Back

Cork is an example of a material with low density; it floats on water.

Front

What is an example of a material with high density?

Back

Metal is an example of a material with high density; it sinks in water.

Front

How can we classify matter?

Back

Matter can be classified by its state (solid, liquid, gas), density, and temperature.
