•At the end of the lesson, the learners will be able
to:
•• explain what a hazard is;
•• define the two main categories (Natural and
Man-made) of hazards; and
•• identify the impact of hazards common in their
environment.

RECALL:
• what are the natural processes that
shape and change our
environment?
6. Contoso
S u i t e s
• Hazard - A dangerous phenomenon, substance, human
activity or condition that may cause loss of life, injury or
other health impacts, property damage, loss of livelihoods
and services, social and economic disruption, or
environmental damage.
• Disaster - A serious disruption of the functioning of a
community or a society involving widespread human,
material, economic, or environmental losses and impacts
which exceeds the ability of the affected community or
society to cope using its own resources.

• 2. classify the phenomena in a table. You can classify
them in any way they want but you have to describe
the basis of your classification. write their answers in
their activity notebook. 3.
• Pair up with your seatmate you have to come up with
a final classification scheme written on a sheet of
paper.
• You should discuss the differences and similarities, if
any, and the basis for your classification with each
other.

NATURAL HAZARDS MAN-MADE AND
TECHNOLOGICAL HAZARDS
DEFINITION Naturally-occurring physical phenomena caused either by
rapid or slow onset events
A hazard originating from
technological or industrial
conditions, including
accidents, dangerous
procedures, infrastructure
failures, or specific human
activities.

Activity 2: Role Play
• This activity is meant for the learners to think
independently and their quick analysis on the
impacts of certain hazards according to specific
locations.

• A: Family in concrete house
near the highway far from
river and mountain
• B: Mountain climbers going up
the slope
• C: Exchange learners in a local
family home in the barrio near
the river
• D: Friends in a beach resort E:
Fishermen out on the sea
• F: Passengers in a jeep along
a road with moderate traffic

Imagine the impacts of certain phenomena (the hazards) on
specific settings
• A. There should be one reporter, who will explain what the group is representing
• B. The rest of the group, actors, will take on roles, whether of living or non-living things.
But there should always be at least one human in every situation. For example, they can
be all humans, or one human and the rest are either animals, plants, or inanimate objects.
• C. No member is needed to represent the hazard.
• D. The actors must represent what is happening to the living and/or non-living things
caught in the given situation. The assumption is that they are unable to avoid the
situation.
• E. 5-10 minutes to make a depiction.
• F. The grade will be based on the accuracy of the depiction of possible impacts, not on the
acting.
• G. Each group should submit the list of roles to the teacher. This will be used as a guide for
grading.
Editor's Notes
I. Plate tectonics – leading to mountain building, volcanism, ocean formation, etc. II. Atmospheric processes – formation of clouds, precipitation, wind, etc. III. Biological accumulation – reef building, colony formation, forestation, etc. IV. Human activities – urbanization, extracting resources, geoengineering, etc. V. Point out to the local environment any of the processes that have been mentioned.
Recall a recent or historical disastrous event. Ask the learners to tell the class what they know about it. 2. Emphasize how the Philippines is one of the most hazardous countries in the world, having more than 20 tropical cyclones in a year, earthquakes everyday, and more than 20 active volcanoes found all over the country.
DEFINE THESE IN YOUR OWN WORDS AND YOUR OWN DIALECT
(if odd numbered class, one group can be three learners)
Provide feedback after every play, mentioning the aspects they have missed.
