THERMOMETER

• Measures air temperature.
• Most thermometers are closed glass tubes
  containing liquids such as alcohol or mercury.
• When air around the tube heats the liquid, the
  liquid expands and moves up the tube.
• A scale then shows what the actual temperature
  is.

• It tells you whether or not the pressure is
  rising or falling.
• A rising barometer means sunny and dry conditions

Compass

• A COMPASS is a navigational instrument for
  finding directions.

• Then meteorologists compile and analyze the data
  with the help of computers.
