Cross Cutting Concepts
Energy and Matter Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system. Systems and Systems Models Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.

Understand and apply the principle of conservation of energy to determine the total mechanical energy stored in a closed system and mathematically show that the total mechanical energy of the system remains constant as long as no dissipative (i.e. non-conservative) forces are present.

(Law of conservation of energy) (7.PS.8) Construct a device that uses one or more of Newton’s laws of motion. Explain how motion, acceleration, force, and mass are affecting the device. (7.PS.7) Describe how potential and kinetic energy can be transferred from one form to another. (6.PS.3) Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents. (4.PS.5) Describe and investigate the different ways in which energy can be generated and/or converted from one form of energy to another form of energy.
