This document discusses three instruments used to measure wind and pressure: an anemometer measures wind speed by how fast its cups spin, a weather vane measures wind direction by pointing the direction the wind is blowing with an arrow, and a barometer measures air pressure against a standard.

3. Instruments used to measure
”Wind and Pressure”
1)Anemometer
A device used to measure wind speed .
The cups spin faster as the wind blow faster

It is used to measure wind direction . It ‘s a
movable arrow that points in the direction
