• .Describe all of the energy types and transformations that occur while you do the event. For example, if you were talking about driving, you would need to connect the burning of gasoline (chemical energy) and its conversion to the motion of the car (kinetic energy).
• .Estimate efficiencies of the different transformations. For at least one, try to find or calculate numbers.
• .Be clear about the system you choose, then describe the kinds of energy transfers into and out of the system that occur. Where does the energy come from, where does it go?
