Marble has been making a powerful statement in architecture and interiors ever since the dawn of civilisation—there’s simply no denying the everlasting beauty of this natural stone. These days quarried in about 32 countries, the market for marble is mainly dominated by Italy, China, India.

Key conceptsPhysicsFrictionSolidsLiquidsIntroductionHave you ever tried to squeeze honey or syrup out of a bottle at breakfast on a chilly winter morning? Do you notice that it's harder to do that than on a hot summer day? As the liquid gets colder, its viscosity, or resistance to flow, increases. 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 flows out of a volcano. In this project you will learn a little bit about viscosity by holding a marble race!BackgroundYou experience friction all around you. It is what allows your shoes to grip the floor so you don't slip and it's what makes your bike come to a stop when you squeeze the brakes.

This type of friction is a force that resists motion between two solid objects. Liquids, however, have friction, too—not just against solids (for example, water against a drinking glass)—but also internal friction, the liquid against itself.

This internal friction is called viscosity. Different liquids have different viscosities, which means some liquids flow more easily than others.

You will notice this if you think about squirting water out of a bottle or squirt gun. Imagine how much harder that would be to do with cold syrup!There are several different ways scientists can measure the viscosity of a liquid. One method is called a 'falling sphere viscometer,' in which you drop a sphere (such as a marble) through a tube filled with liquid. By measuring how long it takes the marble to fall and how far it travels, you can figure out the liquid’s viscosity.

You won't need to do any calculations in this activity—but you will get to 'race' marbles by dropping them in different liquids. Will viscosity affect how fast the marbles fall?

Certain alloy additions can also improve the abrasion qualities of steel. The higher graphite content in cast iron creates a graphitic dry lubricant that allows solid surfaces to slide against each other without deteriorating surface quality.Steel wears more readily than iron, but may still be resistant to certain types of abrasion.
