Weather Tools 2 nd Grade Weather Unit

Weather changes occur day to day and from season to season.

In order to understand daily weather conditions, weather data must be collected accurately using weather instruments.

Wind Speed the condition of how fast the air is moving

Wind Speed measured with the Beaufort Scale

Beaufort Scale Wind speed Description Visual cues 0 1 mph Calm winds Smoke rises vertically 1 2 mph Light winds Smoke drifts 2 5 mph Light breeze Leaves rustle 3 10 mph Gentle breeze Lighter branches sway 4 15 mph Moderate breeze Dust rises. Branches move 5 21 mph Fresh breeze Small trees sway 6 28 mph Strong breeze Larger branches move 7 35 mph Moderate gale Trees move 8 42 mph Fresh gale Twigs break 9 50 mph Strong gale Branches break 10 59 mph Whole gale Trees fall 11 69 mph Storm Violent blasts 12 75+ mph Hurricane Structures shake

Wind Direction the condition determined by where the wind/moving air is coming from

Wind vane Wind direction is determined with a wind vane (weather vane). Wind direction is described by the direction from which the wind is blowing.

Wind vane How does it work?

Using a Wind Sock

Precipitation The condition of the type of water falling to Earth from the clouds

Rain gauge Amount of precipitation is measured in a rain gauge. Markings on the side show much rain has fallen.

Rain gauge How does it work? Rain falls and collects in the rain gauge. Markings on the side show the amount of rain that has fallen. Measures rainfall in inches.

Temperature The condition of how warm or cold the air is at a given time

Thermometer Air temperature is read using a thermometer. The scale may be read in degrees Fahrenheit or Celsius. Air temperature should be measured out of direct sunlight.
