 * The Effect of Temperature On Glow Stick Brightness**

With Halloween occurring this month Brayden and I wondered how we should store our glow sticks. We questioned if the general consensus of storing the sticks in cold temperatures was the best method. Upon questioning the method we read into on what makes up a glow stick and how it works. We found out that glow sticks are translucent plastic tube congaing isolated solutions with a glass capsule covering the solution of phenyl oxalate and fluorescent dye with hydrogen peroxide on the outside of the glass. "After the glass is broken and the solutions mix [creating phenol], the glow stick glows". ("Glow stick") Florescence and phosphorescence is the emission of the light from the glow stick. That process is called chemiluminescence. ("Science Fair Projects"') We also learned that " heating a light stick will accelerate the chemical reaction" ("How Light Sticks Work") emitting a stronger glow. Lastly, we learned some uses for glow sticks. "Glow sticks are popularly used during parties, night parades, concerts and festivals. Glow sticks are also useful in places that do not have a power source and they are regularly used by campers, divers and military personal".("Science Fair Projects"')

3 Beakers/Cups- Free 6 Glow Sticks $6 (Dollar General will be cheaper -Andrew Pruitt) 6 cups of water- Free 4 Thermometers- $10 Timer- Free
 * Materials:**


 * Independent Variable:** Water temperature the glow sticks were stored in.


 * Dependent Variable:** Glow stick brightness and length of glow.

If a glow stick is put in cold water then the glow stick will glow longer.
 * Hypothesis:**

Test 1: Walmart Brand 1) Fill 3 graduated cups up with 1 cup of room temperature water each. 2) Put glass #1 on a hot plate and warm up to 120 degrees fahrenheit. 3) Put ice in glass #3 to lower the temperature to 40 degrees fahrenheit. 4) Leave cup #2 at room temperature 5) Once you have all 3 cups at their desired temperatures break and place a single glow stick in each cup. 6 ) Let the glow sicks sit in the water for 60 minutes, checking temperature and recording data every 15 minutes. 7) After the 60 minutes remove the glow stikcs from the water and place in dry area. 8) Compare glows of each stick. 9) Finally, place glow sticks in dark area with timer, timing how long each stick glows and record data.
 * Procedure:**

Test 2: Brite Lite Brand 1) Fill 3 graduated cups up with 1 cup of room temperature water each. 2) Put glass #1 on a hot plate and warm up to 120 degrees fahrenheit. 3) Put ice in glass #3 to lower the temperature to 40 degrees fahrenheit. 4) Leave cup #2 at room temperature 5) Once you have all 3 cups at their desired temperatures break and place a single glow stick in each cup. 6 ) Let the glow sicks sit in the water for 60 minutes, checking temperature and recording data every 15 minutes. 7) After the 60 minutes remove the glow stikcs from the water and place in dry area. 8) Compare glows of each stick. 9) Finally, place glow sticks in dark area with timer, timing how long each stick glows and record data. 10). Compare stick brightness and glow length to the sticks in test 1.
