Atmosphere & Air Pressure
What the air outside is like at any given time and place.
Weather
When you drink water, it’s...
Liquid
To change from liquid to gas.
Evaporate/Evaporation!
The movement of air.
Wind!
Scientists use these tools such to find wind direction.
Wind Vanes & Wind Socks!
The layer of air that surrounds Earth.

If you put a tray of water in the freezer, it turns to a...
Solid
To change from gas to liquid.
Condense/Condensation!
A large body of air in the atmosphere.
Air Mass!
Warm air masses rise in the atmosphere.
Cool air masses sink.
Measures wind speed. Wind pushes the cups and causes them to spin.
Anemometer!
The weight of air as it presses on objects below or within it.
Air Pressure
If you leave a tray of water out in the hot sun, it evaporates into a...
Gas
Water that falls from the sky in the form of rain, snow, sleet, or hail.
Precipitation
A measure of how fast wind blows.
Wind Speed!
Means over water.
Maritime!
The weather patterns in a place over a long period of time.
Climate
The gas form of water.
Water Vapor
A measure of the amount of water vapor in the air.
Humidity!
The direction from which air moves when wind blows.
Wind Direction!
Means over land.
Continental!
Temperature is a measurement of how hot or cold something is.
Typically, when matter increases in temperature, it begins to spread out. For example, when liquid water is boiled to become water vapor, the tiny particles spread out so much that it becomes hard for anyone to see them.
