Rubber Band
Hypothesis: My hypothesis is that a 40 degree angle will make a rubber band fling the furthest and that pulling it back 5 inches will also make it go far.
Procedure:
Get a ruler, rubber band and a protractor to measure the angle and make sure to control the variables like using the same rubber band.
Shoot it two times in each angle.
Shoot it two times in each inch.
Measure how far it went each time.
Put the data into a graph for each individual test.
Make an average for everything on a graph.
Data:
Data For The Inches
Data For The Angles
Abstract:
For my Science Fair, I wanted to find out what will make a rubber band fling the furthest distance. So out of the variables that I will be testing I decided that the angle and distance I pulled the band back would be the best to test. My hypothesis is that a 40 degree angle will be the best angle for it to go further and that stretching it back 5 inches will will make it go further.
The first thing that I had to do was gather all my things in order to test this experiment out. First I got a rubber band that will be used throughout the whole experiment. Then I needed to get a protractor and a ruler to measure the distance I pull the band back and the angle that it shoots. I also got goggles so that if something happened and the rubber band flung back, it wouldn’t hit me in the eye. Finally I got a measuring tape to see how far the rubber band shot.
So for the testing part of this I first got the things I need to make sure and angle and amount I stretched it back was the same. To summarize all the data, the best way to fling the band was stretching it back four inches and at an angle of 40 degrees which went 180 inches or nine ft. The best way to do it when you pull it back in inches is six inches since it flings 138 ft or 11ft six inches.
In conclusion, my hypothesis was proven correct as it shows using the angle of the way that you shoot the band will go further than how far you pull it back. When you pulled the rubber band back 6 inches, it went 138 inches but when you shoot the band at 40 degrees and a steady 4 inches pulled back, it shoots further.
Conclusion:
With my observations, the data that I tested was proven correct towards my hypothesis. I now know that if you shoot a rubber band at a 40 degree angle, it will go much further than a rubber band that you shoot when you pull it back six inches. I think that this experiment was accurate in some cases because I tested the shots three different times. To improve this, I could have tested everything five times giving me an ever better outcome since I tested everything so many times.
