Reviewer Comments:

In this resource, students measure the light output and temperature (as a measure of heat output) for three types of light bulbs to identify why some light bulbs are more efficient (more light with less energy) than others. This engaging activity is detailed and clear, and allows for the collection and analysis of real data. A subsequent activity asks students to take a critical look at the lighting in their own homes, and to calculate the energy, and ultimately the amount of money, they could save by switching to CFLs. Although the ideas are simple enough to be adapted to younger grades, the math involved is complex enough to make this activity more suitable for late middle or early high school. The handouts are student-facing and there are no separate teacher prep materials, although an instructor can easily prepare the activity from reading just these student handouts.
