The purpose of the experiment was to find out which fruit: banana, apple, orange, kiwi, strawberry, pear would rot the fastest in both room temperature and refrigerator. We found out that the banana rots the fastest in both room temperature and refrigerator and the apple rots the slowest in room temperature and refrigerator. This means that the bananas don't last really long before they rot and the apple lasts along time before it rots. After 30 days the banana rotted the fastest in both room temperature and refrigerator and strawberry was a close second. Pear rotted the fifth in refrigerator and third in the room temperature. Orange was fourth in room temperature and third in refrigerator. Kiwi was fourth in refrigerator and fifth in room temperature. Last the apple rotted last in both room temperature and refrigerator. Our data shows that the banana rots the fastest in both with the strawberry in close second for both. The pear in third for room temperature and the orange third for refrigerator. The orange fourth in room temperature and kiwi for refrigerator and the kiwi fifth in roon temperature and pear for refrigerator and for last place fr both was the apple.
We hypothesised that the banana would rot the fastest in both room temperature and refridgerator. Also we said the fruit that would rot the slowest in room temperature was the strawberry and the slowest in the refridgerator was the strawberry. We got 75 percent of our hypothoesis correct. This narrows between the strawberry and banana for fastest rotting fruit and the apple and kiwi for the slowest rotting fruit. We found out the climates of the fruit from http://www.crfg.org/pubs/ff/banana.html, http://answers.yahoo.com/question/index?qid=20080725110855AA7mhs1, and http://www.chacha.com/question/what-climate-do-strawberries-grow-in and we thought that the climate the fruit was grow affected the results of the experiment.
The investigation taught us that bananas don't last very long but they do last longer in refrigerator. Pears last longer in refrigerator then in room temperature. The strawberry didn't last very long in both environment either but it lasted longer than the banana. the orange lasted the long but in the inside it was rotten in both environment. The kiwi lasted a long time in both environment but after awhile in the room temperature kiwi got squishy. the apple lasted the longest and inside it was not rotten either. This is important because it shows wear a better. It makes sense because we saw it with our own eyes and because we knew about the banana and the apple but the strawberry now we understand that it rots really fast figure out why it does this in room temperature and slow in refrigerator so it makes sense but it is confusing to understand why it does this but we now know what happens.
The outcome of the experiment is important to us because we are both bakers and use these ingredients so we don't want to waste so we need to know a place where the fruit will last the longest so it doesn't spoil. This information will help us to keep the fruit the the best controlled environment as possible so we don't have to waste. This benefits us from wasting money on fruit that hasn't even seen used.
This investigation has caused us to think of other experiments that we can do like which rots the fastest and slowest in heat. Also how hard fruit gets after being in a refridgerator for along time. And last which fruit gets squishy after being in heat for along period of time.
Type of Data: qualitative data
Graph: We had table graph is used to see the progress of the rotting of the fruit each day.
Analysis:
We don't think a graph is needed because a bar graph is needed because we used words to explain our rotting fruit progress and it doens't make a lot of sense when using graphs to explain to progress of the fruit.
Graph: We noticed the the orange, apple, and kiwi were the slowest fruits that rotted in both room temperature and refrigerator they both had about the same smell, color, and texture were about the same at the start it is different from the banana and the strawberry and pear( in room temperature for pear only.)
Graph: We noticed the strawberry and the banana rotted a lot faster than the orange, apple, and kiwi. The banana and strawberry were very brown and black at the final day. The banana was very squishy and the strawberry was very hard. They both smelled really bad also they were different colors before the first day, and felt a lot different.
Graph: We noticed that the pear rotted 3rd in the room temperature and 4th in refrigerator so it was different for both of the areas. It was both in the middle of the pack for both environments but it rotted faster in room temperature then refrigerator.
Data Table: We see that the banana rotted the fastest in both room temperature and refrigerator than all the other five fruits. It was between the banana and the strawberry for first place.
Data Table: We see that the strawberry rotted the 2nd fastest for both the environments than all of the other five fruits. It was a close second between the banana and the strawberry.
Data Table: We see that the pear was in 3rd for being the fastest in room temperature and 4th in the refrigerator out of the five other fruits. It was a solid third for the room temperature but for the refrigerator it was like a three way tie.
Data Table: We see that the apple was the slowest for both room temperature and refrigerator out of the five fruits. It was close between the kiwi in both environments but apple took the the slowest rotting fruit.
