Small mirror
Old colored magazines
Craft paper or coupon bond
Crayons
Marker
Scissors
Book
What to do:
1. Draw or cut out magazine
pictures that have symmetry- stars,
faces, flowers, butterflies, etc. Cut
the pictures into half.

examples/
instances of the new lesson
4. When somebody faces a mirror,
his reflection can be seen in
reversed manner.
5. Loudness of sound depends on
the area of the vibrating body and
distance of the listener from the
source of sound.
6. The stronger the source of light,
the bigger the shadow and the
bigger the source of light, the
smaller the shadow.
7. Light can either be absorbed or
reflected
by
the
object.
Absorption and reflection of light
cannot happen at the same time.
When
you
look
at
your
surroundings, you recognize the
things around you. How are you
able to see things? Do they
produce their own light so that you
can see them?

feet from above the surface of the
water while you are in a swimming
pool?

you cannot see; thus, you will not
be able to do what you need to do
or go where you want to go.

water. Look at it. Feel it. Is it straight
or bent?
Do the Activity:

You max use an open area in your
school that is free of obstruction
from tall trees or building.
2. Place a sheet of white paper on
the table. The paper should be
positioned at the back of the glass
of water. Observe the rays of the
sun that passes through the glass.
Write your observation in your
science notebook.
3. Now draw shapes and designs,
cut them in halves, and repeat
number 2.
4. Exchange your drawing with a
partner and have fun completing
each half of the drawing using the
mirrors.
5. Next, hold up a printed copy of
a text from a book or magazine to
your mirror.

your classmates made, when you
placed them beside the mirror?
3. Can you do this with other
drawings or cut-outs that are not
symmetrical? Explain your answer.
4. What will happen when you cut
the drawings crosswise instead of
lengthwise, and place them
beside a mirror? Will you get a full
view of the picture?

practical
application of concepts
and skills in daily living
Look at the diagrams below and
describe what each tells about the
properties and characteristics of
light.
Draw five examples of materials
that reflect light.
Draw five examples of materials
that refract light.
Write three (3) sentences on how
you can protect yourself from
exposure to excessive light.
H. Making Generalizations and
Just as heat and sound travel, so
does light. Light travels in straight
lines. Sometimes it bounces back
into the direction of the source. We
call this reflection. Water, windows,
shiny metal, and mirrors are just
some of the many objects that
reflect light. As light travels, it
travels in a straight line. However,
when light passes from one
material into a second material like
mirror or water, the light path is
either bent or reflected.
The way light bounces back is very
much similar to the way a ball
bounces back on hard smooth
surface. When you throw a ball
straight down, it will bounce
straight back at you. When you
throw a ball at an angle, it will
bounce off at the same angle
away from you. Light reflects the
same way off a mirror. Light
bounces off at the same angle
that it struck the mirror.
Refraction is the bending of light as
it travels from one type of material
to another like from air to water.
This bending by refraction makes it
possible for us to have lenses,
magnifying glasses, prisms and
rainbows. Even our eyes depend
upon this bending of light.
White light has different colors
which is the color of the rainbow.
The colors of the rainbow and all
the other colors that we see
around us are colors that come the
light of the sun.
A rainbow is formed when the light
from the sun passes through
raindrops. That is why we see a
rainbow after it has rained. A
rainbow is the results of sunlight
breaking into different colors.
In the activity, the glass of water
reflects light. As the light bends, it
separates into different colors or
the colors of the rainbow, which is
red, orange, yellow, green, blue,
indigo, and violet or the ROYGBIV
