Rubber Band Stretching

Conclusion

       From our results we were unable to conclude a relationship between the vertical stretch of a rubber band and its horizontal stretch when hit by a BB. Our hypothesis that increasing vertical stretch would decrease horizontal stretch was neither confirmed nor rejected. We determined that other variables, such as switching the rubber band, placement of the BB when it hit the rubber band, and overuse caused variation that made our graph of horizontal stretch vs. vertical stretch random.

       Removing or decreasing the effects of these unexpected factors would have helped us determine if there was a relationship between vertical and horizontal stretch. To do this we could have positioned the BB gun closer to the rubber band in order to improve the accuracy of the hit. Buying a box of identical rubber bands would have reduced the variation between rubber band switches. Switching the rubber band between each trial would have removed any variation from overuse.
