My science fair topic is “How Long Does it Take for Apples to Rot?” My hypothesis is, it will take 6 to 7 days to rot. I will do 3 trials of this experiment. The procedures that I will follow are, first I will put out 1 red apple out in room temperature and let it sit out. I will take notes and take pictures of it everyday that its sit out. The purpose of this experiment is to see how molds and funguses make fruits rot when they sit out for an extended period of time. Next, I will place an apple in the refrigerator and check on it each day and record my findings. Last I will compare the apple in the refrigerator with the one sitting out in room temperature and see the differences between the two.

In my research I learned that on all fruits and vegetables there is bacteria that make them rot faster. (Science for Kids ) The temperature is a big part, for example, if an apple is sitting in a warm spot the bacteria will grow faster then if it was sitting in room temperature or cool air. ( Ask.com) I also learned that when a fruit or vegetable is stored in the refrigerator it will stay fresh for up to 1 week because of the low temperature. This slows down the rotting process. (Moyer Richard) If the apples are bitten out of or sliced, it will only take a few hours for them to go bad. (ask.com) In my project I will be using red apples. In this experiment it all depends on the kind of apples you are using.

Also in my research, I learned that when apples sit out, all of the moisture is pulled out of it. (Science for Kids) Another factor in the rotting process are environmental factors, such as heat, humidity, and light. These factors can affect the apples when they are sitting out. Apples are the fruit with the most bacteria. Heating or cooling can stop the bacteria and molds from making the apple rot. Many different kinds of bacteria replicate every 20 minutes under certain conditions. All bacteria grow in food that is not protected by preservatives to make it stay fresh longer. Canning or storing apples in air-tight bags significantly helps them to stay fresh for a few weeks. (Moyer, Richard)

In my experiment I wanted to see how many days in total it takes for the 2 apples to turn completely brown and have no moisture on them at all. I will test how they look after one day, two days, and then so on. I will also test how long it takes for bacteria to grow. Additionally I want to see how dry the apples will look like by the end of the experiment. This will most likely prove that the refrigerator keeps fruits fresh longer and room air does not.
