Broad Question
How much salt will it take for an egg to float?

**Specific Question**
Does the size of an egg effect it's density?

Hypothesis
The size of the egg will affect the density. The larger egg will have more density.

Independent Variable:
Size of egg

Dependent Variable:
Density

Variables That Need To Be Controlled:
Size of an egg

General Plan
The first thing that I will do is weigh each eggs mass. Next I will drop the egg into a cup of water. Then I will push the egg into the water until the water is over flowing the cup. Once the water is over flowing the egg I will take a graduated cylinder and measure the amount of water.

Potential Problems And Solutions
An egg could break, which means that I will have to have extras.

Number Of Trials:

Number Of Subjects In Each trial:
3

When data will be collected:
Mid March

Number of Observations:
1

Where will data be collected?:
At school

Background Research
I did a lot of background research. All of it has something to do with my project which involves eggs. Also a little about density, mass and volume.

The "density" of something is a measure of how much it weighs per amount of space it takes up. The formula for density is mass divided by volume.

Mass is the amount of space that an object takes up, which causes it to have weight in an area with gravity. Volume is the space of a three-dimensional that is filled with some sort of liquid.

The average density of a medium egg is 1.10 ml. The average density for the large egg is 1.20 ml. Last but not least the extra large egg's average density is 1.50 ml. The average mass for a medium is 53. The average mass for the large egg is 75, and for the extra large is 83.

After doing all of this research I have found a lot about all the three different sizes of the eggs. Like the average density, and mass of medium, large and extra large.

Detailed Procedure
Step 1: Take 1 egg and put it on the mass Step 2: Record the mass Step 3: Take the egg and put it into a cup of water Step 4: Then I will take the egg and put it in an over flow cup Step 5: I will then push the egg until it is all the way underwater Step 6: Then I will get a graduated cylinder and put it under the water that is pouring out Step 7: After that I will record and calculate the the density of the egg Step 8: Then I will repeat steps 1-7 for the other three sizes

Conclusion
After doing my experiment I have found an answer to my specific question. The size of the egg does not affect the density. The first graph shows in trial 3 both medium and ex-large have a greater density than large. Then if you look at the second graph it shows how the correlation between them is extremely weak. Because of the weak correlation the density of the egg and the size of the egg have no relationship between the two.

Discussion
One pattern that I have noticed through out my data is, that the medium and large eggs have very close density out of all three trials. However, the extra large egg has more density than the others. The scatter plot graph shows this pattern. The experiment did not have any problems or errors. However, this experiment could be improved upon by doing more trials to make the data more accurate.

Benefit to Community and/or Science
One benefit is that a store owner could price their eggs based on the size of their density.

Abstract
For my experiment I tested, does the size of an egg affect of it's density. It is hypothesized that the size //will// affect the egg's density and that the extra large egg will have more density. My hypothesis graph shows that the extra large egg will have the most density out of all of the other eggs. When I did my background research I found out what the average density was for a white egg. For a medium egg the average density is 1.10 ml. For a large it is 1.20 and for the extra large it is 1.50 ml. I also found out what the definition for density, mass and volume is. My general plan was to find out the eggs mass, and volume. Then once I found those two I divided them to get the density of the egg. The results did come out the way I thought they were. In the scatter plot graph the average density of the medium and large egg were so close that they look the same. On the other hand the extra large looked like it had more of an average density than the other eggs. In the end the extra-large egg did have more of an average density than the others.
