Weather vane
What is the name of a simple device that lets us know which way the wind is blowing?

Weather vanes
• Measure wind speed (how strong the wind is)
• Faster it spins, the stronger the wind!

Older weather vanes
Could only show which way the wind was blowing

Weather vanes for decoration!

A different kind of weather vane
• They call it a “wind sock”!
• Found at airports quite often
• Mostly for telling wind direction
• Can tell if the wind is strong or weak, but can not give the exact speed

Wind socks!
• They are also used for decoration, like weather vanes

Thermometer
What is the name of the device that is used to measure temperature?
![Page 9: Weather Instruments – measuring rain, wind, and the temperature! By: Matt Hoffman 2 nd grade Accawmacke Elementary](https://reader031.vdocuments.net/reader031/viewer/2022012916/56649d985503460f94a83294/html5/thumbnails/9.jpg)
Thermometer
• Measures temperature
• Degrees Fahrenheit (32-212)
• Degrees Celcius (0-100)

Thermometers
• Colored alcohol in them
• Rises when it heats up, goes down when it gets cold
![Page 11: Weather Instruments – measuring rain, wind, and the temperature! By: Matt Hoffman 2 nd grade Accawmacke Elementary](https://reader031.vdocuments.net/reader031/viewer/2022012916/56649d985503460f94a83294/html5/thumbnails/11.jpg)
Different than thermometers doctors use…
• Both measure temperature!
• Their thermometer is much more sensitive

Worlds tallest thermometer!
• 134 feet high
• In southern California – the hottest temp. it ever measured was 134 degrees!

Rain gauge
• Measures how much rain fell
• Like a ruler attached to a big, clear cup!
• Can tell if it may flood soon
• Farmers need to know how the soil is (too wet or too dry)
![Page 14: Weather Instruments – measuring rain, wind, and the temperature! By: Matt Hoffman 2 nd grade Accawmacke Elementary](https://reader031.vdocuments.net/reader031/viewer/2022012916/56649d985503460f94a83294/html5/thumbnails/14.jpg)
What the rain gauge is for…
• Can tell if it may flood soon
• Farmers need to know how the soil is (too wet or too dry)
• People need to know when to water their plants
• Too much rain causes erosion

Weather balloon
What is the name of the device that is sent high into the atmosphere to measure temperature, wind speed, air pressure, and other things?

Weather Instrumentsand what they measure
• Weather vane – wind speed and direction• Wind sock – wind direction• Thermometer – air temperature• Rain Gauge – amount of rain that fell
