  1. WeatherTools What are they? What do they do?

  2. Directions • 1. Glue the weather instrument sheet into your notebook. DO NOT GLUE IN THE SHEET WITH ALL THE PICTURES • 2. Go through the slides to find out what each weather instrument is used for. • 3. As you go through the slides, fill in the information for each instrument and cut/paste the correct picture onto your sheet that matches the correct instrument • 4. Watch the weather instrument video and take the quiz using the link on slide 12. • 5. Work on your weather study guide or the weather review puzzle. The puzzle does not get glued in your notebook.

  3. The Most Common Weather Tools Are: • Thermometer • Wind Vane • Anemometer • Barometer • Rain Gauge

  4. Thermometer • A thermometer is a weather tool used to measure the temperature. • Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is.

  5. Weather Balloon • Weather balloons are sent into the atmosphere to gather information about air pressure, temperature, humidity and wind speed at higher altitudes.

  6. 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.

  7. Anemometer • Wind speed is an important part of weather. • An anemometer is a weather tool that measures wind speed. • The cups catch the wind, turning a dial attached to the instrument. The dial shows the wind speed.

  8. Barometer • Barometers are important to measuring air pressure. Air pressure can help you predict good or bad weather. • A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions. An Italian scientist named Torricelli built the first barometer in 1643.

  9. Wind Sock • These are used to measure wind direction and relative speed (but not exact speed). They are used a lot at airports and chemical plants.

  10. 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.

  11. Hygrometer • A hygrometer measures how much moisture is in the air (humidity).
