= How Different Liquids Affect Eggs =

Broad Question
How do different liquids affect eggs?

Specific Question
How do different liquids affect eggs after soaking for a two week period?

Hypothesis
I predict that the soda will dye the color of the eggs and not effect the weight too much, however I think other liquids will eat away at the egg and make the weight decrease by a lot.

Variable
The different liquids that the eggs will be soaking in

Independent Variable:
Liquids.

Dependent Variable:
Eggs.

Materials List:

 * 1) About 6 eggs
 * 2) About 6 jars
 * 3) Milk
 * 4) Vinegar
 * 5) Apple Juice
 * 6) Any soda
 * 7) Orange juice
 * 8) Cool Aid

Variables That Need To Be Controlled:
Eggs, jars, amount of liquids.

Experimental Design
The first thing that I have to do is mass out the weight of the jars, the different liquids, and the jars with the liquids in them, and also mass out the weight of the eggs. After I do that I have to place the eggs into the jars with the liquids in them. Once the eggs are in the Jars I have to make sure that the eggs are in the jars with the lids tightened relatively tight. Then for the next two weeks the jars are going to be in the fridge for the next two weeks. After the eggs soak in the liquids for two weeks I’m going to mass out the weight. One that is done all I have to do is subtract the weight off the jar and the liquid and I should be able to tell the difference between the original egg and the egg after it soaked for two weeks. Then I will mass out the weight of the eggs after soaking for two weeks with a scale and see how much the liquid changed the mass of the egg.

Background Research
Egg shells contain something called "calcium carbonate." This is what makes them hard. Vinegar is an acid known as acetic acid. When calcium carbonate (the shell) and acetic acid (the vinegar) combine, a chemical reaction takes place and carbon dioxide (a gas) is released. This is what the bubbles are made of.

Detailed Procedure

 * 1) Mass out the weight of the eggs, jars and different liquids.
 * 2) Place the different liquids into the jars.
 * 3) Put one egg into each of the jars.
 * 4) Tighten the lid of the jars.
 * 5) Place the jars into the fridge for 2 weeks.
 * 6) Mass the weight of the jars with the liquid and the eggs.
 * 7) Subtract the two weights and record the differences.
