Weather Tools What are they? What do they do? Essential Questions What tools do we use in weather? What is a thermometer? What is a wind vane?

What is an anemometer? What is a barometer? Measuring Weather Just like we use a ruler to measure length, there are certain tools we use to measure weather. Because there are many different types of

weather data, there are many instruments used to monitor that data. The Most Common Weather Tools Are: Thermometer Wind Vane Anemometer

Barometer Rain Gauge Thermometer A thermometer is a weather tool used to measure the temperature. We measure temperature in degrees Fahrenheit or

degrees Celsius Water boils at 212 degrees Fahrenheit Water freezes at 32 degrees Fahrenheit Wind Vane By observing wind vanes, we can know

the direction of the wind. Knowing the direction of the wind is an important part in predicting the weather. Anemometer Wind speed is an

important part of weather. An anemometer is a weather tool that measures wind speed. Barometer Barometers are important to

measuring air pressure. Air pressure can help you predict good or bad weather. Rising air pressure often predicts cooler air and less chance of rain. Falling air pressure often predicts precipitation arriving soon and more humidity in

the air. Rain Gauge A rain gauge is a weather tool used to collect rain. Using measurements on the side of the rain gauge, you can see

how many inches it rained. Lets Review A thermometer tells us the speed and direction of wind. A. True B. False

Lets Review Rain gauges tell us how much it rained. A. True B. False Lets Review Which of the following is NOT a weather condition? A. air temperature

B. moisture and precipitation C. time of day D. wind speed and direction Lets Review Extended Response What two weather instruments are most important for predicting the weather? Be able to justify your answer.
