I. CURRICULUM CONTENT, STANDARDS, AND LESSON COMPETENCIES
A. Content
Standards
Chemical properties of materials determine their uses.
B. Performance
Standards
By the end of the Quarter, learners describe chemical properties of materials and changes to them. They
demonstrate an understanding that science processes can solve everyday problems and use creativity and
determination to provide examples. They exhibit objectivity and open-mindedness in gathering information
related to environmental issues and concerns in the community.
C. Learning
Competencies
Describe changes in properties of materials when exposed to certain changes in temperature, such as changes
when wood or coal are burned.
D. Learning
Objectives
At the end of the lesson,
the learners should be able
to identify changes in the
materials that are useful
and harmful to the
environment.
At the end of the lesson, the
learners should be able
describe the effects of some
materials could be
minimized.

Lesson Purpose/Intention
The teacher explains to the
learners that the cycles of
nature are disrupted due
to the different human
activities like burning of
wastes, dumping of waste
materials in the river, and
the like.
The teacher explains to
the learners that the
harmful effects of the
materials in the
environment could be
lessened or minimized.
The teacher explains to the
learners that the harmful
effects of the materials in

The teacher explains to
the learners that reactive
materials could pose
danger to property and on
one’s life. The negative
effect of reactive materials
could be minimized and or
deterred.

Idea/Stem
Passage Reading

Numerous human
activities such as
overpopulation, pollution,
the burning of fossil fuels,
and deforestation have an
adverse effect on the
physical environment.
Climate change, soil
erosion, poor air quality,
and undrinkable water
have all been brought on
by changes like these.
These unfavorable effects
may influence human
behavior and lead to large-
scale migrations or
conflicts over access to
clean water.
Passage Reading

Effective implementation
of the "Three Rs"
(Reduce, Reuse, and
Recycling) campaign is
required to encourage
improved trash
management. You would
be better off donating the
old jeans and using
reusable shopping bags
rather than turning an
old pair of jeans into a
bag that requires
constant maintenance.
Some initiatives could
have a long learning
curve and take practice
to become used to.

Passage Reading

Reactive materials are
typically thought of as
substances that, when
exposed to heat, pressure,
shock, friction, a catalyst,
or contact with air or
water, can become
hazardous on their own.
Reactive interactions call
for the blending of two or
more substances in order
to create a risky scenario
through a chemical
reaction.

The phrase "air pollution"
is very general and covers
a wide range of chemicals
and airborne particles.
These pollutants can
originate from many
different places, such as
automobiles, factories,
power plants, and even
open fires.

Burning fossil fuels, like
coal, oil, and natural gas,
is the main source of air
pollution. These
substances emit dangerous
compounds into the air
when they are burned,
such as carbon dioxide,
nitrogen oxides, and
sulphur dioxide. Lead,
ground-level ozone, and
particulate matter, which
are microscopic bits of
solids in the air (such soot
and dirt), are some other
air pollutants.

These gases and pollutants
can harm people's health
in many ways, including
heart disease and a
number of respiratory
conditions like asthma,
Although sorting
recyclables can be
difficult at first, after you
get the feel of the
method, the associated
tasks will come naturally
to you.

The most important way
to reduce waste is to cut
back on how much you
buy. The secret is to only
buy the things we
actually need, and in the
proper quantity. We
won't need to mine raw
materials, create items
from scratch, create
shipping materials, use
more resources to send
them, and then figure
out how to get rid of
them if we never produce
them in the first place.

Many people find the
thought of being
wasteful unsettling.
However, the majority of
us still waste because we
are unable to come up
with a better use for
items like last year's
phone book, overly short
draperies or a scratched
closet door. Because of
feel of the method, the
associated tasks will come
naturally to you.

Ask:
1. What can you say of the
picture?
2. What makes the area
polluted?
3. What happens if the
activities will be done
continuously?



Nature Walk Strategy
This activity would be
done prior to the delivery
of instruction to avoid
overtime. Let the learners
walk with their
classmates and visit the
entire premise of the
school if possible.
Learners should list
materials that they have
seen and identify if it
could be reuse, reduce,
and or recycle.

Picture Analysis
The teacher provides
pictures by groups. Each
group will list materials
that they have seen and
identify if it could be reuse,
reduce, and or recycle.

The teacher presents a
video on how reactive
materials could endanger
human lives and
properties.
