• Hypothesis: I think that banana will rot the fastest because when it is left outside of its skin it is open to carbon dioxide which when food is left out it can be contaminated by flies and by diseases that are in the air from sick people or even from small bugs that are out and around us. The banana will then become black ,really soft , moldy and even can have flies in/ hovering/outside of it.The reason that i think it will rot first is because bananas are really soft and has things in it which can rot fast and can not preserve it.
