Swimming Sensation

Overview

Objectives/Goals Our science fair experiment is about swimming. We chose to do a project on how, and if a swimmer's arm span affects their speed in the pool, since we are both swimmers and it is an area of interest for the both of us. We tested the hypothesis: If a swimmer has longer arms, he/she will complete a length in less time than a similarly trained swimmer. Methods/Materials Materials # Tape measure # Stopwatch # Paper # Pencil # Competitive swimmers We conducted our experiments on 19 Masters Swimmers, ranging from ages 23-64 years old.We measured their body to arm span ratio and recorded it on a piece of paper. We then had them swim a 25 yard length in the pool and we recorded their times Results According to our data, we found that only the swimmers with exact body to arm span ratio of 1:1 that swam proved our hypothesis correct. Conclusions/Discussion Based on our results, we cannot conclude that our data proves our hypothesis. This does, however, lead us to believe that further testing with more control factors could result in a relationship between the arm span and speed of the swimmers.
