Marble Viscosity Experiment

Marble washed clean so that we don t waste the fluids we re dropping it through.

Marble viscosity experiment.

Timing the marble works best when using liquids that have a high viscosity ie. If the marble falls too quickly through the fluid to obtain accurate timing use a taller graduated cylinder or a lighter marble or both. 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. 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.

This is also a great opportunity to practice drawing and using tables as well as making predictions beforehand. Dropping the marble into a less viscous liquid like water will take much less time. Viscosity races making science fun for kids says. Then set a timer and find out how close your estimate was.

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. Have students measure the viscosity of a fluid at a few different temperatures and graph the viscosity y axis vs. Activity extensions viscosity changes with temperature.

Honey corn syrup and molasses. Viscosity of liquids is often very temperature sensitive with most liquids and gases becoming less viscous thinner as they heat up. High viscosity fluids like honey and glue resist the changes caused by these forces the best. Viscosity races is a great experiment investigating viscosity for ages 5 and up.

It is the ratio of mass to volume and is a. In this viscosity experiment we attempt to refine the procedure by comparing fluids by dropping a marble through them. Expand on the experiment by estimating how long it will take for the marble to sink to the bottom of the jar.
