In this demonstration, students observe what happens to activated glow sticks when they are submerged in water at three different temperatures: cold, room temperature, and hot. Students will use these observations to discuss the type of light emission associated with glow sticks. Alternatively, the activity could be performed, with the appropriate safety considerations, by students.
