Investigating Energy Conservation
Energy ecoSTEM Kit Materials Used: Kill-A-Watt EZ Meters, Infrared Thermometers & Ice Cube Trays
ENGAGE - Students Observe This Phenomenon
EXPLORE a Kit-Supported Learning Experience
Students will work in teams of four using KillAWatt EZ meters to test various electronics, appliances, and devices and determine how much energy they draw. Students will search for the worst “Energy Vampires” which use power even when Off or in Standby mode. They may also calculate cost savings of electricity once inefficient devices are removed.
Students should be able to make a claim about one electrical appliance or device that would make the most difference to disconnect from power when not in use, defend the claim by providing evidence (data), and connect the data to the claim with reasoning.
This explainer video on The Surprising Places We Waste Energy will help re-teach the core ideas about energy conservation and inspire students to consider ways they can reduce energy use. Infrared thermometers can be used to locate areas of a building lacking insulation.
Students expand their energy audit to include efficient lighting, lights off practices, vampire appliances, etc. and develop a school conservation plan; compare before/after bills.
