Investigating the Relationship Between Light Intensity and Distance

Maybe we should use the photoresistor sensor? https://loft.io/discourse/attachments/project/project/272/Photoresistor%20Sensor.jpg

No, that is still using a photocell. Besides, I think we need a digital display on the meter, so we need a different output. Let's try this one: https://loft.io/discourse/attachments/project/project/272/Digital%20Light%20Intensity%20Sensor.jpg
There are photocells in the kit, but it says here they are really inaccurate: http://en.wikipedia.org/wiki/Photoresistor
Our goal is to find out what happens to the intensity of light as distance changes, so we are going to need to figure out which sensor works best for this. Any ideas?
