"Anemometer" is a fancy name for wind speed gauge, something you can make as an easy science activity for kids. Measure the wind's strength, and make a pretty outdoor decoration at the same time.

What You'll Need:

  • Hole punch
  • Plastic lid from a 39-ounce coffee can
  • Blunt scissors
  • Clean plastic egg carton
  • Stapler and staples
  • Yarn
  • 3/8-inch wooden dowel
  • Electrician's tape
  • Clean foam food tray (from fruits and vegetables only)

Step 1: Punch a hole in the center of the plastic lid that is large enough to fit the wooden dowel.

Step 2: Cut out four cups from an empty egg carton. Staple the cups to the lid as shown in the illustration.

Step 3: Cut 12 strips of yarn, each 6 inches long, and staple three of the pieces of yarn behind each cup.

Step 4: Roll a 4-inch piece of tape around the dowel about 2 inches from the end.

Step 5: To make the washer below the lid, cut a 1-inch circle from the foam food tray. Cut a small hole in the center of the washer that is large enough to fit through the dowel.

Step 6: Place the dowel through the center hole on the plastic lid. The lid should be just below the tape.

Step 7: Place the washer on the dowel under the plastic lid.

Step 8: Wrap another 4-inch piece of tape around the dowel under the washer.

Step 9: Stick the dowel in the ground outside your house in a windy place, and watch the anemometer turn.
