How does temperature affect the glow of a glow stick? My hypothesis is that if we place a glow stick in a lower temp, then the glow will last longer. To test this hypothesis we got three cups of water, one hot, one room temperature and one cold. We then broke and placed 3 glowstick in the cups. We set a timer for 2 minutes and let the glowsticks sit in the water, when the timer went off we took the glowstick out. We then laid them on a black piece of construction paper and put a ruler on the side of the stick. We used Hannah’s hand to measure when the glow ended. Then we put the glow sticks back in the water for 2 minute intervals 4 more time, taking them out and measuring their glow when the timer would go off. This experiment showed that the glowstick placed in the hot waters glow was the longest, the stick placed in the room temp had the second longest glow and the stick placed in the cold water had the shortest…show more content… This data shows that if a glow stick is placed in hot water the distance of its glow will be longer than a the glow of a glow stick placed in room temp and cold water. It also shows that the distance of the glow will go down the longer it is put in the water. The distance of the glow from the glow stick out in the hot water is the longest out of all three. Then there is the room temp water and lastly the cold. This provides evidence for the claim as the glow stick placed in the hottest water had the longest glow, the glow stick placed in the middle temperature water had the second longest glow and the stick placed in the coldest water had the shortest glow. The data I have collected proves my claim because the glow stick that was soaked in the hot water had a longer glow distance than the glow sticks placed in the room temperature and cold
