Wind comes in several strengths. In 1805, a British Admiral, Sir Francis Beaufort, developed an observation scale for measuring the winds at sea. The Beaufort scale measured winds by observing their effects on sailing ships and the water's waves. Beaufort's scale was later adapted for use on land also. The Beaufort wind scale is still used today.
Meteorologists use a man-made instrument, an anemometer, to measure wind speed.
An anemometer rotates at the same speed as the wind blows. It is a useful instrument because it gives a true measure of speed to the wind. These activities involve classroom work as well as limited fieldwork. The time frames will vary according to normal classroom variables. These procedure steps are relatively sequential and should be arranged according to classroom teacher preference.
