Survey
At first, you have to delimit the area where you are going to take up the challenge.
This area can be your classroom if it is properly equipped, a part of the school or a room with numerous electric devices.
The case of the computer is particularly interesting. Be sure that there is at least one computer in your inquiry area.
Use a Wattmeter and inquiry forms 
.
[ Proceeding ]
Proceeding :
- work in small groups of 2 or 3 students ;
- use a wattmeter and inquiry forms ;
- assign to each group a definite area to explore ;
- make a list of electric devices in the observed area ;
- measure the power of these electric devices in their different states and note the results on the form ;
- estimate the use duration for each state and note it on the form ;
- calculate the electric consumption for each state ;
- set up the results of the inquiry in the different groups and pool them. See the rubric « Inquiry results » ;
- try to find solutions collectively in order to save energy and mostly to eliminate the hidden consumption. See the rubric « Action Plan ».
