Density: Sink or Float

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

What does it mean if an object sinks in water?

Back

If an object sinks in water, it means that its density is greater than the density of water.

Front

What does it mean if an object floats in water?

Back

If an object floats in water, it means that its density is less than the density of water.

Front

Which is denser: oil or water?

Back

Water is denser than oil.

Front

What is the density of water?

Back

The density of water is approximately 1 gram per cubic centimeter (g/cm³).

Front

What happens to objects with a density less than 1 g/cm³ in water?

Back

Objects with a density less than 1 g/cm³ will float in water.

Front

What happens to objects with a density greater than 1 g/cm³ in water?

Back

Objects with a density greater than 1 g/cm³ will sink in water.

Front

What is an example of a material that floats?

Back

An example of a material that floats is a rubber duck.

Front

What is an example of a material that sinks?

Back

An example of a material that sinks is a marble.

Front

How can you determine if an object will float or sink?

Back

You can determine if an object will float or sink by comparing its density to the density of the liquid.
