o I can explain that air surrounds us, takes up space, and moves
around us as wind.

Air is made up of matter
Air is a mixture of gases
Life on earth depends on gases in the air
Air temperature is measured with a thermometer
 Textbook pages E10-13 and E38-39
o I can explain that air around us can be measured using barometric
pressure.

Important Information
Pressing down of air on the earth is air pressure
The higher above you are in the atmosphere, the less air is above you
Air temperature affects air pressure
Rising air pressure usually means drier air and fair weather
Falling air pressure usually means moister air is coming – wet weather
Barometer measures air pressure
o I can identify that water exists in the air as vapor in the form of
clouds and fog.
o I can describe the type of weather brought upon by each cloud type
(cumulus, cumulonimbus, cirrus, and stratus clouds).
Important Vocabulary
Clouds
Fog
water vapor
condensation
Important Information
 Cirrus clouds – Wispy and see-through – Bring fair weather and a change in
weather
 Cumulus clouds – puffy, like cotton balls – Bring fair, sunny weather
 Stratus clouds – gray layered – Bring drizzle or rain, if near ground called fog
 Cumulonimbus – large, mushroom-like – bring thunderstorms, rain, snow and
hail
 When water evaporates into water vapor, it condenses into a cloud
 Textbook pages E54-57
o I can identify the forms of precipitation (rain, snow, and hail).
o I can describe how water changes from one state to another
(freezing, melting, condensation, and evaporation).
Important Vocabulary
Rain
Snow
Hail
rain gauge
evaporation
condensation
precipitation
water cycle


Water changing from a liquid to a gas is evaporation
Water vapor changing back from a gas to a liquid is condensation
Water or snow falling from clouds is precipitation
Heat from the sun warms water on the earth, which changes into water vapor through
evaporation. When water vapor cools it condenses into clouds. When clouds become too
heavy, precipitation falls back to earth. This is the water cycle.
 Rain is measured with a rain gauge
 Textbook pages E46-48
o I can describe the weather using the following information:
temperature, wind direction, wind speed, precipitation, and
barometric pressure
o I can describe weather changes over a period of time.
o I can record and explain weather data from an investigation.
Important Information
 These I can statements connect to the daily weather data students
recorded in the classroom.
o I can record local weather information on a calendar or map using
weather symbols.
o I can recognize that weather generally moves from west to east
across the United States.
o I can analyze weather data to make an inference about what will
most likely occur next.
Important Vocabulary
Warm front
wind
Cold front
weather map
Important Information
 Meteorologists make and study weather maps
 Meteorologists forecast the weather by looking at weather instruments and
weather data
 Winds mover over large parts of the earth’s surface – moving weather
systems
 Weather usually moves across the country from west to east.
 To get a clue about your weather tomorrow, look at the weather to the west of
where you live!
 Meteorologists use weather symbols on a map to show different types of
weather
 Textbook pages E58-63
o I can describe the proper use and placement of scientific tools.
Important Vocabulary
Thermometer
Barometer
Wind Vane
Anemometer
Rain Gauge
Beaufort Scale
Important Information
 Thermometer measures air temperature.
 For accurate measure a thermometer should be placed in the shade because
in direct sunlight the thermometer heats up and makes the reading too high.
 Barometer measures air pressure.
 For accurate measurement a barometer can be place inside or outside.
 Wind vane records wind direction
 For accurate measurement a wind vane should be placed up high or on the
roof of a house/building
 Anemometer measures wind speed
 For accurate measurement an anemometer should be placed up high with a
wind vane.
 Rain gauge measures the amount of rain fall
 For accurate measurement a rain gauge should be placed out in the open to
collect the amount of rain falling.
 Beaufort scale is a scale that measures wind speed using 12 different
categories. You can use the Beaufort scale when you don’t have an
anemometer.
