To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid.

Hypothesis: If a marble is dropped into dish soap and corn syrup, than I predict that the marble in the dish soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the dish soap. Also, the particles in the corn syrup are more compact than those in the dish soap. This makes the marble sink faster in the dish soap than the corn syrup.

Apparatus: * 2 identical marbles * 250 Graduated Cylinders of 250mL * 250mL of dish soap * 250mL of corn syrup * 1 timer/stopwatch

Procedure: 1.

It is very difficult for large particles to move past each other unlike small, tiny particles, like those in the dish soap. The particles in the dish soap are very small and can move more freely and quickly. In the dish soap, the particles are very small and can move past each other easily when compared to the particles in the corn syrup. Another reason also contributed to the result of this experiment. Attraction. Some types of particles tend to attract more than others and that is exactly what happened in the corn syrup. The particles in the corn syrup attracted more than the dish soap. The large particles in the corn syrup held tightly to each other, that when the marble fell in that it made it hard for the marble to pass through more than one particle at a time. IN the dish soap, the particles did not attract as much as the corn syrup which let the marble move easily and quickly through the liquid. The strength of attraction as well as the particle size is important in determining a fluid’s viscosity.
This viscosity experiment can be used in real-life when making sun-tan lotion as well as other cosmetic products. It is important for the lotion to be viscous because the lotion could not be applied and spread around the body if the cream was not viscous enough to suit its use. It would drip all over you! It wouldn’t dry or stay in one place. Many well-known businesses hire highly educated scientists to calculate the right viscosity level and if it is
