Procedures:
1.Select two different types of toothpaste.
2.Take a picture of your teeth before you begin to brush.
3.Brush your teeth twice a day for two weeks. Make sure that you brush for two minutes and you use the same amount of toothpaste on your toothbrush.
4.When the two weeks is up, take a picture of your teeth and see how white they are.
5.Select the other toothpaste that you did not use.
6.Repeat steps 2-4 again.
7.Take the two pictures and see which toothpaste made your teeth whiter.
Data: The data shows that Colgate whitened my teeth better than Synsodyne in both of the weeks. On the first week, when I used the Colgate, my teeth were looking white.The whitness for the first week was an 8 which was pretty good for being white. On the second week, I maked it as a 10 becasue they were looking much whiter than the prevous week. When I began to use the Synsodyne, I was not real impressed with the whitness on the first week. I marked it as a 6. I notcied as the week went on, I saw a little inprvement, but not as much as the Colgate did, so I marked it as an 8 Overall, my teeth were whiter when I used the Colgate.
Conclusion: The data did not support my Hypothesis. I now claim that Colgate whitens your teeth better than Synsodyne. I know this is true because my teeth were whiter after I used the Colgate than when I used the Synsodyne. The reason this happend is because I found out when I was reading the ingredients, Colgate has white strips, which make your teeth whiter. The stips provide whitning ingredients which helped the toothpaste get a better cleaning. The Synsodyne did not have the stips, so my teeth were not as white.
Discussion: I could have done a lot of things better while I was doing this experiment. I think that I should have done the whole testing part a little longer. My teeth might have gotten whiter if I had used more toothpaste on my teeth. I also think that I could have obrused my teeth for a little bit longer too than the 2 minutes that I did. I think that a month would have been the best for this.That way, I could have saw what my teeth looked like over a longer time. I also think that I could have had other family members to test it too. Maybe if I would have did it that way, people might have gotten different results and I could compare all of them when I was done with the experiment to see what the most accurate results were.
