Try it! How do you measure the speed of the wind?

Sometimes strong, sometimes soft, the wind blows in different directions and strengths. Today’s experiment, the kids will learn to make an anemometer – a device to measure wind speed. See if they could make a weather forecast from it too!

What you'll need:

  • A white plastic bottle
  • A wooden kebab skewer
  • A Straw
  • A pencil
  • A marker pen
  • Scissors 
  • Some sticky tape

In 6 easy steps construct an Anemometer:

  1. Cut a ring from the plastic bottle and split it in half
  2. Turn over one of the halves and attach the skewer down the middle.
  3. Make a hole in the middle of the bottle top, push the skewer through it and screw the top back on the bottle
  4. Draw 3 lines of dots on the bottle – 1 dot near the bottle top, 4 dots in the 2nd line and 8 dots along the edge
  5. Slip the skewer into the straw
  6. Hold the anemometer by the straw lightly to let it catch the wind.
