Title
Brown Apples

Problem Scenario
Somebody would want to study this because it could help them keep apples more fresh for a longer time.

Broad Question
How can i prevent a apple from turning brown.

Specific Question
How can i prevent a apple from turning brown

Hypothesis
I predict a apple will brown slower in a Tupperware container **Variables**

Independent Variable:
Storage method.

Dependent Variable:
How brown it gets.

Variables That Need To Be Controlled:
storage method

Potential Problems And Solutions
I could cut my self when trying to cut the apple i could be careful when cutting the apple

Safety Or Environmental Concerns
I could cut my self when trying to cut the apple.

Experimental Design
(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

 * Item || Number needed || Where I will get this || Cost ||
 * Tupperware || 1 || house || n/a ||
 * ziplock bag || 1 || house || n/a ||
 * fridge || 1 || house || n/a ||
 * apple || 1 || house || n/a ||
 * knife || 1 || house || n/a ||

Detailed Procedure
1.Cut apple into 3 equal pieces 2.Get a Tupperware container, Zip block bag,and a fridge 3.Then put the apple in the fridge and in a Tupperware container and also in the ziplock bag 4.check on them every 10 minutes for a hour 5.Measure brownness with 1 by 1 squares drawn on to a ziplock bag 6.record data

Time Line
3/1 experiment done 3/7 analysis done 3/15 discussions due 3/22 poster due 3/29 science fair!

Numbers indicate browning per square centimeter

Results
What I found out after doing my experiment is that brownness occurs slower when in a Tupperware container then in a ziplock bag or in a tupperware container

Conclusion
After doing my experiment i conclude that browning of a apple occurs slower in the Tupperware container then it does in the fridge container or ziplock bag. Limiting exposure to oxygen keep an apple from browning.

Discussion
To do my experiment i drew a grid of 1 by 1 centimeter squares and cut a apple int three pieces and put one in the fridge, one in a ziplock bag, and one in a Tupperware container. I then checked it every ten minutes for forty minutes. I appears that keeping air away from from the apple helps it from not browning. When a apple turns brown its because oxygen is exposed to it. When it is in a Tupperware container it keeps the oxygen from being exposed to the apple.

Benefit to Community and/or Science
The benefit to the community or science is that people will want to know why a apple turns brown so they can do stuff to prevent the apple from turning brown. So they dont waste money.

Background Research
After I conducted my experiment I did some background research. During my searches, I learned that the browning of apples occurs when the fruit is cut or bruised, and the damaged tissue is exposed to oxygen. That is also what happens when you drop a apple its tissue breaks and is exposed to oxygen.

Fun Facts on Apples
The largest apple ever picked weighed three pounds, two ounces.

One medium apple contains about 80 calories.

Red Delicious is the most popular and most-produced apple in the United States. Golden Delicious is the second most popular.

The only apple native to North America is the crabapple.

Abstract
For my experiment what i was trying to figure out was which one browned faster a Apple in the fridge, a apple in a ziplock bag, or a apple in a Tupperware container. What I did was cut a apple into three pieces and put one in the fridge, one in a ziplock bag and one in a Tupperware container. Then i made a 1 by 1 cm graph and after 10 minutes i would check the apples and put the 1 by 1 cm graph over the apples and see how much squares were filled up with brown. I did this for 40 minutes.
