Explanation

Oils in which the marbles had slowest velocity had the highest viscosity. The weight of the marble, which is the gravitational force, causes stress on the liquid. High viscosity fluids like the extra virgin olive oil resist the changes caused by this forces the best.

Viscosity

Percent Error

Viscosity is a measure of a fluid's resistance to flow. A fluid with large viscosity doesn't want to move. A fluid with low viscosity flows easily.

Peanut Oil 0.71s 0.76s 7%

Grapeseed Oil 0.75s 0.62s 21%

Granola Oil 0.73s 0.74s 1%

Olive Oil 0.80s 0.67s 19%

We think that the extra virgin olive would have a higher viscosity than any other oil tested, and the grape seed oil would have the lower viscosity.

Racing Marbles to Discover Different Oil's Viscosity

By: Katrin Esaa, Beatriz Scaciota, Tessa Grund

  • 4 Marbles
  • 4 Glasses (about 650ml each)
  • Grape seed oil
  • Extra virgin olive oil
  • Canola oil
  • Peanut oil
  • Stopwatch

After several trials, we determined that the peanut oil had the most viscosity. It took longer to reach the bottom of the peanut oil than it did with any other oil. The granola oil had the least viscosity. Once the marbles would drop, the marble in the granola oil usually landed first.

Trial 1:

Trial 2:

Peanut Oil 0.84 seconds

Grapeseed Oil 0.76 seconds

Granola Oil 0. 62 seconds

Olive Oil 0.89 seconds

Peanut Oil 0.76 seconds

Grapeseed Oil 0.62 seconds

Granola Oil 0. 74 seconds

Olive Oil 0.67 seconds

Procedure

Dropped the marbles at the same time and see which marble hits the bottom first and which one hits the bottom last.

Curiosity

The viscosity of volcanic lava is important in working out how it will behave and can be used to explain the shapes of volcanoes. Lava that has a high viscosity tends to flow slowly and it's associated with high explosive eruptions.
