Marble Viscosity Experiment

Activity extensions viscosity changes with temperature.

Marble viscosity experiment.

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. The weight of the marble which is the gravitational force also causes stress on the liquid. Density is a measure of how compact something is. Dropping the marble into a less viscous liquid like water will take much less time.

If the marble falls too quickly through the fluid to obtain accurate timing use a taller graduated cylinder or a lighter marble or both. Have students measure the viscosity of a fluid at a few different temperatures and graph the viscosity y axis vs. Expand on the experiment by estimating how long it will take for the marble to sink to the bottom of the jar. Honey corn syrup and molasses.

Viscosity races making science fun for kids says. In this viscosity experiment we attempt to refine the procedure by comparing fluids by dropping a marble through them. 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. Marble washed clean so that we don t waste the fluids we re dropping it through.

Timing the marble works best when using liquids that have a high viscosity ie. This is also a great opportunity to practice drawing and using tables as well as making predictions beforehand. Viscosity of a liquid can be calculated from the time elapsed provided that you know the height of the column and the densities of the sphere and the liquid. You ll need a homemade ramp an reply.

High viscosity fluids like honey and glue resist the changes caused by these forces the best. Viscosity is a properly of liquids that can be very important in very different applications from how the syrup flows out of your bottle to how blood flows through the human body to how lava. Viscosity races is a great experiment investigating viscosity for ages 5 and up.
