Meteorologist

• Scientists who studies and measures weather
  conditions.

  instruments

Thermometer

• measures air temperature

Galileos Thermometer
Hot Fact 1593 Galileo Galilei invented the
1st Thermometer (on the left). Then in 1714
Gabriel Fahrenheit invented the 1st mercury
thermometer with a F scale. In 1743 Andrus
Celsius created a thermometer with the Celsius
scale.
6
Barometer

• of the atmosphere (air pressure)

Hot Fact- Evangelista Torricelli invented the
mercury barometer in 1644.
7
Anemometer

• measures wind speed

Hot Fact- Measures wind in revolutions per
minute. Aircraft crews need to know the speed of
the wind before taking off and landing.

Weather Vane or Windsock

• Hot Facts -The first metal wind vane was a
