====The purpose of this study was to determine how lacrosse balls were affected in many different ways. A lacrosse ball is made out of hard rubber, and gravity is a force that helps to pull one small mass to one bigger mass, a liquid is a range of small temperatures and pressure, and clay is made of weathering and erosion of rocks. Seven experiment using lacrosse balls were performed with methods that tested each ball using speed, height/bounce and coatings. It was determined that the many experiments on different brand of lacrosse balls and test of lacrosse balls being coated, being heated or being cooled yield many interesting results which you will see below. The results showed that the heavier the coating the less bounce the lacrosse ball had and the speed of the lacrosse ball was effected by different brands of lacrosse balls.====

Experimental improvements and future experiments
====should have dropped the lacrosse ball higher than it was, which would have made it bounce higher. there should have been stickier clay so that it would have bonded to the ball better. For another experiment clay would be used and different liquids would be put on it to see how it was effected.====
