Learning Goal(s):

Students will be able to:
• Explain the difference between power and energy
• Proficiently use a “Kill-A-Watt” meter to determine the power and total energy usage
of everyday devices
• Compare the total energy used by common household devices
• Brainstorm different ways we can conserve electrical energy

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)
