2 pieces of equipment and how its used in the sport:<br />I chose the volleyball and the volleyball net. Two very important pieces of equipment.<br />Volleyball- a large, usually white inflated ball used to play volleyballUsed for definition from: Encarata Dictionary <br />Volleyball net – a net hung by two poles used in the sport of volleyball<br />http://www.topendsports.com/image/clipart/volleyball<br />
Describe the evolution/history of the 1st piece of equipment you chose ..how has this piece of equipment changed through the years? <br />History of the volleyball: the first official ball used in volleyball was disputed – some sources say that Spaulding created the first official ball in 1896m while others claim it was created in 1900. The ball is made out of natural or synthetic leather. It is inflated with compressed air. The ball must have a circumference between 65-67 centimeters and weigh between 260-280 grams.<br />http://www.buzzle.com/articles/volleyball-history-court-and equipments.html<br />How has “the volleyball” changed through the years:There are so many different types of volleyballs since the beginning. The first volleyball was usually just white. We now have these different types & kinds: Indoor/outdoor, rubber, leather vs. synthetic composite and wide range of colors<br />http://www.allstaractivities.com/sports/volleyball/volleyballs.htm<br />
Describe how polymers have improved this 1st piece of equipment:<br />Since the days when kids played with rubber balls polymers have improved it from then.<br />Polymers add leather and synthetic composite to make the volleyball. <br />http://www.allstaractivities.com/sports/volleyball/volleyballs.htm<br />http://image.funexpress.com/feimg/5_857.jpg<br />orientaltrading.com<br /> http://minisportsballs.putyournameonit.com/images/sportsball_photos/volleyballs.gif<br />
Describe the evolution/history of the 2nd piece of equipment you chose ..how has this piece of equipment changed through the years?<br />History of the volleyball net: The first volleyball net was borrowed from tennis and it was only 6’6” high. (The average American was shorter in the 19th century). <br />The net moved from 6 feet 6 inches (1.98 m) high to over 7 feet (2.13 m): 7 feet 11 5/8 inches (2.43 m) for men and 7 feet 4 1/8 inches (2.24 m) for women. Co-ed teams play with the men’s height. There are also different types of nets:<br /> Indoor/outdoor, in ground and portable.<br />http://www.athleticscholarships.net/history-of-volleyball.htm<br />How has the volleyball net changed through the years:<br /> With the use of polymers, we now have many different types of nets.

Research football field/outdoor track and discuss how polymers were important to the construction of it and other fields like it.<br />Carbon is a essential part of polymers. “Polymers are made up of repeating monomers - which are small carbon containing covalent compounds”. Another word for polymer is plastic. We all deal with plastics every day - in clothes, shoes, cars, soda and water containers. There are also a lot of polymers used in sports. From the football made from polyurethane to the football field turf made from polyethylene. Both of these polymers are man-made polymers. There are a lot of natural polymers also still in use in the sports industry. For example tennis balls are usually covered in wool, which adds consistency and durability to a tennis ball. <br />So the next time you are watching any kind of sport, chances you are seeing chemistry in action.<br /> http://blogs.lib.ncsu.edu/chem/entry/polymers_in_sports<br />http://en.wikipedia.org/wiki/American_football<br />http://en.wikipedia.org/wiki/Track_and_field_athletics<br />
