Effect of temperature on glow sticks
The hypothesis that light from a glow stick will extinguish faster at higher temperatures is correct.
Glow sticks are very popular with children at all sorts of festive events and parties. Spectators carry them duringparades to add to the festive atmosphere. However, the plastic tubes/containers need to be disposed properly after use because the chemicals within the glow sticks are toxic. Contact with skin must be avoided.
Try to repeat the science fair project using different colored glow sticks and compare their glow time.
The experiment can also be done to compare results produced by different sized and shapes of glow sticks.
