Weather vanes are used to tell the direction that the wind is coming from. They are most seen on farms, but anyone can own a weather vane. If you or your children are interested in learning more about a weather vane and how it works, you can take the time to make a simple one.
Use your pencil to draw the head of an arrow and the tail of an arrow on a sheet of construction paper. The head should just be a triangle and the tail can look anyway you want it to.
Cut the pieces you just drew out.
Tape the head of the arrow to one end of the straw and the tail of the arrow to the other end of the straw.
Get your pencil and turn it upside down so that the eraser is sticking up and the pencil point is facing down.
Lay your straw over the pencil's eraser so that the eraser is in the middle. Push your pin through the top of the straw and in to the eraser.
Push the pencil point in to the ground outside. A garden is a nice place to put it.
Use a stick to draw in the dirt next to the weather vane. Draw an N in the direction of North, an S in the direction of South, a W in the direction of West, and an E in the direction of East. Your parents may need to let you know which direction is which.
Determine the direction of the wind by glancing at which direction the arrow is pointing.
Make a chart and write down which direction the wind is moving each morning and evening for two weeks.
