  1. Solids, Liquids and Gases March 2006

  2. By the end of this lesson you will know: • what a ‘material’ is • what we mean by ‘property’ • what the properties of solids, liquids and gases are

  3. Materials • Everything is made from some sort of ‘material’ • Materials are made up of lots and lots of tiny pieces • These tiny pieces are known as particles • Solids, liquids and gases are all made of lots of particles

  4. Properties • The property of a material tells us something about what it is like… • Materials may be hard, soft, shiny, rough • Can you think of any more?

  5. Solids • A solid is something that we can hold on to • A solid keeps its shape, unless we cut it or shape it ourselves • In a solid, all of the particles are packed together very tightly

  6. Liquids • Liquids are runny • They can be poured • The particles are less tightly packed, so they can move about • If poured from one container to another, they will take the shape of their new container

  7. Gases • The particles in gases have lots of room to move • Gases are all around us • They spread into all of the empty places they can • Most are invisible

  8. An example – water • Water can be a solid, a liquid or a gas • When it is cold it is solid – ICE • When it is at room temperature it is a liquid – WATER • When it is hot it is a gas – STEAM

  9. Your turn!! • Having learned about the properties of solids, liquids and gases I’ like you make a list of all of those you know about already
