7.Place on a paper towel and rate them in order from brightest to darkest. 3=brightest 1=darkest.8.Record data.When we changed and revised our lab, we let the glow sticks stay in the water for an extra few minutes so that the chemicals inside the glow sticks could be fully affected by the temperatures.Results and Data Table: Glow Stick Water TemperaturesRating (3-1Hot Water3Room Temperature Water2Ice Water1
Dow 4The hot water glow stickwas noticeable brightest,and the roomtemperature water glowstick was slightly brighterthan the cold water glowstick.Our hypothesis thatstated that the cold glowstick would be brightestwas incorrect. These charts also applyto our second lab wherewe tested the glow sticksfor more time.Analyzed Results:Our results were that the glow stick that was in hot water was much brighter than the other two glow sticks and the room temperature glow stick was brighter than the cold water glow stick. This must mean that the heat affects the chemicals in the glow stick and makes it work better.I think that our experiment was flawed because we could have gotten different results if we left the glow sticks in the water for a different amount of time.To improve the lab, we put the glow sticks in their water longer so that we could see wether or not the brightness of the glowsticks was effected by the amount of time left in the water. The second time we did the lab, the glow sticks were left in the water for ten minutes and then their brightness was compared and rated again, there was no change in brightness compared to the data collected from the first lab. If I did a third experiment,
