Poster with Activity Guide
Did you know that the speed of launch of a golf ball is 170 mph?; that a ball with a rough surface flies more easily through the air than a smooth one?; that a ball always bounces in the direction of its spin? The way you play a game depends on the ball you use. How a ball spins, bounces, and moves through the air determines the kinds of plays you can make. This poster from the Exploratorium describes how the characteristics of different balls and the sizes of playing fields correspond to their respective sports. An 11"x17" Activity Guide provides interesting facts and ideas for experimentation.
