 * THE STUDY OF THE AMOUNT OF LIGHT A GLOW STICK EMITS **

Caroline B 2011-2012

The purpose of this study was to show which color glow stick glows the brightest, and which color glow stick is longer-lasting. Glow sticks glow due to a chemical reaction. This chemical reaction is called chemiluminescence, or chemical light. One of each color glow stick was taken and the lux was found to see which gave off the most light, least light etc… The green glow stick turned out to be the brightest while the pink glow stick is the longest lasting.
 * ABSTRACT **

In conclusion, it has been found that the green glow stick is the brightest but falls in third for longest lasting (light wise not time wise). The yellow glow stick falls in second for brightness but last for longest lasting. The orange glow stick falls in third for brightness but in second for longest lasting. For brightness, the pink glow stick is in last with its highest lux being 6.6. The pink glow stick is also the longest lasting glow stick. This experiment could be important to scuba divers when they are looking for a long lasting yet bright glow stick when they go diving in deep dark waters. The hypothesis was that the yellow glow stick would be the brightest due to the fact that it is the brightest out of the four colors (green, yellow, pink, orange). This hypothesis was proven wrong by the fact that green ended up being the brightest glow stick. For future follow-up experiments, it would be fun to figure out how much light other color glow sticks give off and to see if more glow sticks combined give off more light.
