A poster showing the States of Matter.
What is matter?
Matter is anything that has mass and takes up space. It has properties which can be measured, such as mass, volume, density and colour, as well as qualitative properties such as taste and smell. The three common states of matter are solids, liquids and gases.
Solid – A solid is matter that has definite size and shape.
Liquid – A liquid is matter that takes the shape of any container.
Gas – Gas is matter that has no definite shape. Gases take on the shape of whatever container they are in.
States of Water – Water is a great example of the three states of matter. At room temperature, it is a liquid. When it’s frozen it becomes a solid in the form of ice. When it’s heated to boiling point it turns to gas in the form of steam.
