How do glow sticks work science project?
The Science Behind the Fun No light can be released until the chemicals are mixed together. When you mix the chemicals together by cracking the glow stick, they react to make new chemicals and release excess energy in the form of light, transforming chemical energy into light energy.
What makes a glow stick glow brighter?
The stick in the warm water glows more brightly than the stick in the cold water. The reaction that causes the stick to glow is happening much faster in the hot water, which makes the glow appear brighter. The cold water is slowing down the reaction. This is the reason people sometimes put glow sticks in the freezer.
What is the independent variable in the glow stick experiment?
For this science fair project, the independent variable is the temperature of the water in the beaker, i.e. 5°C, 15°C, 25°C, 35°C and 45°C. The dependent variable is the average length of time the sticks will glow. This is determined by using a stopwatch to measure the time.
What happens if you put glow sticks in water?
While submersing a light stick in a container of water – like a milk jug, glass bottle or fish bowl – will create a cool, decorative effect, it does not amplify the light. Colder water will have the opposite effect – the reaction slows, making the stick appear less bright but for a longer period of time.

What factors affect glow stick reaction?
Glow Sticks and the Rate of Chemical Reaction Several factors affect the rate of a chemical reaction, including temperature, concentration of reactants, and the presence of other chemicals.
Why does temperature affect glow sticks?
Temperature directly affects glow chemical products, whatever form they are in. The reason an activated glow stick lasts longer in colder temperatures is because the colder temperatures slow down the chemical reaction. By placing a glow stick in the freezer you freeze the chemicals, slowing the reaction right down.
Can u put glowsticks in a pool?
All traditional glow sticks are waterproof, most float and are perfectly safe for use in a pool. We recommend sticking with classic glow sticks when it comes to the pool party.) Some common Glow Sticks for pool use include 4 Inch Glow Sticks or 6 Inch Glow Sticks, Glow Bracelets and Glow Necklaces!
Is Luminol used in glow sticks?
Glow Stick Chemical Reaction There are several chemiluminescent chemical reactions that may be used to produce light in glow sticks, but the luminol and oxalate reactions are commonly used.
