Light+Intensity+vs+Distance

On this page we're placing the results of our study of how light intensity varies with distance from the light source. The 12th grade PreCalc class is conducting this investigation.

We are using Vernier Lab Pros and Logger Pro software. Vernier makes a light sensor specifically for use with their Lab Pro, but we have some home made light sensors we'd like to be able to use. The question is whether or not they make an acceptable substitute for the Vernier sensor.
