Wind Gauge
How hard is the wind blowing? Find out by making your own simple wind gauge.
What You'll Need:
- String
- Hole puncher
- Safe scissors
- Crepe paper
- Newspaper
- Light cloth
- Heavy cloth
Using string, attach four strips cut to equal sizes -- one each of crepe paper, newspaper, light cloth, and heavy cloth -- to a branch or rain gutter. You'll discover:
- When the wind blows softly, the crepe paper will react.
- When it blows a little harder, the newspaper will flutter.
- As the wind increases in strength, the light cloth will wave.
- When the heavy cloth flaps, you'll know the wind is blowing hard!
The next experiment is an ingenious thermometer that you can make yourself.
