Squash Ball Experiment Group:2 (Amanda,Farah,Jaweria,Farah,Micah & Rawan)Title: Testing effects of temperature on the bounce of a ball.Aim: To see how changing the temperature of a ball affects the bounce of a squash ball.Hypothesis: I think that the higher the temperature, the higher the bounce of the ball. This is because when the temperature is high, the particles get more kinetic energy and are a lot more active. I think that this will give the ball a higher bounce.Variables:Controlled: The height from which the ball is bounced, the size of the ballDependant: The height, direction and speed of the ball when it bouncesIndependent: The temperature of the ballApparatus:Squash ballBunsen burnerThermometerBeakerGauze matTripodWaterMeter ruler stickTongsGogglesMatchesMethod:First, get all of your apparatusThen you record the temperatureRecord the temperature in your tableBounce the ball alongside a wall so you can see how high it bounces using your rulerWrite down your resultDo this at least two times to be more accurate with your resultsHeat the water ten degrees higher with the squash ball in itWhen the water is 10 degrees higher, take out the ball using the tongs so you don't get burntThen take it out and repeat the experimentRepeat this experiment, heating the water and putting in the ball until you get around 5 temperatures and/or the ball stops heating upRepeat this experiment over again if you have more time so that your results can be more accurate,Results:
Height of the Bounce (cm)
Data Analysis:The data shows me that the higher the temperature of the ball, the higher the bounce. This means that the particles are a lot more active in the squash ball as their temperature is raised. The graph above shows you that there were a few inaccurate results, but most followed the trendline.Conclusion:In conclusion, my hypothesis was correct; the hotter the ball, the higher the bounce. It also proves that my views about the particles becoming more...
