Oreo Rolling Distance Test

Contributors: Kyle Appleman, Dale Salmon, & Sam Basinait

 

EXPERIMENT:

  • To determine the distance an Oreo cookie will roll at different angles.

MATERIALS:

  • Ramp
  • Tape Measure
  • Dry Erase Marker
  • A Large amount of Oreo Cookies

PROCEDURE:

  1. Measure angle of ramp.
  2. Place Oreo on top of ramp vertically
  3. Release Oreo and watch as it rolls
  4. When Oreo stops moving, outline the Oreo's resting place.
  5. Repeat with different angles and more trials.
  6. Calculate average distance of each angle.

DATA:

  • Data table 1 shows the average distance of all angles done for each angle.
    Angle 11° 30° 45° 55°
    Average distance (cm) 313.71 295.25 619.25 500.33
    Average distance (ft.) 10.2 19.5 20.32 16.42
  • Data table 2 shows a Chi-Squared observed and expected outcome table.
    Angle 11° 30° 45° 55°
    Observed angles 313.71 295.25 619.25 500.33
    Expected counts 507.135 507.135 507.135 507.135

RESULTS:

  • Based upon the initial results it was found that Oreo's roll well on edge and when they fall they loose limbs and cannot achieve the same distance a second time.
  • After all of the rolls were done, it was determined that Oreo's are best consumed prior to being rolled across the floor.
  • Statistical Results
    • Ho: Oreo rolling distance and angle rolled at are independent.
    • Ha: Oreo rolling distance and angle rolled at are not independent.
    • Chi-Square = 113.96
    • Degrees of Freedom = 3
    • P-Value = .0000 (<.01) Therefore significant at p=.01'''
    • There is enough evidence to conclude that the distance an Oreo rolls is dependent on the angle at which it is rolled at.

POSSIBLE APPLICATIONS:

  • One could make wheels for tractors from Oreos, see this link for an artists rendition (link)
