I believe coke will affect the eggshell the most because it has the lowest pH (most acidic) compared to Seven Up and Canada Dry. Since acid can dissolve calcium (which eggshells are made of), I think the Coca-Cola will cause the eggshell to break down faster than the other two drinks

We learned that a carbonated drink  has the chemical formula H2CO3 and the extra mix is the reason it is less dense than water. We also learned that Eggshells are mostly made of calcium carbonate (CaCO₃), which makes up almost 95-97% of the shell. The rest is made out of of proteins, such as collagen, and minerals.eggshells have tiny holes which makes the eggshell fresh. When eggshells come into touch with acids, a chemical reaction happens where the calcium carbonate reacts with the acid, releasing carbon dioxide Stronger acids (like hydrochloric acid) will dissolve the eggshell faster than weak acids (like vinegar or lemon juice). Soda’s have chemical ingredients that deteriorate things.This happens because of the acidity of the soda which makes the item slowly lose its texture

1. Make a hypothesis
2. Experiment trial 1
3. Trial 2
4. Trial 3
5. Make a conclusion analyse results
6. Repearsent results(graph,chart ext,)

I observed that the coke was the most acidic,due to it making  the most impact on the shell because of the of calcium carbonate CaCO₃, which makes up almost 95-97% of the shell. The rest is made out of of proteins, like collagen, and minerals.

 Trial 1-coke-Most acidic

   Trial 2-sprite most acidic 

   Trial 3-coke most acidic

the coke was the worst for your teeth i learnd that drinks may not be a smart investment for your future health growing up 

Carbonated drinks like Coke, Seven Up, and Canada Dry can affect your teeth because they are very sugary and acidic. The acid in these drinks can wear down the enamel (the hard outer layer of your teeth), and the sugar can cause cavities

i couldve cracked the eggshell more even bbut only a robot has that much precision to crack a eggshell perfectly done the middle 3 times
