1. • 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.

2. • Use the cloud 3 drops to note your ideas. You will
be given 5 minutes to work on this on your
notebook.
Processing:
1. Where did you get this idea about
weather?
2. Why did you say that weather is or
has something to do with
________?
3. Do you know what will be the kind of
weather today? tomorrow? next
day?

3. • 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.
So, what is the meaning of weather?
Let us read and study this sample weather
forecast or news.

4. Read the sample weather forecast.
• No major weather disturbance will affect the country which will
continue to experience fair weather except for scattered rain showers
over Bicol region, Eastern Visayas and Mindanao. Light easterly to
southeasterly winds will prevail throughout the archipelago and
coastal waters will remain slight.
• Metro Manila- partly cloudy with range of temperature- 22 – 35
• Metro Cebu- Cloudy skies, temperature- 26 – 31
• Metro Davao-partly cloudy, temperature- 24 -34
• Baguio- partly cloudy, temperature- 14 – 26
• Sunrise-5:56 A.M., Sunset- 6:08 P.M.
Processing:
1. What is the weather forecast for the country today?
2. Which areas of the country will experience rain?
3. What is the direction of the wind?
4. Which place will experience cold weather?
5. What area will experience the highest temperature today?
6. Is weather condition the same in all the places?
7. What is weather?

5. • 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, haze and other
special events are all part of weather.
What is weather?

6. 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?

7. • 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 is climate?

8. Now, look at the pictures below. Which among the pictures
below shows a weather man?
Processing:
1. What made you say that he is a weather man?
2. What does a weather man do?
3. In science, what do you call a weather man?
A DCB

9. What do you call the person who study the
weather?
We call them Meteorologist. Everybody say
METEOROLOGIST.
What does he do?
Meteorologist study the weather. He gathers
information and reports it to the people. He
also helps trace weather disturbances
through the use of different weather
instruments.

10. • 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.
• In your notebook identify the following materials by
writing their names. Choose your answers from the box
below. You are given 3 minutes to do this activity.

12. • Using a variety of weather instruments, maps
and reports, meteorologists study the ever-
changing weather information in order to
discover trends and patterns which help them
forecast the weather for the next few hours and
days.
• Meteorologists can now give advance warning
on extreme weather conditions so that
communities can prepare for the worst.

14. So, what are the different weather instruments
they use to gather information?
• Air thermometer
• Anemometer
• Wind vane
• Wind sock
• Hygrometer
• Compass
• Barometer
• Rain gauge
• Weather maps
• Weather balloon
• Weather satellites

15. 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
goes down.

16. Anemometer
• Measures wind speed
• The cups catch the wind, turning a dial
attached to the instrument. The dial
shows the wind speed.

17. Wind vane
• an instrument that determines the
direction from which the wind is blowing.

18. Weather balloon
• measures weather
conditions higher up in the
atmosphere through a
radar.

19. Hygrometer
• Measures the water vapor
content of air or humidity
Sling Psychrometer
measures relative humidity, using
the cooling effect of evaporation.
Two thermometers are used in a
sling psychrometer.

20. 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.

21. Rain gauge
• Measures amount of rain that has fallen
over a specific time or period.

22. Compass
• is a navigational instrument for
finding directions.

23. Weather maps
• Indicate atmospheric conditions above a
large portion of the Earth’s surface.

24. Weather Satellite
• It is used to photograph and track large-
scale air movements such as typhoon,
hurricane etc.

25. 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.

26. 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.
In the Philippines we also have our own weather
station. Do you know what is it?

27. In the Philippines we have a weather station that
gives the daily weather report and observation we
call it PAGASA.
What is the meaning of PAGASA?
Philippine Atmospheric Geophysical
and Astronomical Services
Administration.
Memorize it kids!!!

28. • PAGASA is a Philippine national institution dedicated to
provide flood and typhoon warnings, public
weather forecasts and advisories, meteorological,
astronomical, climatological, and other specialized
information and services primarily for the protection of
life and property and in support of economic,
productivity and sustainable development.

29. • Let us see if you really learned something today? With a partner
(pair share), complete the concept map below in your notebook.
You are given 10 minutes to do this. Then, be ready to share your
work to the class.
