How do we measure the weather?

2. MEASURING AIR PRESSURE
Air pressure is the pressing by the air, or the strength of the air
A barometer measures the air pressure
Low air pressure means stormy or bad weather
High air pressure means sunny and good weather

3. BAROMETER

4. MEASURING TEMPERATURE
Temperature is the measure of how hot or cold something is
Temperature is measured with a
THERMOMETER

5. THERMOMETER
A thermometer measures temperature in Degrees Celsius and Degrees Fahrenheit

6. MEASURING PRECIPITATION
Precipitation is any kind of water that falls from the sky: rain, snow, sleet or hail
Precipitation is measured with a
RAIN GAUGE OR
SNOWBOARD

7. RAIN GAUGE

8. SNOWBOARD
Like long rulers that people stick into the snow to see how high it is.

9. MEASURING WIND Wind is the movement of air. Wind is measured with a
WEATHER VANE
and a
ANEMOMETER

10. WEATHER VANE
Shows Wind Direction

11. ANEMOMETER Measures Wind Speed
Watch the red cup. Count how many times the red one goes around in 1 min.
Divide this number by 10. Your answer is the MPH of wind.

12. WIND SPEED
Wind speed can also be estimated with a Wind Scale that shows the movements of objects around you.

13. This is one example of a wind scale.

14. HOMEWORK: MAKE YOUR OWN WIND SCALE
IN THE BOXES PROVIDED SHOW THE BIGGEST OBJECT THAT COULD BLOW GIVEN A CERTAIN SPEED OF WIND.
