* They are all made of matter: Everything in the universe, including these objects, is made up of matter. Matter is anything that has mass and takes up space.
* They have physical properties: Each object has unique physical properties such as:
* Density: How much mass is packed into a given volume (a pencil is less dense than a coin).
* Hardness: How resistant they are to scratching or indentation (a coin is harder than a pencil).
* Color: The way they reflect light (a pencil might be black, a coin might be copper-colored, and sugar is white).
* They can undergo changes of state: Depending on the temperature, all three objects can change states. For example, sugar can melt, the metal coin can melt, and the wood of the pencil can be burned.
* They have atoms: All matter, including these objects, is made up of tiny particles called atoms. These atoms are arranged differently in each object, giving them their unique properties.
