How much electricity do we use?

In this quest each student will be accessing the internet to gather information and collect data from a table to generate a bar graph and a pie chart of the amount of electricity used by residents of the U.S. You will have to measure the data and calculate the numbers to draw a conclusion to the amount of electricity used per state. Then you will choose five devices you use in your home and measure the amount of hours and the cost of electricity used by determining which device uses the most and least electricity.
