Conclusion The hypothesis for the glow sticks in different temperature experiment was accepted. The data used for the experiment that supports my hypothesis was that the glow stick in the glass cup filled with two hundred thirty-five milliliters of filtered cold water illuminated the longest. This glow stick in the cold water lasted on average of all three trials for ten hours and thirty-six minutes. The cold glow stick lasted three hundred and sixty-six more minutes compared to the lowest lasting time of which the hot water glow stick lasted. On average the hot water lasted four hours and nineteen minutes, and the room temperature glow stick lasted eight hours and fifty-seven minutes. I think the cold water lasted the longest because molecules move slow in cold water, causing it to slow the reaction down which made it last longer. In this experiment the outside factor might have been the color of the glow sticks which was pink. This may have also had an effect of how long …show more content…

One problem I faced was when the cheap thermometers stopped working in trial one, but luckily there were backups. While half way through the experiment, I came up with a better and shorter idea of a project. Instead of having to see how long the glow stick last in different temperatures I could see which glow stick glows the brightest after a short period of time. After an hour or so goes by I could look at each glow stick in the different temperatures individually and rank one out of ten how bright the glow stick is. However, seeing glow sticks in different temperatures and which glow stick last the longest is still a very useful experiment. People can now improve this product just by looking at the results of this project. Perhaps if this fact of glow sticks glowing longer in a colder atmosphere can be spread around the world, people can use it for the benefit of a long lasting glow
