Wind Vane

Wind Vane

The wind speed is something that affects us knowing or unknowingly ranging from a wind farm, forest fire and even for weather forecast. Let us find out as to how we could make a wind vane to find wind direction as it would come handy in weather predictions and monitoring.

How To Make A Wind Vane?

Wind wane has two ends, one end is shaped like an arrow and turns to the direction from which the wind blows and the other end is wider and catches the breeze. If the wind wave arrow points to the east then it means that the wind is blowing from the east. Make your own wind wave by following the steps provided here.

Things needed

  • Straw
  • Pin
  • Skewer
  • Marker
  • Scissors
  • Food container lid

Procedure

  1. Sketch a triangle on the container lid with a marker and cut the paper piece out. Afterwards cut out a rectangle from the container lid.
  2. Make an opening at the end of the straw on both sides and attach the triangle on one side and rectangle on the other side.
  3. Insert a pin in the middle of the straw and to the right end of the skewer. Your wind vane is ready to use.
  4. Keep the wind vane in an open area where it is easy to view from the inside so that you could tell the wind direction easily without having to come outside.

What happens next:

To make an accurate prediction of the weather, it would be ideal that you should keep the rain forecast and atmospheric pressure besides the wind speed and direction.

The Projects mentioned above would have shown the bright and interactive side of science which are not yet noticed by people but highly beneficial for students in particular. Implementing such projects in schools and doing them at home would make children interested and fascinated in knowing about science subjects in a better manner over the years to come.

Practise This Question

A boy riding on his bike is going towards east at a speed of 42ms1. At a certain point he produces a sound pulse of frequency 1650 Hz that travels in air at a speed of 334ms1. A second boy stands on the ground 45C south of east from him. Find the frequency of the pulse as received by the second boy.
