Students will learn the difference between energy and power. They will then use this new understanding to compare the energy and power difference of light bulbs (incandescent, halogen, fluorescent, and LED) using a tool called a “Kill-A-Watt” meter. Students will also perform simple calculations to find the total amount of energy used if the power usage and number of hours a device is used is known. This lesson is related to Debbie Frankel’s lesson, called “Home Energy Consumption”. This is suitable as a stand-alone lesson.
