Glow Sticks: Temperature Effects

Glow Sticks: Temperature Effects | Science Fair Projects | STEM Projects
We'll investigate how the temperature of water affects the length of time a glow stick glows. We'll use five beakers of water at different temperatures and measure the time it takes for the glow sticks to stop glowing.


The hypothesis is that the light from a glow stick will extinguish more quickly at higher temperatures.

Method & Materials

You will label five beakers with different temperatures, add water and glow sticks to each beaker, and measure the time it takes for the glow sticks to stop glowing.
You will need five beakers, 1500ml of distilled water, a measurement cylinder, 25 glow sticks, a stopwatch, two hot plates, five thermometers, and a bag of ice.


The results showed that the glow sticks in the warmer waters glowed brighter but they also extinguished the fastest. The glow sticks in cold water were dimmer but continued to produce light the longest.

Why do this project?

This science project is interesting because it shows how temperature can affect the light from glow sticks.

Also Consider

Consider repeating the experiment using different colored glow sticks and compare their glow time. Also, try the experiment with different sized and shapes of glow sticks.
