  1. Examine each element taking note of its colour, malleability. Use sand paper to clean the materials before looking at them
  2. Set up a circuit as shown in the diagram above
  3. Test the conductivity of each material

Observation/Results

  • The metals are shiny/Have a lustre after they are cleaned
  • The non metals are dull in appearance
  • The metals conduct heat and electricity well
