Energy Change in Components of a System
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

Macroscopic Energy Due to Particle Position and Motion
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects).

Energy Conversion Device Design
Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy. 

The Second Law of Thermodynamics
Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system second law of thermodynamics).

Energy Change Due to Interacting Fields
Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
