Title: Have you ever wondered why it sometimes rain


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
  • 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-556 A.M., Sunset- 608 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
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, haze and
    other special events are all part of 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
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.

8
Now, look at the pictures below. Which among the
pictures below shows a weather man?
A
D
C
B
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?
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?
  • Lets 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.

  • 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 Earths surface.

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

25
Processing
  • If you were a meteorologist which among the
    instruments will be your favorite? Why?
  • What can you say about the different instruments
    used by meteorologist?
  • How do you think people in the past tell about
    the weather? What instrument do they used?
  • Do you think they are really helpful?

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

36
New knowledge
  • 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.

37
  • 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.
  • The Philippine Atmospheric, Geophysical and
    Astronomical Services Administration 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
