Science Buddies: "Ask an Expert"

Okay, first of all, how do glow sticks work? What affects the chemical reaction in glow sticks and what happens when the matter in glow sticks is heated or cooled?
Second, why do the glow sticks glow longer when they're cooled, and brighter when they are heated?

Thanks!!
