Glow Sticks Experiment

Background: Fishermen use many different types of baits and lures to attract fish of different shapes and sizes. One of these types that certain fishermen use are lighting devices that attract fish. Some fish may be attracted to illuminated lures because they live in poor visibility conditions and low light. It is also important to light the bait so the fish could see it. The brighter the light the better, but since electronic light devices are expensive and unreliable, glow sticks prove to be more efficient. However, it is not as efficient as it may seem.
Glow-sticks are a quite interesting and very useful creation. They provide a short-term light source and are self-contained. Since it is self-contained, it does not need an outside energy source to do …show more content…
The levels are 7 degrees Celsius and 40 degrees Celsius.
Dependent variable: The dependent variable is the brightness of the glow-stick that was measured in the length of how long the light reflected in inches.
Controlled variables: Glass size, amount of water, type of glow-stick, size of glow-stick, the setting of the glow-stick, how long the glow-stick is placed in the water, how long the glow-stick is handled and shaked and cracked.

Experimental Control Group: The standard of comparison is a glow-stick that is the same type of glow-stick to the others but is not affected by the different water temperatures. The reason for not allowing the glow-stick to be placed in the different water temperatures is because the experiment is testing the glow-sticks at different water temperatures, so it is reasonable to have the standard of comparison to be a glow-stick at the temperature all the other glow sticks have originally started at.

Materials: There are three beakers, water, beaker of ice, a hot plate, three thermometers, three glow sticks, a small plastic ruler, and clear tape.
