Lesson Title: Today we are learning about
What type of material should we use?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Particles in a solid are arranged in a lattice (pattern).
  2. Different types of solid are have their particles arranged in a differnet shaped lattices (patterns).
  3. Metals are malleable and ductile because their particles are arranged in layers with weakish bonds between them. (This is an oversimplification as dislocations and grain boundaries are the true weaknesses)
  4. When a force is applied to the metal layers they slide over each other changing the material's shape.
  5. Metals are tough because when there is a shock of energy, it can be absorbed in the flexibility of these weak bonds.
  6. Ceramics are brittle because when there is a shock of energy, it can not be absorbed as there is no flexibility in the strong bonds.
  7. Ceramics are hard and brittle because their particles are held in a lattice shape such as a tetrahedral.
  8. Tetrahedrals are strong shapes as each particle is held in place by triangles of bonds.
  9. The strong structure means that particles will not move as much as others so can scratch the softer material. But it also means that a shock of energy can not be absorbed by the bonds as there is no flexibility in the structure.
  10. The particles in polymers are a arranged in chains.
  11. The bonds in the chain are very strong, but the force between chains are relatively weak.
  12. The length of the particle chain affects how the chains interact with each other and so the properties of the polymer.
  13. Application of ceramics, polymers and composites (qualitative)

AFL/Key Questions:
  1. How are particles in a solid arranged?
    Particels in a solid are tightly packed, usually in a regular pattern.
  2. Do all solids have the particles arranged in the same pattern?
    No, different types of solids have their particles arranged in a differnet shaped lattices (patterns).
  3. Why are metals malleable and ductile?
    Metals are malleable and ductile because their particles are arranged in layers with weak bonds between them.
  4. What happens to the metals layers when a force is applied?
    When a force is applied to the metal layers they slide over each other changing the material's shape.
  5. Why are metals known as tough?
    Metals are tough because when there is a shock of energy, it can be absorbed in the flexibility of these weak bonds.
  6. Why are ceramics brittle?
    Ceramics are brittle because when there is a shock of energy, it can not be absorbed as there is no flexibility in the strong bonds.
  7. Why are ceramics hard and brittle?
    Ceramics are hard and brittle because their particles are held in a lattice shape such as a tetrahedral.
  8. Why are tetrahedrals strong shapes?
    Tetrahedrals are strong shapes as each particle is held in place by triangles of bonds.
  9. What does a strong structure mean?
    The strong structure means that particles will not move as much as others so can scratch the softer material. But it also means that a shock of energy can not be absorbed by the bonds as there is no flexibility in the structure.
  10. How are particels in a polymer arranged?
    The particles in polymers are a arranged in chains.
  11. What are the bonds in a polymer like?
    The bonds in the chain are very strong, but the force between chains are relatively weak.
  12. What does the length of a polymer chain affect?
    The length of the particle chain affects how the chains interact with each other and so the properties of the polymer.
  13. What are the applications of ceramics, polymers and composites?
    Ceramics are used in bricks and pottery. Polymers are used in PVC, Lycra,Nylon and polyethene. Composites: waterproof clothing eg; Gore Tex Car wheels.
