# Classifying Matter

TermDefinitionExample
Mass The amount of matter in something; measured in grams An elephant has more of this than a mouse. You can measure this using a scale or balance.
Physical Properties Measureable characteristics that describe the physical state of something, including mass, magnetism, temperature, density, shape, solubility, volume and conductivity This is how you can tell types of matter apart. What does it look like? What does it feel like? What is its mass? What is its state?
Magnetism The property of attraction to a magnet I can be tested using a certain type of metal to which other metals, usually containing iron, are attracted.
Physical State The classification of matter as a solid, liquid or gas Examples of the three main include an apple, apple juice and what the leaves of the apple tree give off during photosynthesis.
Relative Density How dense something is compared with a reference material. A boat will float on water because of the air inside. A chunk of granite rock will not float in water. This explains why.
Solubility Measurement of the ability of a solid to dissolve in a liquid An example is when sugar is mixed in water
Thermal Energy Energy that can be measured by a thermometer Rub your hands together quickly, and you will feel this kind of energy. It can be measured with a thermometer.
Conductor Material that allows heat or electrical energy to easily flow through it. Usually these are metal objects. Without these, electrical energy cannot flow from one place to another.
Insulator Material through which heat or electricity does not flow easily. These are typically not made of metal and protect us from the flow of energy in a conductor. Think about a jacket.
Volume The amount of space something takes up. I am the space inside a 3D object.
Matter Anything that has mass and takes up space I am what everything is made from - solid, liquid and gas. Even air, which you cannot see, has me!
