This way you can figure out whether what you are observing comes from the fact that the tooth/eggshell was soaked in a liquid or whether it is actually something about the liquid that causes what you are seeing. Scientific researchers recognise that teeth would not be soaked in drinks for hours at a time and saliva has an impact on the results. The acidic vinegar breaks down the minerals in the egg’s shell just as the acid does to the outer shell of our tooth.

I got my result 3 days after and the turned out like this. We found our toothpaste covered egg stained less than the non toothpaste covered egg. Results of our tooth decay experiment with egg shells.

Their Teeth Can Be Stained And Even Worse, Eaten By The Acid Produced By Bacteria.


This egg was in the dark soda. Continue with and complete the eggshell investigation from the last session. It was clear and maintained its color.

Leave The Eggs Over Night, Keeping An Eye On Any Changes!


The children are able to explain how the enamel from our teeth is very similar to the outside of an egg, both needing calcium to. To perform this experiment i had to gather all of the materials that were required, once i got the grape soda, lemonade, needle, eggs, mason jar, measuring cup. You should see staining on both the fizzy drink and tea/coffee egg.

Label Each Cup With The Liquid And Carefully Add A.


The tea cracked the egg and made the colour of the shell darker. Comparing the teeth/eggshells soaked in the different liquids to a “control” tooth/eggshell soaked in water gives you a more accurate baseline. This is how soda stains our teeth.

Interestingly, Red Bull And Gatorade Begin To Bubble And Dissolve The Eggshell As Soon As The Egg Was Put Into Each Of Them.


5 pint glasses or similar container; The vinegar completely dissolved the eggshell, leaving just the membrane behind. Use the printable version link at the top of this page to print copies of this experiment.
