I will measure the flexibility of boys and girls in Mr. Caslin’s class (Equal number of boys and girls) and test my hypothesis.<br />These are the three different measures of flexibility I used and how I measured them:<br />Split: inches from groin to floor. (The larger the result, the less flexible)<br />Torso and back: inches from toes to farther point (if kid doesn’t reach toes, measure is a negative number). (The larger the result, the more flexible)<br />Forward swing: feet from leg on the furthest points on a wall to floor. (The larger the result, the more flexible)<br />5824220393382531680154008120401320400812024301453886205241290393065-428625381000<br />Boy IDSPLIT (inches)Torso & Back (inches)Forward swing (feet)11713.621213.13152.5341342.11515-5.53.4682.53.67903.118112.53.11916.532.2101123.6119.513.9<br />Girl IDSPLIT (inches)Torso & Back (inches)Forward swing (feet)1823.112120.53.53703.114903.9592.1462.55.54.779-34.18914.119803.9107-63.211085.3<br />Girls: did better at split and forward swing.<br />Boys: did better at torso and back.<br />The girls outperformed boys in 2 of the three tests. The boys outperformed girls in 1 of the three tests.<br />5th Grade Girls are more flexible using their legs, and boys are more flexible using their backs.<br />Overall, girls are more flexible than boys.<br />My hypothesis was confirmed but only on 2 of the 3 measures.<br />Increase the number of boys and girls to include other grades and elementary schools.<br />Use a wider choice of flexibility tests.<br />I want to thank my teachers at Kinsey Elementary, Mr. Caslin, Mr. Miller, my classmates and my gymnastics coach at Flagstaff Gymnastics Center, Bernie Rede and Flagstaff Main Library.<br />
