Aim: To compare the resistance of different types of wood to termite attack

Materials: gloss paint, used motor oil, creosote, 4 samples of softwood (pine), 4 samples of hardwood (teak/eucalyptus)

Method

  1. Coat one piece of each wood with used motor oil
  2. Paint one piece of each piece of wood with gloss enamel
  3. Paint one piece of each wood with creosote
  4. Place a bare piece of wood and the other ones above near a termite hill during dry weather
