My 5th grader has been doing the project listed on your Science Buddies site. He selected the project on his own. He constructed the device, took the measurements, but now we're trying to analyze the data and come up with a conclusion and we're all at a loss. I have no idea what this experiment is supposed to be proving - we've read through the introductory materials at least ten times, he has no hypothesis, no question to answer, and even though he now has the information about the light emitted from the various colored LED lights, we don't know what to do with it.

We've done multiple Internet searches trying to find the answers, but things are either written in broken English or so far above our heads that we don't know what they're trying to say.

It's obvious that as the flashlight reaches its thermal equilibrium that the power of the light starts to fade. Why? What is this showing that a 10-year-old can understand?

We really need some help - this project is due in a couple of days.

Thank you!
