The Unseen World
Saviana O'Hagin

Amy Bonillas

In this project, I studied What Product Whitening Teeth More. My hypothesis was If I use charcoal hydrogen peroxide and toothpaste hydrogen peroxide will whiten more. There are 3 types of variables. The independent variable was Charcoal, hydrogen peroxide and toothpaste. The dependent variable was the whiteness of teeth. The controlled variables were Eggs, bowls, and coffee. The reason I chose this topic is because I wanted to learn more about the whiteness of teeth and which of three products whitens more, Charcoal, Hydrogen-peroxide, or toothpaste.
