States of Matter
Remember that matter is the "stuff" that everything is made of. Matter has mass. It can be weighed. An object's mass is the measure of how much "stuff" or material makes up the object.
Matter also takes up space. The amount of space an object takes up or fills is its volume. A paper clip takes up only a small amount of space. A book takes up more space. It certainly wouldn't fit in the same space that a paperclip can fill up! And you take up more space than a book. You have a greater volume than the book or the paper clip.
Matter comes in four forms or states on Earth. Matter can be a gas like air. Matter can be a liquid like water. Matter can be a solid like an ice cube. Matter can also be plasma. The plasma state is very hot. It is only found on Earth in lightning. It is also found in stars.
