Introduction:
GOAL: The goal of this experiment is to get an egg to bounce.
WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like, but allows the experimenter to have fun in the process.
LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard), and vinegar is an acid. When they both combine a chemical reaction takes place, and carbon dioxide is released. This is what bubbles are made of. The vinegar makes the egg soft because it takes all the carbon out. Since the egg shell is made out of "calcium carbonate" and is "eaten" up by the acidic vinegar. It leaves behind the inner membrane and gives it the rubbery effect.
WHY I CHOSE THIS: I chose this experiment because it was fascinating how an egg that breaks easily, can bounce. My papa suggested an experiment that my neighbor recommended.
HYPOTHESIS: I think that the egg will grow then explode!
PROCEDURE:
LIST OF SUPPLIES:
1.) A clear, see through cup.
2.) 5 cups of distilled white vinegar.
3.) A brown egg.
STEP BY STEP PROCEDURE:
1.) Put the egg in the cup.
2.) Pour all of the vinegar over the egg.
3.) Let the egg set for two-three days.
4.) Take the egg out and see what happened.
DATA AND CALCULATIONS:
Day 1: The egg looks normal and looks like the bubbles are starting to form around it.
Day 2: The egg shell looks like it has started to dissolve and it is floating to the top.
Day 3: The shell dissolved and is floating on the top of the vinegar. The only thing left is the eggs inner membrane.
Observations:
1.) The egg looks like it is see through.
2.) You can see the yoke.
3.) The egg has grown.
4.) The egg looks like its white now instead of brown.
5.) The egg is translucent and very thin.
6.)
