The independent variable in this investigation is the type of cup being used. Maria is using three different types of cups - paper, plastic, and glass - and she wants to record their different temperatures when pouring the same amount of water (50 ml) into each cup. By changing the type of cup, Maria is testing to see if the material of a cup affects the temperature reading after the same amount of time has passed.
