  1. Cool light:the effect of temperature on chemiluminescence October 8, 2012 An experiment done by Felicia Salzmann for ECH2050

  2. Hypothesis : That a change in temperature will effect the rate of the chemical reactions in a glow stick 4” glow sticks Unknown ingredients Four colors: blue, yellow, pink, purple

  3. Just cracked – 1 Min Room temperature

  4. Left in hot water for 5 min

  5. Hot water Room Temp.

  6. 1 min after freezing 10 min after freezing

  7. Conclusion: Based on the increase of brightness when immersed in hot water it is evident that the chemical reaction within the glowsticks was proceeding at a faster rate. The opposite was true regarding the glowsticks in the freezer, which caused the reaction to slow down to the point where no light was given off.
