Materials

This unit examines the varying properties of elements, the reactivity series, and the role of carbon in metal extraction. It also explores catalysts and the properties of ceramics, polymers, and composites. Emphasis is placed on evaluating risks, using appropriate techniques, and interpreting data.

Prior knowledge

  • Metals are good conductors of heat and electricity, they are strong, shiny, malleable and ductile.
  • Non-metals are normally poor conductors of heat and electricity, they are not strong, and are dull and brittle.
  • Graphite is a non-metal that is an electrical conductor.
  • When a metal reacts with acid bubbles may form, the temperature rises and the metal reduces in size or disappears.
  • Not all metals react with an acid.
  • The word equation for a metal and acid reaction is: metal + acid ⭢ salt + hydrogen.

Source curriculum references

  • Evaluate risks
  • Ask questions and develop a line of enquiry based on observations of the real world, alongside prior knowledge and experience
  • Use appropriate techniques, apparatus, and materials during fieldwork and laboratory work, paying attention to health and safety
  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
  • What catalysts do
  • The varying physical and chemical properties of different elements
  • The order of metals and carbon in the reactivity series
  • The use of carbon in obtaining metals from metal oxides
  • Properties of ceramics, polymers and composites (qualitative)
