My experiment is to see which slice of apple will stay the freshest in aluminum foil, plastic wrap, or a plastic bag in the fridge.I don't really get how to get the independent, dependent, and control variablesI know the definitions but i don't know how to figure them out in an experimentPlease help, my variables are due monday, and i'm not asking for the answers so i can directly paste them onto my paperI want to know the answers so the next time i do an experiment i'll know what to do.
It would decrease insulationFiberglass insulation is engineered with air pockets for optimum heat retention If it WAS better to pack it in, manufacturers would sell a higher density product and charge more.
Materials like glass wool rely on the trapped air spaces to provide the insulating propertiesIf the glass wool is compressed or packed the size of the air spaces are reduced or eliminatedThis reduces the insulating capacity of the material because the amount of deal air is reduced.
your independent variable is: the things the apple was enclosed in (the foil,plastic rap,and plastic bag your dependent variable is: how fresh the apple stays in each independent variable your controlled variable is : the fridges tempture the size of the slice of apple
