Weather Instruments
This tool measures the amount of rain fall
rain gage
On a weather map, this color often indicates rain
Green
This occurs when water heats up and becomes a gas.
Evaporation
In what direction will warm air move?
Up/Rises
What is a hypothesis?
If...then statement. Relates IV and DV.
A tool to determine wind direction.
Wind vane
Areas of low pressure are shown with this symbol while areas of high pressure are shown with this symbol?
Water vapor cools and becomes a liquid in this process.
Condensation
In what direction will cold air move?
Sinks/down
What is an independent variable?
The thing the person doing the experiment is changing/controlling.
A sling psychrometer measures...
This type of line is often on a map to show areas with a certain value
isoline
Rain and snow are examples of...
precipitation.
Wind blows from _____________ pressure to __________ pressure.
High to low
What is the dependent variable?
The variable that is changed by the independent variable. What is being studied.
Thermometer, degrees C or degrees F
When isolines showing pressure are closer together, what might you find in that area?
Higher windspeeds.
The energy that drives the water cycle comes from?
If there is a greater pressure difference, what will be true about the wind speed?
Wind speed will be greater.
Write a hypothesis to relate how studying might impact your grade on a quiz.
If I study, then I will pass.
This tool measures wind speed. Bonus points if you can spell it without notes!
anemometer
This government organization makes weather maps that we often use in class.
NOAA
What are condensation nuclei?
Tiny particles that condensation occurs on to form clouds.
What are weather conditions like in high pressure systems?
Normally dry, cool, clear sky
A scientist wants to know if giving dogs food or toys will make them happier. What is the independent variable in this experiment and what is the dependent variable in this experiment?
IV: Food or toy
DV: How happy the dogs are.
