In this experiment we are testing to see in what grade you have the fastest reactions. We have decided to test this on an x-box game called “Dance Dance Revolution.” This game involves a lot of concentration, rhythm and fast reactions. We gathered our materials and set it up in a small, closed -in room. Sixteen children were tested individually, one boy and one girl from grades 5-12. Each person danced to a total of three songs. The first song is called “Whip It.” It is a slower paced song and has 130 steps. The second song is called “Butterfly.” It is a little quicker than the first and has 160 steps. The third song is “Together Forever.” It is the quickest song and has a total of 172 steps. After each song is finished the x-box game will mark you on how well you followed each step. Each step is rated in one of these categories, Perfect, Great, Good, Almost, O.K. and Boo. After each song is over we mark down the points that each person got on each song. Our results showed that grades 11&12 had the fastest reactions!
