To teach Year 4 pupils primary school on weather instruments used to measure weather.

1. WEATHER INSTRUMENTS
What are they used for?

2. WEATHER INSTRUMENTS

3. The weather instruments are always be used:
• Anemometer
• Barometer
• Windsock
• Weather balloon
• Hygrometer
• Wind vane
• Rain gauge
• Thermometer

4. ANEMOMETER
• A device used for measuring wind speed.

5. BAROMETER
• A scientific instrument used to
measure atmospheric or air
pressure.

6. RAIN GAUGE
• A rain gauge is an instrument used
by meteorologists and hydrologists t
o measure precipitation (e.g. rain) in
a certain amount of time.

7. THERMOMETER
• A device that
measures temperature or temperature
gradient using a variety of different
principles.

8. WIND VANE
• An instrument for showing the
direction of the wind .

9. WINDSOCK
• Designed to indicate wind direction and relative
wind speed. Windsocks typically are used
at airports and at chemical plants where there is
risk of gaseous leakage. They are sometimes
located alongside highways at windy locations.

10. HYGROMETER
• An instrument used for measuring the moisture
content in the environment. Humidity measurement
instruments usually rely on measurements of some
other quantity such as temperature, pressure, mass
or a mechanical or electrical change in a substance
as moisture is absorbed.

11. WEATHER BALLOON
• A balloon (specifically a type of high altitude
balloon) which carries instruments aloft to send
back information on atmospheric
pressure, temperature, humidity and wind speed by
means of a small, expendable measuring device
called aradiosonde.
