Matter

This week we learned about matter. All matter  has something called an atom. An atom is a micro-object that can hold a solid together , make a liquid take the shape of its container, or let a gas move freely. What  is  also important is volume and mass. Volume is the amount of space the matter takes up. Mass is the amount of matter an object has.
