What you'll needA large piece of construction paper
What to doDecorate a large piece of construction paper with markers, paints or other art materials. Then roll it into a long tube (about the size of a paper towel tube) and tape the paper along the edge, fastening it together like a cylinder.
Once the paper is securely fastened, tape pieces of crepe paper or ribbons around one of the round ends to make streamers that will blow in the wind. You have just created a wind vane.
To complete the project, punch a hole on either side of the top end of the cylinder (the non-streamer end). Take some string, the length is up to you, and tie one end through each hole. You can then take your wind vane outside to see how hard the wind is blowing and from which direction.
