  Scientists use many different kinds of tools. Tools can
make objects appear larger. They can help you measure
volume, temperature, length, distance, and mass. Tools
can help you figure out amounts and analyze your data.
Tools can also help you find the latest scientific information.
  A rain gauge is used
to measure the amount
of rain that has fallen.
  You can look at a wind
sock to see which direction
the wind is blowing.
 
  Wind socks and wind vanes
are examples of wind direction
indicators.
  Meteorologists use
 Doppler radar to
help determine
weather conditions.
 
  You use a thermometer to measure temperature.
Many thermometers have both Fahrenheit and
Celsius scales. However, scientists usually use
only the Celsius scale. In experiments scientists
sometimes use thermometers to help measure
the gain or loss of energy.
