A wind vane tells you which way the wind is blowing

1
Im going to show you how to make a wind vane!
What does a wind vane do?
A wind vane tells you which way the wind is
blowing
2
First you need two pieces of card. Out of one
you cut an arrow shape. Use your scissors
carefully!
3
Draw round your arrow on the other piece of
card. Now cut out the second arrow with scissors.
4
Now you need an empty plastic bottle with a hole
in the lid. You also need some glue, a straw and
some masking tape.
5
Tape the straw to the arrow. Make sure the arrow
balances on the straw like a seesaw. This is the
hardest part! Then glue the two arrows together
so they sandwich the straw.
6
Put some water in the bottle to stop it blowing
over. Then push the end of the straw through the
hole in the lid. Stick four pieces of masking
tape on the bottle marked with N, E, S and W.
7
Take the wind vane outside and use a compass to
make sure it is set up in the right direction.
The arrow will point to where the wind is coming
from!

Here, the wind is coming from the south. You can
record the class results on this chart which is
called a Wind Rose.
