Title
Eggs Density

Problem Scenario
What happens when you overcook an egg?

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

Specific Question
How does cooking time effect a eggs density?

Hypothesis
It is hypothesized that the cooked egg for 80 minutes, will be less dense.

Independent Variable:
Time cooked

Dependent Variable:
Density

Variables That Need To Be Controlled:
Heat, size of egg, and the amount of water.

Vocabulary List That Needs Explanation
Density: The mass of a substance per unit volume

General Plan
I am going to boil 1 1/2 cups of water for certain amounts of time then put 4 eggs in each 5 time periods. Then once the eggs are cooked I will measure their density using a balance, an overflow cup, and a graduated cylinder. Then I will record the density of each egg and find the average between them.

Potential Problems And Solutions
-The egg could overcook -Something could catch on fire -The water could rise over the pot

Safety Or Environmental Concerns
- Getting burnt - Break egg - Catch on fire

Number Of Trials:
5

Number Of Subjects In Each trial:
4

When data will be collected
March

Number of Observations:
one observations for each subject

Where will data be collected?:
The data will be collected in my science journal

Time Line
I am going to boil the eggs at night so in the morning i can bring them to school and measure the density. then, the next night I'm going to do that data table and the graph. Then finally, i am going to make my poster about my project and what i did.

Background Research
Eggs consist of protein and amino acids. They are produced by hens and the variance of eggs can be determined on how the hen is fed. To boil an egg you put water in a pot and start to warm it. next gently put the eggs in the pot and wait 20-30 minutes till they are done. then carefully take them out and dump the water.

Detailed Procedure
I will boil water with eggs for 0, 20, 40, 60, and 80 minutes at home and bring it to school in the morning. After I will measure the weight and density of each egg using a measuring cylinder, and a measuring weight and record the data in my science journal.

Conclusion
From the data I collected, I discovered that the amount of time you cook an egg does not effect the density of the egg. As shown in my results of the egg density average, they all are about the same amount of density. My hypothesis was incorrect because i predicted the egg for 80 minutes would be less dense.

Discussion
This data showed a pattern that it would start to go down, but then came back up. The relationship between the independent and dependent variables is not strong. I was able to answer my question, but it wasn't the results i was looking for. The data went by smoothly, only breaking some eggs making me have to restart, but the collection of the data went on task. This data could help people if they needed to make an egg a certain amount of depth and then they would realize that it will always be pretty much the same amount of dense. I couldn't really use this information in the real world unless i were to have some sort of egg contest. This experiment could be more advanced if there was a greater time cooked difference. I don't believe my results would benefits science or the economy.

The question that was trying to be answered was, how does cooking time effect an eggs density. The hypothesis that was made was the more time you cooked an egg, the less dense it gets. The answer to the question was that the cooking time doesn't effect the density. I collected my data at home by boiling 4 eggs at 5 different time periods; 0 min., 20 min., 40 min., 60 min., 80 min. Then I brought them to school and measured their weight in grams and their density in milliliters. I wrote my data down in my science Journal.
