Science+Fair+Notes+MJ

My science fair project is about how long it takes apples to rot.

My hypothesis: I think that it will take 6 to 7 days for the apples to rot, sitting out not in the fridge, and I will use red apples for my experiment.

 * if the apples are left in the fridge they will last longer than if they are left out
 * If they are left in the fridge they can last up to 1 week
 * if the apples are bitten out of or sliced they will only last 3 to 4 hours
 * how long it takes to rot all depends on the type of apple it is
 * it also depends on where you are storing the apples
 * in room temperature it would take 4 to 6 days for them to rot

 * apples have many different micro-organisms and bacteria which makes it rot faster
 * but when left in the fridge the cool air slows down the process of these bacteria and micro-organisms in the apple
 * apples would start to decay after a long time siting out in room temperature
 * when apples sit out for a long time all of the moisture gets pulled out of it

 * that creates mold which makes the apple rot quicker
 * bacteria starts to grow when the apple is sitting in a warm spot like the kitchen
 * also apples are the fruit with the most bacteria and micro- organisms that make it rot faster than other fruits
 * different pathogens have different effects on many different kinds of apples
 * big factors of the rotting process are humidity,light,and heat- these are all environmental factors

 * many different kinds of bacteria make more every 20 minutes under certain conditions
 * bacteria grows in food that is not protected by preservatives
 * bacteria, yeasts, and molds all cause spoiling in the food
 * canning or storing can preserve these items by many days maybe even weeks
 * high temperatures usually kills most bacteria
 * by sealing in airtight bags really helps with the process of rotting
 * heating also kills bacterial
