3 basketballs: 1 basketball at 8 psi, 1 basketball at 9 psi and 1 basketball at 6 psi (psi = pounds per square inch) 1 Air pump; 1 Pressure gauge; 1 “Yardstick” style tape measure; 2 Different surfaces: 1 wood surfac,; 1 concrete surface; Marker (mark each basketball with the correct psi) Experimental Procedure:
Start with the basketball inflated to zero psi (pounds per square inch) on the first drop. Raise the basketball as high as possible above your head, and then drop it in front of the measuring...
The molecules push and press on those surfaces, exerting pressure on them. Air pressure allows your basketball to keep its round shape and remain hard and bouncy. If air escapes from the ball, the pressure inside the ball changes. Air pressure is measured using psi, or pounds per square inch. A basketball needs 8 psi to be properly inflated.
By ScottM. Finding ways to demonstrate the use and knowledge gained from science in the form of a project or experiment is a way of using creativity to show how basic ideas or scientific theories can be taken out of a lab and applied to the real world. The game of basketball is filled with science. Physics, gravity, motion, action and reaction are all factors in the game, and there are more than a few ways to use basketball to demonstrate key scientific concepts.
Drop a basketball inflated to 8 psi from a height of 6 feet (1.8 meters). Be sure that the bottom of the ball-not the top-is at the 6-feet line when you drop it. Observe, mark, and measure the height of the ball's bounce, remembering to measure at the top of the ball. Record your measurement.
Let the ball bounce until it stops, and then stop recording. Use the pressure gauge to release some of the air pressure from the ball. Record the new pressure reading in your data table and repeat steps 4 and 5. Keep releasing pressure and repeating the experiment until the ball no longer bounces.
Increase the pressure within the ball to 7 psi, then repeat steps one through three. Once you've completed all the steps, you'll need to average the height of the bounce recorded in each of the three trials for each step. To find the average, add the three measurements together, then divide the total by three.
