If you have access to the electric meter in your home or building, you can read the meter to see how much electricity is being used each day. (Most meters have 5 dials.)
Steps:
- Record the readings at a specific time of day by recording the numbers displayed on the dials.
- The next day, at the same time, record the numbers displayed on the dials.
- Subtract yesterday's reading from today's reading and you can get an idea of how much energy (kilowatt hours) is used in one day.
- Have the children continue with their readings for a few days. Then they can put the data in a chart or create a graph of the data.
- Younger students can calculate the amount of electricity used in 3 days or 7 days, etc. Older students can also find the average amount of electricity used per day.
