Weather vane
What is the name
of a simple
device that lets
us know which
way the wind is
blowing?
Weather vanes
• Measure wind speed
(how strong the wind
is)
• Faster it spins, the
stronger the wind!
Older weather vanes
Could only show which way the wind was blowing
Weather vanes for decoration!
A different kind of weather vane
• They call it a “wind
sock”!
• Found at airports
quite often
• Mostly for telling wind
direction
• Can tell if the wind is
strong or weak, but
can not give the exact
speed
Wind socks!
• They are also
used for
decoration, like
weather vanes
Thermometer

Thermometers
