If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low density. Mass is the amount of matter in an object. Volume is how much space the object takes up.

Note: The NGSS Structure and Properties of Matter for 5 th grade, Performance Expectation 5-PS1-3 states “density is not intended as an identifiable property. Assessment does not include density or ...
