Wind Direction with Sail Boats

We have been finding out about wind direction and force.  There are some very clever children in room 10.  They know that wind can blow from the North, South, East and West and anywhere in between!  We made sail boats to test if we could guess wind direction.  One person created the wind through a straw, and the rest of the group had to make a thinking guess about which direction the wind was blowing from.  It was lots of fun!
