A tennis ball and a tennis Racquet
● They use a tennis racquet to hit the ball to other side of the court, going back and forth.
● The tennis ball is used to bounce the ball back and forth until a player misses.

The evolution/history of the tennis racquets
● The first tennis racquets were actually the players hands and gloves to hit the ball. They then evolved into wooden paddles. In the 14th century they had a racquet with strings with a wooden frame. One hundred years later new improvements in technology they had laminating the technology on the racquets.

Polymers have improved
● The natural “gut” string is the important characteristics of strength, resiliency and surface roughness. The improved string is in the form of a filament of polymer material which is nylon. The result is a racquet string of improved stretch resilience, or resilience under tension.

The evolution/history of tennis balls
● The tennis balls were made of leather, stuffed with hair or wool.
● Now they are made from rubber and felt that increases the ball's wind resistance and control.

Research the football field/outdoor track and how polymers were
important.● On the football field
there are polymers which are polyethylene and polyurethane are included in the construction of similar football/track fields around the world.
