Anemometer

According to Wikipedia, an anemometer is a device that is used for measuring wind speed, and is one instrument used in a weather station. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti in around 1450. It's tremendously beneficial to anyone wanting to introduce middle school and high school students to measuring velocity and wind pressure. This anemometer is constructed out of corrosion resistant material, making it suitable for outside use. You can use it to determine wind speed by counting rotations. One cup on this unit is colored red to facilitate in counting the number of rotations. Instructions are included to aide in learning about specific scientific principles (including convection, the Coriolis effect, and friction). Highly recommended for use in the science classroom, as an addition to a science fair project on weather patterns, or for the science fan wanting to have on at hand in their backyard!
