Compact Fluorescent Light Bulbs - Cost-Benefit Analysis

In this activity, students collect data and analyze the cost of using energy in their homes and investigate one method (switching to compact fluorescent light bulbs) of reducing energy use. This activity provides educators and students with the means to connect 'energy use consequences' and 'climate change causes.' Through examining home energy use and calculating both pollution caused by the generation of electricity and potential savings, students can internalize these issues and share information with their families.

Teaching Tips

Educators will need to assign first two columns of audit worksheet as homework prior to starting this lesson.

Activity could be a great way to involve parents in science learning at home.

Students will need some help to go through the long series of calculations.

Educators should stress that the personal change in energy has to go beyond changing light bulbs, but it is a good start.
