Use appliance monitors to understand the energy use of individual appliances

10 Investigating energy usage KS1, KS2, KS3

What you did

We tested how much energy various appliances use around the school. We found that  the hot water boiler and water cooler in the staff room use a lot of electricity, and will use the appliance monitors over a longer period (a week or two) to calculate up how much these appliances use over the year.  The fridges and freezers in the school kitchens also appear to use quite a lot of energy compared to modern energy efficient fridges and freezers, so we will investigate further how much we think these use over the year. 

Activity description

Appliance monitors let you see the energy that an appliance is using as well as adding up the energy that the appliance uses over a period of time. You can also use the appliance monitor to see how much it has cost to operate the appliance for a certain amount of time. Children will understand how much energy an appliance use and can develop an understanding of what this means in terms of real world cost.
