Making an Anemometer

Start Making an Anemometer

Procedural Steps

  1. Select an age appropriate category – Grades K-5; Middle School; High School; Undergraduate School; Citizen Science
  2. Select a product category – Electronic; Non-Electronic  **Note – Non-Electronic means that the measuring device is not electronic.  It is understood that a timer or video camera may be required to calculate data.
  3. Visit the GLOBE Program and learn about Wind 
  4. Visit the AREN Project to learn about the role of kites and safety requirements when flying kites. 
  5. Construct a low-cost (less than $30) for measuring wind speed.  **Please note, wind speed should be determined at 1.5 meters above ground level.  Comparison to a known wind speed measurement tool may help support your conclusions on your tools measurements precision and accuracy. Not all schools can afford commercial electronic wind gauges and electronic anemometers, so the construction of a low-cost device is vital to having more schools participate in collecting wind speed measurements.
  6. Accuracy and Force Range – Please keep in mind that GLOBE emphasizes accuracy in measurements and that units are standard throughout the world.  The range should complement the Beaufort Force Scale:

 

Force

km/h

Description

0

<1

Calm, smoke rises vertically

1

1 – 5

Direction of smoke shown by drift, wind vanes don’t move

2

6 - 11

Wind felt on face, leaves rustle, wind vanes move

3

12 – 19

Leaves and small twigs in constant motion, light flags extended

4

20 – 28

Raises dust and loose paper, small branches move

5

29 – 38

Small trees with leaves sway, crested wavelets on inland waters
