    I hope this project works out well. I have never done it and I hope that it get me an “A” in science class and takes me to the science fair with a winning prize.

    This is also why you should avoid brushing your teeth right after eating/drinking. The acid will weaken the enamel of your teeth, so you need to wait for it to harden back up a bit before brushing.

        I think that would vary by school and teacher. You’ll have to use your own judgement. It would also depend on your accompanying research, analysis, and discussion.

      No, not at all, that is not true! I work at a dental office and what we tell patients is to please wash or rinse their teeth asap, the acid or sugar will only weaken the enamel if its not rinsed and stays on the tooth… thus the experiment showed, for a total of 24 hours what happened when they did not brush their teeth. Truth of the matter is that many ppl specially children don’t brush their teeth well and sometimes not at all for several days. Which is why children tend to get more cavities.

    Did you use eggs with shells on? And were the eggs hardboiled?
    Can’t wait to do this with my kids.

      Shells on, raw eggs although it doesn’t really matter whether they’re raw or not.

        If I told you, wouldn’t that be like doing your homework for you? There is an independent variable and a dependent variable and a control.

    does it matter what flavor Gatorade you use and what brand the grape juice and black cherry soda you use? and does it have to be that soda? thnx definitely using this for my science fair project!

      It doesn’t matter what flavor of Gatorade you use, but it should be as dark as possible. A lighter color like pink or yellow will not show up on the egg. The only thing is, if you want to get results like what we got, you will want to use sugar-free Gatorade.

      As for the juice and soda, you can use any brand. You wouldn’t even have to use black cherry soda, you could use any dark color like cola or root beer.

    What would be the point of using sugar free if the idea is to see what sugary drinks do to your teeth? And was the egg shell damaged at all by the sugar and acid in the drinks – or did the dyes in the beverages essentially dye the eggs?

    Reply

    • Tara Ziegmont
      March 8, 2018

      The point is to see what sugar-free drinks do to the enamel of the egg. Why wouldn’t you want to test other substances? There’s no reason to limit it to just sugary drinks. It’s interesting to see how the sugar-free drinks react as well.

      To your other question, all three damage the teeth – sugar, acid, and dyes.

      Are you saying that you’re going to use a brown egg? I don’t think that would work very well. White shells show the changes much better than brown ones would.

      the dependent variable is the eggs because they are not changed.
      and the independent variable is the drinks used because they are changed.

    Could I leave this over the weekend and see what happens on Monday? For example, if I did this experiment Friday afternoon and left it over the weekend, would that be too long?

      I don’t think it would be too long. There’s a chance that the eggs in the soda might get a little soft (from the acid eating away at the shell), so you may not be able to use a toothbrush on them, but I’m not sure. The only way to know is to try it! Come back and let me know what happens!

    The acid is what is affecting the shells. Leave them in another day and see how soft they get. Track over time if a few days. Also, have a control that you soak in a fluoride mouthrinse. For a sugar beverage to make difference oral plaque ( bacteria)needs to be present. Certain oral bacteria eat and digest the sugar and then produce an acid that softens the enamel.

    Boiling the eggs makes it easier to handle if the experiment goes on for a few days.

    • Tara Ziegmont

      The control is the one that you don’t do anything to, so that would be an egg in plain water or even just a plain egg that hasn’t been soaked in anything. There is no such thing as a controlled variable. The control is unchanged, and the variable is something that is changed.

    How would you recommend making a graph for this for a Science Fair project? We are stuck on how to show this in a graph. It’s my daughter’s first project. Thank you!

      Hm, a graph? I’m not sure that this lends itself very well to a graph. Maybe a bar graph showing the amount of discoloration? Like, create a scale of 1-5 and rate each egg on how dark its shell got? Just a thought off the top of my head. I really can’t think of anything else though.

    Very excited to do this project. My son is in first grade and it will be his first project as well. He has made a shopping list and everything. Ashley, I hope you aren’t at RES in Mississippi. That would be bad to have two doing the same project. Lol

      November 17, 2019

      It’s sort of doing both. I think, if you left the egg in the soda for longer than a day or two, the shell may eventually get soft. It’s the acid in the soda that does that. I think juice is probably also acidic though not as much as the soda.
