Energy leaks 2. Appliances use electricity 3. The traffic report 4. Appliances use electricity Procedure Ask students how the electric company knows how much to charge for electricity people use. The dials in the meter spin fast when electricity use is high, slowly when use is low.
Students can try to find the electric meters in their houses or apartments.
Meters are sometimes inaccessible in multiple unit housing. Ask the school custodian if students may observe the school's electric meter. If possible, have students record the row of numbers on one day and then on the next. By subtracting the first number from the second, they can determine the amount of electricity the school used in one day. Ask students to make a list of ways that the school could use less energy.
