Transcript and Presenter's Notes

Title: Mrs. Bright


1
(6-4.5)
  • Mrs. Bright
  • BRMS
  • 6th Grade Science

2
6-4.5
  • Use appropriate instruments and tools to collect
    weather data (including wind speed, and
    direction, air temperature, humidity, and air
    pressure).

3
What Is Weather?
  • Weather refers to the conditions of the
    atmosphere at a certain place and time.
  • Climate deals with long-term conditions
    in the atmospherepatterns, averages, and
    extremes (most/maximum and least/ minimum).

4
We Cant See Air, So What Can We Measure?
  • Temperature
  • Pressure
  • Wind direction and speed
  • MoistureHumidity and Dew Point
  • Cloudscoverage and type
  • Precipitationtype and amount

5
The Most Common Weather Tools Are
  • Thermometer
  • Wind Vane
  • Wind Sock
  • Anemometer
  • Barometer
  • Rain Gauge
  • Sling Psychrometer
  • Hygrometer

6
Thermometer
  • Used to measure air temperature in degrees
    Fahrenheit or Celsius. Temperature is a measure
    of how much heat energy the air molecules possess

7
Wind Vane
  • Measures wind direction
  • Tells the direction from which the wind is
    blowing.

8
Wind Sock
Tells the direction the wind is blowing. Used at
airports.
9
Anemometer
  • Measures wind speed in miles per hour

10
Barometer
  • Measures air pressure in inches of mercury or
    millibars (mb)
  • Air molecules push down on objectsincluding
    youwith a force that we call the barometric
    pressure.

11
Rain Gauge
  • Measures amount of precipitation in inches or
    centimeters
  • Rain is easy to measureall you need is an open
    tube with a rulera RAIN GAUGE.

12
Sling-Psychrometer
  • Measures relative humidity using a wet dry
    thermometer.
  • Temperature readings are converted by using a
    relative humidity table.

13
Hygrometer
  • It too measures humidity.