Data Table: We see that the kiwi came in fifth for both room temperature and refrigerator out of the five fruits. It was a close second between the apple and kiwi for the slowest fruit.
Data Table: We see that the orange came in fourth for room temperature and third for refrigerator out of the five fruits. It was close to the pear for the refrigerator but in room temperature orange was much more normal then the pear.
Overall: We noticed that the banana rotted the fastest for both environments and most fruits were either a close to the first day and didn't make a lot of progress or a close second with the banana. This means that the banana doesn't last in both environments very long and must fruits last pretty long in both environments and some are a close second to the banana.
We controlled the controlled variables because we kept the temperature in both room temperature and and refrigerator the same temperature the whole experiment so it wouldn't have a humorous change in temperature that could have changed the results. Due to plans we tested different times each day but we do not think that effected our project. because they were still examined in the same day.
Procedure- We get 2 fruits of each kind the banana, pears, strawberries, apples, kiwi, and oranges. One for the refrigerator and one for room temperature.
We will get the fruits and exam everyday for 4 weeks.
And we will exam the fruits each day in the morning and after school everyday for 4 weeks.
We will take pictures of each fruit each week for four weeks.
And conduct which rots over time of 4 weeks we will examine the texture, the color, and spots or other.

Hypothesis
Prior Knowledge: (R-A) We believe that the fruit that will rot the fastest in room temperature is the banana (S) because we know the banana is grown in hot climates so it is not used to the room temperature climates which most of the other fruits we are doing are grow in the room temperature climates so that will make the fruit rot since it is going to be in a different climate change.(R-A) We believe that the fruit that will rot the fastest in the refrigerator is the banana (S) because since it is grown in hot climates and the refrigerator is a chilly climate this food is the farthest away from the climate that it is grown in. With the other fruits it is near the same climate but it is closer to the refrigerator climate than the climate from the banana to the refrigerator.(R-A) We think that the fruit that will rot the slowest in room temperature is strawberries (S) because since strawberries are the closest temperature to room temperature (60 to 70 degrees) it would be the most comfortable with the climate that it is in. With the other fruits they just either to high from the room temperature or to low of the room temperature so that makes the strawberries the best choice. (R-A) We think the fruit that will rot the slowest in the refrigerator is apples (S) because apples are grown in a cold climate (around 30 degrees) and the refrigerator is temperature is around 20 to 30 degrees so it is used to this weather. With the other fruits they are grown it warmer climates than 30 degrees so they are not used to this climate so it will make them rot faster and this makes the apple the best choice. (E) Based on our experience with fruits we think that the banana will rot the fastest in both room temperature and refrigerator and the fruit that rots the slowest in room temperature is the strawberry and the fruit the rots the slowest in the refrigerator is the apple.
Resources: The internet agrees the banana rots the fastest in both the refrigerator and room temperature because of its way of texture and how it is a very soft fruit. So it says that since its texture it doesn't work well with the air so it makes the fruit rot and causes the fruit to rot and gets all kinds of dots. And because of it climate that it is grown in and since room temperature is different it affects how it adapted to warm weather and now it has to suffer in colder weather. An apple rots the slowest because its fungus and bacteria and it takes a short time to where in. And it use to the cold temperature so it doesn't have adapt as much. The strawberry rots the slowest in the refrigerator because of since it is use to the cold climate of the refrigerator it will be easier for the strawberry to adapt. The Resource 1:http://www.crfg.org/pubs/ff/banana.html we all only uses adaptation paragraph for both bananas. Resource 2:http://answers.yahoo.com/question/index?qid=20080725110855AA7mhs1 for apple. Resource 3:http://www.chacha.com/question/what-climate-do-strawberries-grow-in for the strawberry.
Date Due: 2/2/11
Purpose: To find out which fruit rots the fastest versus which fruit rots the slowest.
Data&Methods: In order to get our answer of this purpose 6 fruits will be left out in room temperature for 4 weeks. The same 6 types of fruits will be left in a refrigerator for 4 weeks. Each day the fruit will be analyzed to find out which fruits are rotten and which fruits aren't. The data will be collected and analyzed.
Interest: We want to know because it seems like an interesting topic to find out and seems really fun to do. And since we are both are fans of baking and fruit has to do with baking it can help us with our recipes.

Brielle if we are working on the science fair on thursday 5-12-11 i finished both the pink and orange sections and there are no more parts of the science fair to do so make the page really colorful and cool ok but don't change the righting. But read over it so you understand what i wrote so only the orange and pink sections.
