Which is the variable and which is the control??? PLZ HELP DO NOT SKIP IMPORTANT DUE TOMORROW?

i am doing a PROJECT ON POTATOES AND i want to know which is the variable and which is the control. there are 9 potatoes 3 i put in the microwave, 3 i put in the oven, and the last 3 i put on the stove in 1000 mL of water.Which is the variable and which is the control??? PLZ HELP DO NOT SKIP IMPORTANT DUE TOMORROW?
variable is what ur changing to see how it affects the control


in ur case it should be the method of heating


the control is what stays the same, so the potato





determining the variable and the control depends on what ur asking in the experiment....if u r asking what effect does heat have on the potato then its likely that the control is the potato (it stays the same) and the variable (thing that u are varying) is the method of heatingWhich is the variable and which is the control??? PLZ HELP DO NOT SKIP IMPORTANT DUE TOMORROW?
the variable is the heat you place on the potatoes or where you place them


the control is the number of potatoes
