Measure wind speed with this simple, homemade anemometer (say an-uh-MOM-uh-ter).
Make an Anemometer Science Project
What you need:
What to do:
- Color the outside of one cup.
- Cross the cardboard strips to form a plus sign. Staple them together.
- Staple the cups to the ends of the plus sign, making sure they're all
facing the same way.
- Stick the pushpin through the exact middle of the plus sign into the
eraser of the pencil.
- Stick the pointy side of the pencil in to the clay and mound it up so
your anemometer can stand.
- Make sure your anemometer spins freely. If not, you may need to adjust
it a bit.
- Take it outside and set it down in an open area.
- Using the stopwatch, count how many times the colored cup goes around in
You measured the wind's speed in turns (or revolutions) per minute (RPM).
Weather services use anemometers to measure wind, but they convert the RPMs into
miles per hour to tell us how windy it will be. To be considered a good wind
resource to produce wind power, the wind speeds need to be at least 13 miles per
hour, on average. Use your anemometer to measure wind speeds at a different
times of day over several days. According to your anemometer, is wind a good
resource where you live?
