Transcript of Science Project Teeth Stains

Procedure 1. Measure out each liquid with liquid measuring cup to 1 cup (1 cup = 250 mL)
2. Fill each container with each of the different liquid substances.
3. Put one hollow egg in each container.
4. Everyday take out of each egg and record the discoloration.
5.Record and compare the effects of the 4 substances. HYPOTHESIS Due to the coffee being the darkest color substance i would assume that the coffee would stain the most and fastest. Question: Which substance stains teeth the fastest and the most out of Pepsi, Grape Juice, Tea, or Coffee? Materials: 4 raw eggs (hollowed out)
250 mL Welch's Grape Juice
250 mL Folger's Coffee (made through coffee maker)
250 mL Lipton's Lemon Tea ( made)
250 mL Pepsi
4 Large Plastic Containers Conclusion Darker drinks seem to have a dramatic affect on teeth than other drinks but the most being coffee is based on what's it made out of. Coffee is made out of coffee beans which stains your tongue sometimes when you put one in your mouth so it already has a staining affect before it even becomes a drink. Beside the other drinks, coffee is also the only drink made out of one product which means there were no added ingredients to make coffee not stain.
