Methods The materials I used needed to be as close to the real life situation as possible. Materials included:
• 2 footballs (same size)
• Thermometer
• Air pressure gauge
• Air pump w/ Ball needle
• Refrigerator
• Freezer
• Paper & Pencil
The NFL Scandal “Deflategate”, is what boosted this experiment from ever happening. Although the NFL believes that the Patriots intentionally underinflated the footballs, not enough proof has been shown to prove them guilty. Three trials were conducted to find the outcome of this experiment. However, using more footballs and more trials, would lead to more correct and accurate work. Using atmospheric pressure to change air pressure with a fridge and freezer does test the hypothesis because this operation…show more content… With one trial taking 2 hours each, that adds up to 6 hours needed to find the appropriate data for this experiment. Safety would not be a problem during this scientific process.
The procedures of this experiment are:
1. Gather materials
2. Inflate 2 footballs at 13.5 psi (League limit)
3. Drench footballs in water till all surfaces are wet
4. Place footballs in 50°F conditions
5. Check air pressure every 30 minutes 4 times
6. Record…show more content… In trial one (50°F) the air pressure dropped slower than all the trials. The lowest psi reached was 12.5 (See Appendix 1). The average for Ball #1 was 12.9 psi, which is .4 psi higher than as low as the NFL standards can go. The average for ball #2 was 12.7psi. The lowest air pressure recorded in the experiment was 9.5 which was found in trial #3, Ball #1 (See Appendix 1). All trials support the claim that atmospheric pressure lowers air pressure.
Many questions can be asked about this experiment. Many of the answers include variables that may have changed the outcome or made it invalid. One could be, how could the 2 balls that are in the same location have different air pressures? A possible answer could be whether or not the “coldness” was distributed unevenly. Even if a couple objects are spaced 1 inch apart, there might be some difference in temperature. Other variables include exposure to water, and the food located in the freezer & fridge while the experiment was taking
