4th Grade

Thermometer

• Used to measure temperature.

• Temperature is measured in Fahrenheit or Celsius.

• Low Temperature = Cold Weather

• High Temperature = Hot weather

Multiple Choice

Which answer choice correctly describes the job of a thermometer?

• A device that tells how much rain has fallen.

• A device that tells how much snow has fallen.

• A device that is used to measure temperature.

• A device that shows you how fast you are going in a car.

Rain Gauge

• A tool that is used to measure the amount of rain that has fallen.

• It looks like a transparent cylinder with markings.

Multiple Choice

Which answer choice correctly describes the job of a rain gauge?

• A weather tool that tells the direction of the wind.

• A weather tool that measures the speed of the wind.

• A weather tool that tells how hot or cold something is.

• A weather tool that measures how much rain has fallen.

Wind Vane

• A tool that tells the direction of the wind.

• Sometimes called a "weather vane."

• Wind direction is measured in N, NE, E, SE, S, SW, W, or NW.

• A "wind sock" can be used to measure wind direction also, but it does not have the directions marked on it.

Multiple Choice

Which answer choice correctly describes the job of the wind vane?

• A tool that is used to measure wind direction.

• A tool that is used to measure wind speed.

• A tool that is used to measure how hot or cold something is.

• A tool that is used to measure air pressure.

Multiple Choice

What is another name for the wind vane?

• Weather instrument

• Weather sock

• Weather vane

• Anemometer

Anemometer

• A weather tool that measures wind speed.

• As wind speed increases, the cups will spin faster and the speed of the wind will be read digitally.

• Wind speed is measured in "miles per hour" (mph).

Multiple Choice

Which statement DOES NOT describe an anemometer?

• A tool that is used to measure wind speed.

• Measures wind speed in mph.

• A tool that is used to measure wind direction.

• The cups on an anemometer will move faster with stronger winds.

Barometer

• A tool for measuring atmospheric pressure.

• Atmospheric pressure, or air pressure, is the weight of the air.

• Higher pressure = clear, dry, and sunny skies (This has NOTHING to do with temperature!)

• Lower pressure = cloudy skies with a chance of precipitation

Multiple Choice

Which of the following information could you get from a barometer?

• Temperature

• Chance of rain or not.

• How much rain has fallen.

• The direction of the wind.
