• Have you ever wondered why it sometimes rain
in one place but not in another place?
• Did it ever occur to your mind why we have storms and why
people can easily track their location and speed?
• What do you think is the phenomena behind it?
That is all because of weather. Now, I
want to know what is your idea of
weather or what comes to your mind
when you hear the word weather.
• Studying about the weather is important
because it affects our day to day
activities.
• That is why, people must be aware of the
daily weather so that they can plan things
well.
What is weather?
• Weather - It describes the condition of
the air at a particular time and place.
Weather also tells how the air moves
(wind) and describes anything it might
be carrying such as rain, snow or
clouds. Thunder, lightning, rainbows,
storms, and other special events are
all part of weather.
weather ???
• It is about the atmosphere
• It is a condition
• It keeps changing any time of the
day
• It varies from place to place
• It has a lot of elements
Weather is the condition of the
atmosphere at any given time.
How does weather differ from climate?
What is climate?
• Climate - It describes the average
weather conditions in a certain place or
during a certain season. Weather may
change from day to day, but climate
changes only over hundreds or thousands
of years.
• Many animals and plants need one kind
of climate to survive. Dolphins and palm
trees can live only in a warm climate,
while polar bears and spruce trees need a
cold climate.
What do you call a person who
studies the weather?
We call them Meteorologists.
What does he do?
Meteorologists study the
weather. He gathers information
by using special tools and
instruments to report it to the
people. He also helps trace
weather disturbances through the
use of these different weather
• Have you seen some weather instruments that are being
used to help the meteorologist tell the daily weather
condition of a place?
•
Do you know how to use them?
• Let’s do this matching type activity for me to know
whether you really know them or not.

Air thermometer
• Use to measure air temperature
• It is a hollow-glass tube with a liquid
(alcohol or mercury) inside.
• When the air temperature is high the
liquid inside expands or goes up but when
the air temperature is low the liquid
condenses and goes down.
Anemometer
• Measures wind speed
• The cups catch the wind, turning a
dial attached to the instrument. The
dial shows the wind speed.
Wind vane
• An instrument that determines the
direction from which the wind is
blowing.
Hygrometer
• Measures the water
vapor content of air or
humidity
Barometer
• Measures air pressure
• It tells whether or not the pressure is
rising or falling.
• A rising barometer means sunny or
dry conditions, while falling
barometer means stormy and wet
conditions.
Rain gauge
• Measures amount of rain that has
fallen over a specific time or period.
Weather maps
• Indicate atmospheric conditions
above a large portion of the Earth’s
surface.
Weather balloon
• Measures weather
conditions higher up in
the atmosphere through
a radar.
Weather Satellite
• It is used to photograph and track
large-scale air movements such as
typhoon / hurricane.
Processing:
 What can you say
about the different
instruments used by
meteorologist?
 Do you think
they are really
helpful?
 If you were a meteorologist
which among the instruments
will be your favorite? Why?
 How do you think people in
the past tell about the
weather? What instrument do
they used?
OUR EYES are one of the best ways to help
detect the weather.
Always keep an eye at the sky and you'll
usually be on top of weather conditions.
It is really fun to know these different instruments. Did
you know that different countries have their own
weather stations?
Weather station is the place where
all data about the weather are being
gathered and evaluated. They are
also the one who is responsible in
informing the people about the daily
weather condition of the country.

Weather is the daily condition of the atmosphere
at a particular time and place.
Meteorologists are people who study about the
daily weather condition of the place. They
record and report any information about the
weather.
Weather instruments are being used by
scientists to predict the weather. There are
many kinds of weather instruments from simple
to the most advance kind of technology.
