Colgate. Soda and Teeth - Is Soda Bad for your teeth, 2012. Web. January 5, 2013.
American Dental Association. Public Resources, 2013. Web. January 5, 2013. Bibliography The purpose was to find what type of soda was the most corrosive. This experiment finds that the darker sodas were the most corrosive. The dark soda removed the tarnish on the penny faster. Results Initial Observations

Summary Experimental Design While the dark soda worked faster to remove tarnish from the pennies, Pepsi did not remove as much tarnish as Sprite. So you can not say that dark soda is always more corrosive than light soda. I believe Sprite removed more tarnish because of the acid from the lemon and lime in it.

What could be done differently is try different coins and see if that makes a difference. Conclusion 10 Means High Tarnish. 1 Means No Tarnish On The Penny Data Analysis Fill each plastic cup exactly half-way with each different soda and one with water.

Drop a penny in each separate cup.

Observe the pennies each day for 7 days and record results in a log book. Procedure Logbook & Pen
Sharpie Marker
6 Plastic Cups
6 Tarnished Pennies
Water (Control)
Coca Cola
Pepsi
Dr.Pepper
Sprite
Mountain Dew Materials The darker colored sodas will be more corrosive to the pennies than the light colored sodas. The water should have little or no effect on the pennies. All the sodas will cause corrosion.

A Colgate.com article researched states that;

“Acids and acidic sugar byproducts in soft drinks soften tooth enamel, contributing to the formation of cavities.” Hypothesis Research by the American Dental Association (ADA) has found that tooth enamel can be seriously damaged by drinking a lot of soda. The purpose of this project is to figure out which type of soda is the MOST corrosive type. It is helpful to scientists and people in the community because it helps people take better care of their teeth and not have to go to the dentist so much. Purpose This topic was chosen because I love to drink Coca Cola. I was curious to see what the effects of my favorite soda are on corrosion. I thought the results were very interesting. By Ryan Gates
