What the Correlation between glow sticks, temperature changes and the light emitted. Purpose The experiment is to see what happens when you change the temperature of the glow stick. If you change the temperature of the glow stick then the light shall dim or become brighter. We used three different glow sticks and three different beakers with water from 45C-70C, 0C and room temperature. A chemical reaction within the glow stick happens when you break the glass tube inside releasing the chemical, causes the glow stick to light up. When the glow stick was exposed to each beakers of water, the light emitted changed from temperature to temperature. The higher the temperature, the more light the glow stick produces. The lower the temperature, the …show more content…
When the glow stick was submerged into cold water, the light that was emitted was dimmed. When submerged into hot water the glow sticks light that was emitted would brighten up significantly. When sub merged into room temp for either cold or hot, the light wasn’t bright or very dim. Discussion and Analysis My hypotheses was supported by the data that was collected when performing this experiment. The glow stick emitted more light and brighter in hot water while the other glow sticks dimmed with the cold temperature water. The cause of the glow stick dimming is because of the reduced amount of energy produced therefore causing the glow stick particles to slow down. When heat was introduced again it causes the particles inside to release more heat causing a brighter glow stick. One of the error I noticed that can happen is leaving the glow sticks in the water past the 30 second interval. Another error that is easily over looked is having the right temps of water. The first trial was voided because a group member recorded incorrect temps causing the whole experiment to be
