This science fair project was performed to find out if carbonated soft drinks can really cause the erosion of tooth enamel. Testing was done by immersing teeth in Coke, Sprite and root beer for a few days
1. For this science fair project, the independent variable is the brand of soda used to immerse the teeth. The dependent variable is the weight of the teeth. This is determined by checking the weight of the tooth using the digital weighing scale once a day. The constants (control variables) are the size of the bottles, the amount of soft drink in the bottles, the size of the teeth, the temperature of the environment (which will remain at room temperature) and the length of the experiment. 2. Fill the 1st bottle with the Coca-cola, the 2nd cup with Sprite, and .....
