First, you need to know a little about me and how I make my predictions.

• Scientists who studies and measures weather conditions.

Some call me a weatherman but I went to school to learn more and became a ………

• Need to know how to use and read the following instruments:

Thermometer

• measures air temperature

Hot Fact1593 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.

Galileo’s Thermometer

Barometer

• measures pressure

of the atmosphere (air pressure)

Hot Fact- Evangelista Torricelliinvented the mercury barometer in 1644.

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 • finds the wind’s

direction

Hot Facts -The first metal wind vane was a Life-size Greek God, Triton, that was placed in Athens between 48 BC to 250 AD (This vane of Triton represented him traditionally with a human head and upper body and the tail of a fish. He also held a wand in his hand pointing the direction from which the

wind blew.)
