  Building a Wind Vane

Background

Wind VaneA wind vane is really just a flat piece of metal or wood on a swivel that catches the wind and points toward and away from the wind. You have probably seen pictures of a wind vane on top of a barn. It is usually shaped like a farm animal such as a horse or a rooster. It usually has an arrow to point in the direction the wind is blowing. However, wind is described in terms of where it is blowing from. For example, a west wind blows east.

Materials

  • 3 ft x 3 ft piece of thin wood or plastic
  • bicycle wheel or skate wheel or lazy susan
  • saw
  • screws
  • plastic or metal letters, N, E, W, S
