Amazing facts about solids liquids and gases
Solids, Liquids and Gases by Ontario Science CentreSolids, Liquids and Gases has 13 experiments carefully chosen by the Ontario Science Centre. With minimal supervision, children can explore the three states of matter, what makes each state unique and how matter changes from a solid to a liquid to a gas through evaporation, condensation, melting and freezing. Filled with bright photographs, the Starting with Science series provides valuable lessons about basic science for five to eight year olds.

Solids are one of the three states of matter and, unlike liquids or gases, they have a definite shape that is not easy to change. Most solids are made up of tiny crystals. Solids behave as they do because of the way their particles are arranged. The particles of a solid are linked by strong forces, which pull the particles tightly together. So, although the particles can vibrate, they cannot move about easily. This arrangement explains why solids usually keep their shape and feel firm.
Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter. Before we look at why things are called solids, liquids or gases, we need to know more about matter. Matter can be a confusing word because it has several meanings. Scientists have a different meaning for matter — matter is anything that occupies space and has mass. Matter is made up of tiny particles.
