Eggs Experiment


Today we had an experiment, involving eggs and different substances. We had to learn about osmosis and other ways that cells maintain homeostasis. I was put into a lab group with two of my friends and we were started.
First we had to put three different eggs in 100 mL of vinegar. We let the eggs sit overnight. The next morning, during class, the eggs were ready for the next step. We had to peel away the outer shell which was now soft, thanks to the vinegar. We were supposed to be very careful, for the inner membrane of the egg was still quite fragile. That mission was unsuccessful, since one of my lab mates brutally murdered the poor little egg membrane.
The other two eggs we let soak in different substances. The first egg we put in 100mL of corn syrup. The second egg we saturated in 100mL of Coca Cola. We let the two eggs sit in their substances for twenty-four hours once again.
The next day in class we looked at our eggs again. The egg that was soaked in corn syrup had swelled up to a disgusting proportion. The other egg- the egg soaked in Coca Cola- had turned brown instead of semi-transparent and it shriveled up. The next thing that we did was put the first egg in 100mL of alcohol and let it sit overnight.
The next morning in class we examined our eggs for the very last time. The eggs had turned extremely gross- in technical terms. The liquid that was inside the egg had turned gelatinous. Our teacher told us that was what happened to children with Fetal Alcohol Syndrome, and my heart dropped. It was really sad to learn about about such things and my heart goes out to all the children who must suffer for such things.
