1.Describe the data you collected and observed in your experiment. The use of data tables,charts, and/or graphs are encouraged.Some of the data we collected, for example was the soda Sunkist made the tooth red. The soda Sunkist also had effect on the tooth by changing from being a number 2 on the tooth whitening chart from being off the chart red. The next soda we used was sprite and it made the tooth white, it even made the tooth cleaner. Even though the sprite made the tooth cleaner it will eventually lead to cavities because it has high acid level and fructose corn syrup. Sprite doesn't have lots of food coloring, therefore that's why it didn't change colors. lastly our soda Coca-Cola was a number 2 in white when we started ( 1 being most white and 13 being least white) then after the 3 days its was a 13 according to the chart. The color changed to a brown even some black in it. Coca-Cola had a big effect on the tooth, because that soda had the most food coloring and acid compared to the other sodas.

2.Analyze the data you collected and observed in your experiment. Does your data support orrefute your hypothesis? Do not answer with a “yes” or “no.” Explain your answer using one ofthe following prompts: “Our data supports/refutes the hypothesis because .. .”The groups data refutes the hypothesis because we predicted that the tooth in Sunkist would be darker, but not as dark as the color red. It also refutes our hypothesis of the sprite because we predicted that it would darken the tooth not whiten it. Our results also support our prediction that the Coca-Cola will change the tooth brown which it did.
3.Explain any sources of error and how these could have affected your results
A source of error was that we forgot to use water in the experiment. Using water in our experiment would have effected it by giving a contrast between water and soda. This would have possibly changed our experiment drastically or minimally. Another source of error was that we did not test our experiment more that once (the scientific method(3)). This could have effected our experiment if we did something incorrect it could have changed our results and the data would be more accurate. Lastly, a source of error was that we didn't have all our materials because we were supposed to have 4 sodas, but we only had used 3. This is a source of error because it minimizes our amount of results.
