Introduction:
Consumers are naturally concerned about the total cost of all the energy they consume. The cost charged by the electrical utility (PECO in our area) can be calculated by multiplying the power rating of the device and its time of use. Even a low level of power consumption will add up to a large utility bill, if the device is operating continuously!

Activity:

 * In today's lesson, you will operate a simulation that allows you to see how quickly appliances consume energy. In this simulation, you will have three different outlets for appliances, and you can choose which appliances to plug in. The time frame is speeded up to allow you to see how quickly each appliance consumes energy.

 * The accompanying Quia quiz will test your understanding of the simulation! You will need to use the simulation as you answer the questions, and you are welcome to work with a neighboring student on the quiz.
