Dew |
| has a natural citric acid rather than the other soda companies who use |
| artificial acid. I want to test the effects of the soda on how it changes |
| our teeth. |
| |
| Materials: Pelletized Limestone (simulated teeth), Eggs (Hard Boiled), |
| Mouthwash, Toothpaste, Coca Cola, Mountain Dew, Faygo Red Pop, |
| Diet Coca Cola, Water |
| |
| Questions: |
| 1.)How does the soda effect the teeth (limestone)? |
| 2.) Does a mouthwash or toothpaste solution make a difference with the |
| testing of the teeth (limestone)? |
| 3.)How does the same soda effect the staining of the teeth (Boiled |
| Egg)? |
| |
| Prcedure: |
| 1.) Weigh the Limestone's beginning mass and record it. |
| 2.) Put 1/3 of the limestone in the mouthwash solution for varying |
| amounts of time. Put 1/3 of the limestone in the toothpaste solution for |
| varying amounts of time. Leave the remaining Limestone in water for |
| varying amounts of time. |
| 3.) Re-weigh the limestone and record it. |
| 4.) place the limestone in soda for varying amounts of time. |
| 5.) Weigh the resulting Limestone and record it |
| |
| Hypothesis: |
| I believe that the natural citric acid found in Mountain Dew will decay the |
| teeth faster and will also stain the most. |
