This document discusses using the KWL strategy to teach about global warming. It begins with an introduction to KWL charts and how they work by having students identify what they Know, Want to know, and have Learned. It then provides a sample KWL chart on global warming where students listed what they already knew about causes and effects of global warming, questions they had, and space to add what they learned. The document defines key terms, lists causes and effects of global warming with images, and proposes solutions. It concludes by directing students to watch an explanatory video and complete the final L column of the KWL chart.

1. KWL IN USE

2. Hello!
I need a translator
Feel free to ask about the meanings
of words you don’t know

3. Elements of the discussion
1- kWL as a learning strategy.
2- kWL sheet (work paper).
3- Practical application on KWL.
4- sample video.

4. 1.
KWL as a learning strategy.
Let’s start with the first set of slides

5. A KWL table, or
KWL chart, is a
graphical
organizer
designed to help
in learning.
5

6. It was
created by
Donna Ogle
in 1986.
6

7. The letters KWL are :-
K= what students Know!
W= what Ss Want to know!
L=what Ss need to Learn.
7

8. A KWL chart can
be used for all
subjects in a
whole group or
small group
atmosphere.
8

9. The chart is a
comprehension
strategy used
to activate
background
knowledge
9

10. KWL is
completely
student
centered.

11. 2.
KWL sheet (work paper).
Let’s start with the second set of slides

13. (K)
Elicits students’
prior knowledge
of the topic of
the text.
13

14. (W)
By writing what
they want to
know the Ss set
a purpose for
reading.
14

15. (L)
Helps students
to monitor
their
comprehension

16. 3.
Practical application on KWL
Let’s start with the third set of slides

17. Global Warming
17

18. Global Warming
- Difference between global warming & Climate change.
- The Reasons of Global Warming. (Why)
- The Consequences of Global warming.
- How to overcome this Problem.
(Solutions) “HOW”
18

19. Global warming:-
It is the increase of the
Earth’s temperature
due to a build-up of
greenhouse gases in
the atmosphere.
Difference between Global warming & Climate change.
Climate change:-
It is a broader term
that refers to long-
term changes in
climate, including
average temperature.
19

20. The Reasons of Global Warming:
- POLLUTION FROM COAL,
NATURAL GAS, AND OIL.
- CO2 FROM AIRPLANES &
VEHICLES.
- POPULATION INCREASE.
- DEFORESTATION.

26. The Greenhouse
Effect
26

27. • Greenhouse Gas: A gas
which traps the sun's heat:
• Water vapor (H2O)
• Carbon dioxide (CO2) -
exhaust from cars and
power plants (electricity).
• Methane (CH4) - from
decomposing organic
matter.
27

28. 28
- The greenhouse effect is when
the temperature goes up, on
Earth, since the sun’s heat and
light energy is trapped in the
earth’s atmosphere.
- While the heat from the sun
enters our atmosphere, the heat
has trouble leaving back
out our atmosphere

31. Green house gases
act like a mirror
which reflect a
part of heat
radiation back to
the earth.

32. “Quotations are
commonly printed as a
means of inspiration and
to invoke philosophical
thoughts from the
reader”
32

33. The Consequences of Global Warming:
- Melting of glaciers.
- Polar Bear Extinction
- More hurricanes
- Increased Temperature.
- Melting Polar ice caps.
- Increased droughts and
heat waves.

37. 37
Between 1970
and 2004
global
greenhouse
gas emissions
have increased
by 70 %

38. Global surface temperatures
– increased about 0.6°C since
the late 19th century.
– increased to 2°C over the
past 25 years.
- Heat waves, droughts, and
wildfires will be more frequent.

39. Sea level rising
rising at an average rate of
1 – 2 m/year over the past
100 years.
Global sea levels could rise
by more than 20 feet,
devastating coastal areas
worldwide.
Storms & Hurricanes

42. > the Arctic Ocean
could be ice free
in summer by
2050.
42

43. > Up to 300,000 people a
year will die – partly
from the spread of
tropical diseases.
43

44. > More than a million
species worldwide
could be extinct by
2050. (Endangered)
44

45. 45

46. Most scientists blame
> Industrialization:
Automotive Industry
(low fuel economy)
> Oil companies
(fossil fuels)
46

47. > Power plants
(coal)
> Agri-business
(biofuels, cattle
producing
methane)
> Logging Industry
(deforestation)

52. Big concept
Bring the attention of your audience over
a key concept using icons or illustrations
52

53. 53
The earth is too old to stand up
through this phenomena.
Therefore, we, as the khalifa
living in it are responsible to
ensure the beauty of the world
can be enjoyed by our kids in the
future. If we, as the soon to-be-
forefathers do not find a way to
overcome this problem,

54. 54
imagine how would
the future generation
survive with a climate
that is hotter than it
already is now?
