Light Stick Chemistry

In groups of three with the lights off and the shades drawn, investigators place inactivated light sticks, in three beakers: one filled with ice water, another with lukewarm water, and the other with room temperature water. They wait several minutes and then activate the sticks, comparing their brightness. Using a digital camera, they continue to make observations over 15-minute intervals. This is a terrific experiment to do with beginning chemists around Halloween, when light sticks are easily available.
