||Why are tennis balls fuzzy?
|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:
||I was hoping to learn why tennis balls are fuzzy.
|What was your hypothesis?:
||That the ice cube covered with flower would be much more easier to pick up then the plain ice cube.
|What materials did you use in your experiment? List them all.:
||Two plates, flour, ice cubes, tongs.
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:
||I put an ice cube on the plate and tried to pick it up with the tongs. Then, I put flour on the plate, rolled the ice cube in flour, and then I tried again.
|What were the results of your experiment?:
||The one with the flour on it was much easier to pick up then the ice cube without flour.
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?:
||My hypothesis was correct. The ice cube that had flour on it was much easier to pick up then the ice cube with no flour.
|Spend a few minutes learning about the scientific principles involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.:
||In this experiment, the chopsticks took place of the tennis strings on the racket and the ice cubes took place of the unfuzzy ball and the fuzzy. In order for the strings to “grab” the ball and give it a deceptive spin, there needs to be enough friction in the collision. The fuzz provides the friction- just as the flour provided friction for the ice cube.
