Activity: Comparing the Energy-related Properties of Incandescent and CFL Bulbs

The NEED Project has an activity titled Facts of Light that has students compare the energy-related properties of different types of light bulbs that have equivalent light outputs.  The goals of the activity are:

– To compare the heat output of incandescent and compact fluorescent bulbs.

– To compare the light output of incandescent and compact fluorescent bulbs.

– To compare the energy consumption of incandescent and compact fluorescent bulbs.

– To develop an awareness and understanding of life cycle cost analysis.

Facts of Light is available for students in grades 6-8 in NEED’s curriculum Monitoring and Mentoring Teacher Guide and Student Guide

and for students in grades 9-12 in NEED’s curriculum Learning and Conserving Teacher Guide and Student Guide.

Asking students to conduct these same activities with an equivalent light emitting diodes (LED) bulb is a possible extension.  At a minimum students could do a life cycle cost analysis for LED bulbs.
