  • True or False: Oven mitts are conductors.
    False
  • What is thermal energy?
    energy that comes from heat
  • If I leave a wooden spoon in a pot of boiling water, what will happen to it?
    It doesn't become hot (wood is an insulator)
  • Why is wood considered an insulator?
    because it stops or slows the transfer of energy from one thing to another

  • If I leave a metal spoon in a pot of boiling water, what will happen to it?
    it will become hot
  • What is a conductor?
    a material that allows energy to transfer through something
