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 is less dense than water?

Back

If an object is less dense than water, it will float on the surface of the water.

Front

What does it mean if an object is more dense than water?

Back

If an object is more dense than water, it will sink when placed in water.

Front

What is the tool used to measure the volume of liquids?

Back

The tool used to measure the volume of liquids is called a graduated cylinder.

Front

What happens to a key when placed in water?

Back

A key will sink in water because it is more dense than water.

Front

True or False: The density of a specific type of material never changes.

Back

True.

Front

How do you arrange liquids from most dense to least dense?

Back

You arrange them by comparing their densities; the one with the highest density goes first.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the object's density compared to the fluid's density.

Front

What is an example of a less dense object?

Back

An example of a less dense object is a rubber duck, which floats on water.

Front

What is an example of a more dense object?

Back

An example of a more dense object is a rock, which sinks in water.
