Title
Fishing Line Breaking Point

Broad Question
Does 10lb. test break at 10lbs. of weight?

Specific Question
Do different brands of 10lb. test fishing line affect the weight it can withstand before breaking?

Hypothesis
It is hypothesized that the Spiderwire EZ Mono 10lb. test will exceed the manufactures weight limit. This is based on the motto of the product.

Graph of Hypothesis




Independent Variable:
Brands of fishing line

Dependent Variable:
Breaking point weight

Variables That Need To Be Controlled:
10lb. test line, Same five gallon buckets, same length of different brands of line, Same type of sand to put in the bucket. Same knots used to tie line to bucket and hook, Same method of adding sand to bucket

Vocabulary List That Needs Explanation
Pound Test- amount of pressure that can be put on a line before it breaks Force- strength or power exerted upon an object

General Plan
For the experiment take three different types of 10lb. test fishing line. One at a time take one brand of fishing line and tie it to the metal hook connected to the top of the garage. Then tie the other end of the fishing line to a five gallon bucket with lines on it that show where 5, 7.5, 10,12.5, and 15 pounds of sand are. Next slowly pour the sand into the bucket, until the fishing line breaks. This procedure will then be repeated using the two other brands of 10lb. test fishing line.

Potential Problems And Solutions
The bucket of sand could drop causing it the crack and spill, I would go and get another five gallon bucket down stairs and go get more sand at the Town Hall.

Safety Or Environmental Concerns
The fishing line could snap unexpectedly and fall on my foot.

Detailed Procedure
<span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">1. Purchase three different brands of 10lb. test fishing line; Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">2. Take a five gallon bucket and fill it with fifteen pounds of sand from the Town Hall. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">3. Screw the metal hook into the top of the garage, to tie one end of the fishing line to test the strength. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">4. Take another 5 gallon bucket and place it onto a scale, slowly pour in the sand and mark a line with sharpie at the 5, 7.5, 10, 12.5, and 15 pound marks. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">5. Using one brand of fishing line, cut a 6.5ft. piece of line. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">6. Tie one end to the metal hook and the other to the bucket handle. (Make sure to leave no more than a 6ft. span of line between the bucket and hook. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">7. Slowly start to pour sand into the 5 gallon bucket with a measuring cup, once you reach each marked point, stop and record your data. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">8. When the line snaps, put the bucket of sand onto the scale and record the final weight of the bucket. <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">9. Repeat steps 5 through 7 for 10 trials for each brand of fishing line

Conclusion
<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-decoration: none; vertical-align: baseline;">An experiment was conducted to see what brand of ten pound test fishing line had the highest breaking point. The independent variable was different brands of 10lb test fishing line, and the dependent variable was breaking point force. The experiment that was conducted used three brands of fishing line, Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex. Berkley Trilene held the most weight. The end result of the experiment was that Berkley trilene came in first with an average breaking point weight of 9.1 pounds. Spiderwire EZ Mono came in not that far behind with an average breaking point weight of 6.7. Just to reiterate, these brands of fishing line are 10 pound test, meaning that they should withstand a weight of 10 pounds of force. Zebco Omniflex came in with an average of 5.05 pounds.

Discussion
<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-decoration: none; vertical-align: baseline;">The experiment question was, do different brands of 10 pound test affect the weight it can withstand before breaking? The answer to this question is yes, the three different brands of 10 pound test fishing line all had different breaking points. The hypothesis that was made was not supported by the results. In the hypothesis, Spiderwire EZ Mono should have withstood the most force, but after conducting the experiment, Berkley Trilene can out on top with an average breaking point weight of 9.1 pounds, while Spiderwire EZ Mono only had an average breaking point of 6.7 pounds. In the experiment, there was a relationship between the brand of fishing line and the amount of force it can hold. The experiment showed that each brand had a pattern, in the sense that all of the breaking weights for that brand were very similar. There were only a few minor problems throughout the experiment, and were easily resolved. One of the main problems was that the fishing line would sometimes have a knot or tension, which would easily mess up my results. This problem was easily fixed by just getting another six and a half foot piece of line. Another problem that was faced while conducting the experiment, was when the sand would come out of the bucket to fast or in a big clump, making the bucket shake and move, and sometimes making the line break. This would then cause the trial to be redone. <span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-decoration: none; vertical-align: baseline;">If the experiment were to be run again, I would try to find a way to slowly and evenly distribute the sand around the inside of the bucket. I would also use non- rock sand, because the rocks would cause tension in the line when it would bounce around. The last thing that would have to be changed in the experiment, would be to tie different knots around the bucket handle and metal hook. This caused only one problem, that on the fifth trial using Spiderwire EZ Mono, the bucket fell off the line because of a poorly tied knot around the handle. The research that was found off the internet to find out what the different brands of fishing lines were made out of, and how each and every one of the companies test their lines. Someone in the future could look at the results and see how the experiment was conducted and what results were found. They could then take what they learned from the experiment and make a more efficient and/or easier way to test fishing line in the future. The results of the experiment can be of benefit to all avid sportsmen and fishermen alike. This information can be used to help avid fishermen maybe think twice before they use Zebco Omniflex or Spiderwire EZ Mono, and to inform them of the results and discoveries. It could also benefit the fishing line companies themselves, to show them how the experiment was ran and show them how their line did next to their other competitors.

Abstract
<span style="background-color: transparent; display: block; font-family: 'Times New Roman'; font-size: medium;"><span style="background-color: transparent; color: #000000; font-family: 'Times New Roman'; font-size: 16px; text-decoration: none; vertical-align: baseline;">An experiment was conducted to see what brand of ten pound test fishing line had the highest breaking point. The independent variable was different brands of ten pound test fishing line, and the dependent variable was breaking point force. The experiment that was conducted used three brands of fishing line, Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex. Berkley Trilene held the most weight. The hypothesis for this experiment was that the Spiderwire EZ Mono, would be the brand of fishing line that would hold the most force. The hypothesis that was predicted, didn’t match the result of the experiment. The end result of the experiment was that Berkley Trilene came in with an average breaking point weight of 9.1 pounds, the highest of the three brands. Spiderwire EZ Mono had a breaking point of 6.7 pounds, and Zebco Omniflex ha a breaking weight of 5.05 pounds. It was a surprise that Spiderwire EZ Mono did not hold the most force, because all of the research that was done said that Spiderwire is the highest quality line. Fishermen should now be using Berkley Trilene for fishing line because of the weight it held.
