Before You Start...
A Weather Vane is also called a "Wind Vane".
It is a tool for measuring wind direction. It spins in the air atop a rod
or a pole, and points in the direction from which the wind comes.
The Weather Vane is one of the oldest weather tools known. The part of the
vane that turns into the wind is usually shaped like an arrow. The other
end is usually very wide, so that it will catch even the smallest breeze.
The breeze turns the Weather Vane until it catches both the "wide end"
side and the "narrow (arrow) end" side of the Weather Vane equally.
The arrow ALWAYS points into the wind. The arrow tells you the direction
from which the wind is coming.
