We made this super simple wind vane for school this week.
- straight pin
- pencil with an eraser
- index card
- celophane tape
- First cut a triangle out of the index card to serve as the arrow head. Then cut a tail from the index card. The tail is just a large rectangle with a triangle shaped notch cut out of one side.
- Tape your head and tail to the straw to create the arrow.
- Then push the pin through the straw and into the eraser of the pencil. Swivel the arrow back and forth a few times to loosen it up so it will turn in the wind.
- Talk about how wind direction can give you a clue as to what weather is coming. For example if you live on the west coast and the wind is coming from the west, then you’ll probably get rain.
- Talk about shapes. Basic triangle and rectangle for little kids and for older kids discuss isosceles triangles, lengths and widths of rectangles, and area.
- Wind direction near the ground can be different from wind direction above the buildings because buildings and trees can deflect the wind, making it swirl.
- Try this Wind Detector Activity as well.
