sun’s heat and light.
For now, let us first discuss the
beneficial effects of the sun’s heat and
light!
Did you know class that sunlight can
improve our moods?
That’s right! sunlight can improve our
moods because sunlight increase the
brain's release of a hormone called
serotonin. Serotonin helps to improve
our moods.
So class if you feel sad or lazy you may
soak under the morning light but
always remember class you can only
stay under the sun without protection
before 10 o’clock in the morning and
after 4o’clock in the afternoon.
So again, on what time can we stay
under the sun without protection?

beautiful creation Ma’am.
Very good Melody!
With the light coming from the sun we
are able to see our beautiful
surroundings! You can see clearly the
smiling faces of your classmates
So aside from what Tricha and Melody
have given, there are some more
beneficial effects of sun’s heat and
light.
So here I will show some pictures and
tell me what have you observed.
So what can you observe in this
picture? Linalyn?

Very good Linalyn!
Plants can make their own food
through the presence of sunlight.

in the proper development of bones
and teeth.

observe? Mary Rose?
They are drying rice grains and fish
Ma’am.
That’s correct Mary Rose!
Both farmers and fishermen benefit
from the sun’s heat and light through
drying of crops and fishes.
Do you have any questions regarding
the beneficial effects of sun’s heat and
light Class?
You have learned some of the
beneficial effects of sun’s heat and
light, so now, we are going to discuss
its harmful effects. It is very important
that we learn the harmful effects of
sun’s heat and light not only on us,
but also to other living things like
plants and animals. Knowing its
harmful effects will make us take extra
precaution and to take care of other
living things around us.
None, Ma’am.
And class remember to limit your
exposure to the sun between 10 in the
morning and 4 in the afternoon
because sun's rays during these hours
can harm us.
Again, on what time we need to limit
our sun exposure? Lovely
In between 10 in the morning and 4
in the afternoon Ma’am.
Very good Lovely!
So again I Have here an image of a sun

have? Aleli?
8, Ma’am!
Correct! Very good Aleli!
The sun has eight rays and in this
image each ray corresponds a
question, if you know the answer,
raise your hand.
Are we clear?
What will happen to your
skin if it’s too exposed to?
the sun Melody?
Very good Melody!
Too much exposure under the sun
can cause sunburn and even skin
cancer.
Yes, Ma’am

That’s correct Mary Chris!
Looking directly to the sun especially
at noon can cause visual impairment.
Sweating too much because
of sun’s heat can lead to
what? Shamel?

Very good Shamel!
Sweating can cause loss of fluid in our
body that can lead to dehydration and
heat stroke.
What will happen to plants
when exposed to intense
sunlight? Jullienne?
That’s correct Jullienne!
They will wilt and die Ma’am.
Too much heat can also cause
dehydration to plant which cause
them to wilt and die.
What will happen to working
animals like carabaos when

They will get sick like humans
Ma’am.
Very good Christine!
Same with human, animals will get

That’s correct Lara!
Too much exposure to sunlight will
make soil to become very dry and may

common sign of premature-aging
What happens to our
immune system if we are
exposed too much to
sunlight? Tyrhon?
It weakens our immune system
Ma’am.
That’s correct Tyrhon!
Too much exposure to sun light can
harm our immune system. Immune
system is the one who protects our
body from harmful substances which
make us sick.
These are the harmful effects of the
Sun’s heat that can happen to us and
all living things that surrounds us.
Do you have any questions about the
harmful effects of sun’s heat and light
Class?
Now, we will have a group activity.
None Ma’am!
I have here a mystery box and it
contains various things which helps to
protect us from harmful effects of
sun’s heat and light.
Each group will have one
representative to come in front and
pick something from the box.
Later on, we will have a group
presentation. Each group will present
how these things will help us to
protect ourselves from harmful effects
of sun’s heat and light.
Items inside the mystery box
 Sunglasses
 Hat
 Umbrella
 Sunblock

 Bottled water
Now that you’re done with your group
activity, let us have your group
presentation, starting with group 1.
Wearing sunglasses will protect our
eyes from getting damage from
intense heat of the sun.
