WEATHER
Weather is hot,
Weather is cold,
Weather is changing
As the weeks unfold.
It is raining,
It is snowing,
It is windy
With breezes blowing.
Skies are cloudy,
Skies are fair,
Skies are changing
In the air.
Days are foggy,
Days are clear,
Weather is changing
Throughout the year!

What is WEATHER ?
Weather…
• Tells how the air moves (wind) and describes
anything it might be carrying such as rain,
snow or clouds.
• Thunder, lightning, rainbows, fog and other
special events are all part of weather
• describes the condition of the air at a
particular time and place - the temperature
and rainfall
What are the Building Blocks of Weather?
Clouds
Precipitation
Wind
Video: Water Vapor, Clouds, Dew and Frost
What is Precipitation?
Forms of Precipitation
Weather Condition
• Rain or drops of liquid water fall from
• Rain
the clouds when water vapor
condenses around dust particles in the
clouds, forming tiny droplets that
eventually get too big for the cloud to
hold so they fall down.
• Snow
• Hail
• Snow form in clouds where the
temperature is below freezing as ice
crystals or groups of many ice crystals
called snowflakes.
• Hail forms within thunderstorm clouds
when upward moving air keeps pellets
of frozen water from falling. The pellets
grow larger as drops of very cold water
hit them and freeze
What is Wind ?
Wind
Whoosh! Whoosh!
Whoosh!
Feel the wind push!
Blow! Blow! Blow!
Where’s my hat go?
Answer: Moving Air
What are some objects that wind can move?
Explore: What can we observe about
the wind and how it moves things as
we walk in our schoolyard?
1. Label a page in your science notebook:
Evidence of Wind
2. Draw pictures of things and label them that can be
moved by the wind.
3. Share with your group.
4. What evidence of wind did we see in the schoolyard?
5. Describe the way these objects moved in the wind?
6. What were some objects that did not move in the
wind? Why didn’t they move?

Severe Weather
Thunder and Lightning
(sung to “Pop Goes the Weasel”)
When a storm begins in the clouds,
It sometimes may look frightening.
You see a quick electrical sparkFlash! Goes the lightning!
When a storm begins in the clouds,
It is truly wonderful.
You hear a rumble loud in the skyClap! Goes the thunder!
Long and thin and streaky and fast,
Its glow is oh so brightening,
Watch for the electric sparkFlash goes the lightning!
Lightning bolts are heating the air,
Over clouds and under.
When the air expands enoughClap! Goes the thunder!
What are four types of Severe Weather?
• Thunderstorms
• Tornadoes
• Hurricanes
• Blizzards

For the Teacher:
Common Weather Misconceptions
• Wind originates in the trees.
– Reality: Wind is a result of the sun warming the
Earth’s atmosphere unevenly.
• The seasons are the same everywhere.
– Reality: Differing climates lead to different weather
during the same season in other parts of the world.
• Weather, seasons, and climate are the same thing.
– Reality: Weather is the state of the atmosphere,
while a season is one of the four periods of the year
that begin at an equinox. Climate is the prevailing
weather conditions of an area.
