14 ) Use models to construct an explanation of how a system of objects may contain varying types and amounts of potential energy (e.g., observing the movement of a roller coaster cart at various inclines, changing the tension in a rubber band, varying the number of batteries connected in a series, observing a balloon with static electrical charge being brought closer to a classmate's hair).

15 ) Analyze and interpret data from experiments to determine how various
factors affect energy transfer as measured by temperature (e.g., comparing final
water temperatures after different masses of ice melt in the same volume of
water with the same initial temperature, observing the temperature change of
samples of different materials with the same mass and the same material with
different masses when adding a specific amount of energy).
