Post about your observations and explanations for our At Home Egg Challenge.

Would love to see your photos too!]]> 2021-05-06 19:25:11 UTC https://padlet.com/kristawilson2/w4z2saf6bucefzh0/wish/1499865333 My egg experiment-Preetham.M preethammoparti https://padlet.com/kristawilson2/w4z2saf6bucefzh0/wish/1506924583 Hi everyone. I finished my experiment with the egg and vinegar. Here is what I noticed.

Observations: 

-When I first put the egg in I saw immediate reaction! There was tiny bubbles that were attached/struck on the egg! At the end of the experiment, I saw some foam on top of the vinegar.


Explanations:

-My Theory: I thought that the  vinegar broke down the shell of the egg. (This might be because vinegar is a acid.) In the process it causes the bubbles to form. The bubbles might be the shell breaking up and floating up to the top. It is not the shell that's breaking up because I could see the shell attached to the yolk. It might be the hardness of the shell that's breaking up. The shell softens by this so I washed it and saw a weird type of yellow substance. The egg was also squishy. 

-The real reason: I did some research and found the scientific reason why this happened. Eggs contain "calcium carbonate".  This is what makes them hard.
Vinegar is an acid. When we mix these two substances a chemical reaction takes place and carbon dioxide (which is a type of gas) is released.  The carbon dioxide are the bubbles. This reaction keeps on happening until on day. This is when all the carbon is used up. When you take the egg out of the vinegar, the egg is soft because all of the carbon floated out of the egg in those little bubbles.

So that way my experiment! Hope you learned a little bit more about this experiment.
