Marble Viscosity Experiment

In this viscosity experiment we attempt to refine the procedure by comparing fluids by dropping a marble through them.

Marble viscosity experiment.

Dropping the marble into a less viscous liquid like water will take much less time. Density is a measure of how compact something is. Expand on the experiment by estimating how long it will take for the marble to sink to the bottom of the jar. July 1 2013 at 1 23 pm done a viscosity race before but this time i wanted to do it on a bigger scale and really get the kids.

Timing the marble works best when using liquids that have a high viscosity ie. Honey corn syrup and molasses. Have students measure the viscosity of a fluid at a few different temperatures and graph the viscosity y axis vs. You ll need a homemade ramp an reply.

Viscosity races making science fun for kids says. It is the ratio of mass to volume and is a. Activity extensions viscosity changes with temperature. Marble viscosity race aerodynamics science fair projects hydrdynamics model experiments for cbse isc stream students and for kids in middle school elementary school for class 5th grade 6th 7th 8th 9th 10th 11th 12th grade and high school msc and college students.

Then set a timer and find out how close your estimate was. Viscosity of liquids is often very temperature sensitive with most liquids and gases becoming less viscous thinner as they heat up. The weight of the marble which is the gravitational force also causes stress on the liquid. High viscosity fluids like honey and glue resist the changes caused by these forces the best.

If the marble falls too quickly through the fluid to obtain accurate timing use a taller graduated cylinder or a lighter marble or both. Marble washed clean so that we don t waste the fluids we re dropping it through. Viscosity races is a great experiment investigating viscosity for ages 5 and up.
