Viscosity Experiment With Marbles

The fun thing about science experiments for kids is that you can set them up easily and quickly with what you already have! Learn about viscosity of fluids with a simple viscosity experiment. Grab some marbles and find out which one will fall to the bottom first. We love science experiments that are fun and easy to do!

MARBLE VISCOSITY EXPERIMENT FOR KIDS

VISCOSITY OF FLUIDS

Friction is a force that is created when there is motion between two solid objects. Liquids can also have friction. This internal friction is called viscosity.

All liquids have different viscosities, which means some liquids flow more easily than others. Viscosity is a physical property of fluids. The word viscous comes from the Latin word viscum, meaning sticky. It describes how fluids show resistance to flow or how “thick” or “thin” they are.

Viscosity is affected by what the fluid is made of and the temperature of it. For example; water has a low viscosity, as it is “thin”. Hair gel is much more viscous that oil, and especially more than water!

Learn about the viscosity of fluids by having a marble race. Try this fun marble drop experiment below! You could even turn into an easy viscosity science project.
