Middle School Home Energy Audit
Information for Lighting Dilemma Experiment
|NTEP Home||Project Homepage||Teacher Homepage||Student Homepage|
This laboratory activity is designed to provide students with a simple, yet effective, introduction to power use. The experiment is centered on the comparison of different power light bulbs and different types of light bulbs (incandescent, fluorescent, compact fluorescent, halogen, etc.) with respect to the amount of light produced compared to the power used by each. This approach not only permits the discussion of basic concepts related to energy, work, and power, but also allows the introduction of efficiency as a concept. In the larger scope of this site as a whole, this specifically allows connections to the home energy audit and proposals for energy-saving measures.
From a more global perspective, this hands-on activity provides a gateway to student designed experimentation. Students should be encouraged to propose questions or dilemmas of their own and, subsequently, design experiments to investigate and possibly solve their own issues.
SHOCK HAZARD!!! MAKE CERTAIN BEYOND ALL DOUBT THAT LIGHT SOCKETS, WIRING, AND BULBS ARE SAFE!!!
INSTRUCT STUDENTS ON THE PROPER AND SAFE WAYS OF HANDLING THE MATERIALS THEY WILL BE USING.
SUPERVISE STUDENTS AT ALL TIMES DURING THIS ACTIVITY.
