Egg and Vinegar Experiment ( Darshil Patel and Shivam Gandhi )

•Egg and Vinegar Experiment
•By: Darshil Patel and Shivam Gandhi
•6th Period Biology
•Purpose/Question
What happens when an egg is put inside vinegar with food coloring in it? Can an egg survive a drop after it absorbs the vinegar?
•Materials
1.Egg
2.Beaker
3.Vinegar
4.Food coloring (any color)
5.Something to write on
•Research/ hypothesis
Hypothesis: Through data from a prior experiment, we have learned that the egg will absorb some of the vinegar with food coloring in it. The egg will also lose its shell due to the acidic nature of the vinegar and will only retain a calcium coating. The reason the egg absorbed some of the vinegar is due to osmosis.
Research:
1. The egg’s shell is made up of calcium carbonate. Because of acids, the egg shell will dissolve and give off carbon dioxide.
2. Osmosis is the movement of fluids through a permeable surface. The egg’s shell is a permeable surface
3. The egg is just a giant cell. The shell is the cell membrane. The egg white is the cytoplasm. The yolk is the nucleus.

3. 6th period biology.
•Procedure
1.Fill the beaker with 200mL of vinegar and pour the food coloring in.
2.Put the egg inside of the vinegar to officially begin the experiment.
3.Record all observations. (See what happens to the shell, the vinegar, and the coloring.)
4.Leave the egg in a room at room temperature for one day, out of light.
5.When you come back, record what changes have happened to the egg, the vinegar, and the volume of the vinegar.
6.See if the egg has retained its shell and if its color has changed to the food coloring’s color.
7.Take the egg out and make observations on its texture, weight, etc.
8.Proceed to analysis.
•Observations/ Data
•Pictures
•Conclusion
1.I agree with my hypothesis. The egg did absorb the vinegar. This is clearly shown because the ending volume of the vinegar was 130mL instead of the original 200mL.
2.The egg became the same color as the vinegar. This is due to osmosis. There was also no shell on the egg due to the vinegar dissolving it. The egg also smells like vinegar due to the fact that it absorbed vinegar.
3.There were many variables that couldn’t be controlled in the test. First, the beaker of vinegar could have had an immeasurable amount of light, which means that some of the vinegar could have been evaporated. We could have also pu too much or too little vinegar in.

Fonksiyonel Bir Gıda Olarak Yumurta ( Umran Uygun )

Yumurta, günlük diyetimizin önemli bir parçası olan, kolay ulaşılabilen, protein kalitesi ve çeşidi açısından zengin, kullanımı ve hazırlanması kolay bir gıda maddesidir.

Doğanın bize sunduğu mükemmel bir gıdadır. Eklendiği ürünlerin fonksiyonel değerini arttıran bir gıdadır.

Yumurta ve ürünleri, koagülasyon, emülsifikasyon, köpük oluşturma ve kristalizasyon kontrolü gibi teknolojik özellikleri ile gıda endüstrisinde en çok kullanılan ingrediyenlerdir.

Yumurta, tüketicinin çok fazla gündeminde olan fonksiyonel gıdalar grubu içinde kabul edilmektedir.

Pek çok kurum ve örgüt farklı ‘Fonksiyonel gıda’ tanımı yapmaktadır. Örneğin Gıda Teknologları Derneği (Institute of Food Technologists) fonksiyonel gıdayı temel besin gereksinimlerini karşılamanın ötesinde ek bir fizyolojik yarar sağlayan gıda olarak tanımlamaktadır.

What types of poultry are there?
Ratites-Ostriches, Emus

Pigeons Are Also Poultry
There is a hobby called Pigeon Racing and hobbyists take it very seriously!
The pigeons are released and use their “homing” instinct, to return home to their “lofts”.
Pigeons are also known as “Thoroughbreds of the Sky”

Chickens
Chickens make up the largest sector of the poultry industry.
Consumption of chicken in the U.S. is rising every year.

Why?
Chicken is LOW in fat, HIGH in protein and LOW in cholesterol when compared to meats such as pork and beef.
There are several breeds of chicken used to produce different products and types of eggs.

Breeds of Chicken
White Leghorns
Used for egg production and produce white eggs

Breeds of Chicken
Barred Plymouth Rocks
Used for meat and eggs, produce brown eggs
New Hampshire Reds
Used for meat and eggs, produce brown eggs
White Plymouth Rocks
Used for meat and eggs, produce brown eggs

What is the Difference Between Brown Eggs and White Eggs?
White and brown eggs taste the same and have the same nutritive value. Brown eggs are not healthier!
The color difference is due to the breed of the hen.
You can tell what color egg a hen will lay by looking at her feathers and ear lobes.
A hen with WHITE earlobes and feathers will lay WHITE eggs.
A hen with RED feathers and matching earlobes will lay BROWN eggs.
The difference is purely cosmetic….usually, people in the North prefer brown eggs while people in the South like white eggs.

Broiler- used mainly for meat. A broiler is a chicken is 6 to 7 weeks of age and weighs 4 pounds when it is sent to market.
Poultry Terms to Know

Layer-a mature female chicken that produces eggs. Most can lay 300 eggs/year.

Pullet- a young female chicken

Capon- a male chicken that has been neutered/castrated, usually 5 to 7 months of age and weigh about 6 pounds. By castrating these males when they are 3 weeks old, their meat is more tender and more flavorful when the bird matures.
Poultry Terms to Know

Rooster/Cock- a mature male chicken

Cockerel- a male chicken that is less than 1 year old

Spent hen- a hen that is no longer laying

Poultry Terms to Know

Vertical Integration-raising, processing, and distributing poultry is now one continuous chain. A large company is composed of smaller companies that carry out all the processes from manufacturing to distributing. For example, Con Agra is one large company, but they hire growers, hatcheries, distributors, and processors.

Broiler Production
Broilers are raised for their meat and they make up most of the chicken products that we eat.
A Broiler’s Story:
I was born in a hatchery…then I was placed in an open chicken house where I ate and drank at free will. The chicken house is big, warm, and well ventilated. I ran around on a big open shavings floor. I was fed a diet that made me grow as efficiently as possible so that the grower wouldn’t waste money on me. My diet has yellow corn, soy, other grains, minerals, vitamins, and medicine to keep us from getting sick. My brothers,sisters, and I were all kept very healthy. When I turned six weeks old and weighed 4 pounds I was sent to market so you can enjoy chicken nuggets and other chicken products.

Which three states in the U.S. lead in broiler production?
Georgia, Alabama, and Arkansas
Mississippi, Georgia, and Florida
Arkansas, California, and Michigan
Most farmers grow chickens on a contract.
What does growing on contract mean?
Grower
The Grower Supplies:
House
Utilities
Labor
Shavings
Cleaning Supplies

Company (Con Agra, Perdue,etc.)
The Company Supplies:

Layer Production
Eggcellent!!!!

Layer Production
Did you know?
A layer hen in production can lay almost 300 eggs/year and this number is rising! In 1900, hens only laid 100 eggs/year!

Are the eggs you buy in the store fertilized or unfertilized?
They are unfertilized! Hens do not need a rooster to lay eggs.

Can you name some foods that have eggs in them?
Angel food cake, mayonnaise, egg nog, bread, and noodles are just a few products with eggs!
What are the parts of an egg?

EGG GRADING
Eggs can be Grade AA, A, or B
And
Small, Medium, or Large

Eggs that are misshapen, cracked, or dirty are not sold to the consumer. These eggs are classified as LOSS.
