1. Choosing A Project:

TOPICS THAT INTEREST ME: CURRICULUM CONNECTION: Biology-the human body systems  the Solar System-space, the planets, moon, earth's rotation around the sun, how/why the planets rotate around the sun.

*Is it possible to extend the life of a glow stick using various methods such as heating it, refrigerating it, freezing it or placing it in a vacuum? *Does eye color affect a person's ability to distinguish colors?

MY TESTABLE QUESTION : What conditions make a glow stick glow for the longest time? (heating it, freezing it, refrigerating it, ect.)

INDEPENDENT VARIABLE: The temperatures

DEPENDENT VARIABLE: how long the glow stick glows for.

2. Investigate the Information:

 NOTES/FACTS:
 *  http://www.glowstickfactory.com/pages/Glow-Stick-FAQ.html <--- according to this website, the temperatures do affect how long the glow sticks glow for. When the temperature is between F59 degrees and F100 degrees, the glow stick is very bright, but does not last as long. is the temp. is lower then F59 degrees, the glow stick is not as bright but it lasts longer.
 * the longest lasting glow stick lasted 80 hours!
 * heat and humidity will affect how long the glow stick glows for.
 * apparently the color of the glow stick affects how long it glows for too!
 * Bioluminescence is generated by an enzyme-catalyzed chemoluminescence reaction, wherein the pigment luciferin is oxidised by the enzyme Luciferase

NOW THAT I'VE DONE SOME RESEARCH, I PREDICT THE ANSWER TO MY QUESTION WILL BE: I predict that in cooler temperatures the glow stick will glow for longer then it did in room temperature and warmer, and the yellow glow stick will glow for the longest period of time.

Plan A Procedure: <span style="color: #00ffa0; font-family: 'Arial Black',Gadget,sans-serif; font-size: 160%;">﻿ <span style="color: #00ffa0; font-family: Verdana,Geneva,sans-serif; font-size: 140%;">﻿ <span style="font-family: Verdana,Geneva,sans-serif; font-size: 140%;">I will take one of each color glow stick and test how long each color lasts for on a regular school day, in the dark, in the light, in a cold temperature, in a freezing tem <span style="color: #000000; font-family: Verdana,Geneva,sans-serif; font-size: 140%;">perature, and in a hot/warm temperature. After I collect this data i will enter it into my spread sheet. So basically I'm going to see what different temperatures and different amounts of light do to affect how long a glow stick lasts for.

<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 160%;">4. What I'll Need: glow sticks, a freezer, a refrigerator, and a heating source.

<span style="color: #000000; font-family: Verdana,Geneva,sans-serif; font-size: 140%;">I have these:a freezer, a refrigerator, and a heating source. <span style="color: #000000; font-family: Verdana,Geneva,sans-serif; font-size: 140%;">I need to locate these: glow sticks.

<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 160%;">5. Keeping Track - Proposed Data Sheet



<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 160%;">6. Analyze It All

<span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;"> Here's a Graph:

The data shows that. . . .The coldest temperature kept the glow sticks glowing the longest, and the warm temperature, although the glow sticks were the brightest, they died the quickest.

Therefore, I conclude that. . . .The green glow stick lasted the longest in the cold temperature.

But was my work valid? . . .I do hope my work was valid! The only thing that could of made it in valid was the fact that i used a school thermometer for the room temperature, and a different thermometer for the cold and warm temperatures.
