Bounce that Ball Ernmarie Guevara and Kerry Small Vancouver Technical Secondary Floor Location : J 107 P

We based our project on basketball and what kind of flooring makes a ball bounce higher. The idea came from my partner who plays basketball for her teams.

We first collected alot of information from numorous websites, but the information that we collected weren't all true. So, we consulted with our mentor, my dad who is a professional engineer. He ran through our paragraphs and told us what was untrue about our project. So we went back and redid it all. The next step was to do the actual testing. We first gathered all of the materials used, such as a ladder, a camera, a basketball, and a tape measurer.

We measured the hieght kerry reached up to, which was 7ft 4 inches. She held it there and dropped the ball at the exact hieght no more no less, useing no force. Take in thought that the ball in pumped well. We video taped the ball bounceing for each of twenty trials for the 5 different kinds of floors, and then used a slow motion-ing program on a comptuer. The flooring was already installed on to the floor.

Next we did a T-test on the averages that we got. We used a 95% confidence interveral. Meaning that 95% of the time that you bounce a ball at a hieght of 7ft 4inchs that the averages will turn out to be almost the same as our results.

We next printed everything out and made gave it to my dad, who checked over everything for any errors possible. After printing everything out again and laying it out on the poster board. We soon tumbled on more errors that were oviouse that we didn't recognize earlier. So we had to redo some of the steps to the process.

This concludes our project Summary.
