kmt good day
kids today we will learn about energy is
everywhere sources and uses of light
energy here are the possible objectives
for today's lesson number one recognize
that energy exists in various form forms
and can be transferred from one object
to another and transform from one form to
to
another number two identify and
distinguish between different forms of
energy including light sound and heat
energy number three recognize that light
energy is a form of energy associated
with the emission of visible
light number four identify sources of
light energy at school home and in the
community number five save energy in own simple

vocabulary energy is the ability to do
work this means that energy makes things
happen the Sun as the principal source
of energy for the earth makes other
possible energy transfer is the process

time the adventure continued with Mia
picking up her pencil when Mia writes
with her pencil she's using energy from
her muscles but did you know that the
pen SE itself has stored energy when she

example what is the purpose of telling the
the [Music]
[Music] story
story
excellent the purpose of telling the
story Whispers of energy a day in a
world of Wonders is to provide an
engaging and accessible narrative that
introduces to the fourth grade pupils
the concept of energy being everywhere
and its ability to cause changes through
the story the aim is to make the
abstract idea of energy more relatable
and understandable for us Learners by
weaving it into relatable everyday [Music]
[Music]
experiences energy
chain arrange the pictures starting from
the source of the energy onto its last
energy transform information chain [Music]
one let's
answer number one is the Sun as the
source of
energy to be transform into number two the
the
vegetable note that vegetables are
growing because of the
sun of course number three vegetables
are to be eaten by
human because of it the energy is
transformed or changed into the
capability of human to play which is the number
number [Music]
[Music]
four let's now proceed to chain number
two now do it yourself arrange the
pictures starting from the source of the
energy onto its last energy transformation
transformation [Music]
[Music]
let's check your
answer number one will be the
Sun the energy will be passed or changed
into the number two which is
grass then a cow will eat the grass and
get the energy this is number
three lastly the energy will change into
milk to be drunk by [Music]
[Music]
human day or night this activity is to
be guided by your actual picture [Music]
second lesson different forms of energy
including light sound and heat [Music]
[Music]
energy different forms of
energy number one light energy this is
energy that travels in waves and can be
seen by our
eyes it's what makes things visible the
Sun light bulbs and flashlights all
produce light energy light energy can
travel through space which is why we can
[Music]
away number two sound energy this is
energy that travels in waves through air
or other materials and can be heard by
our ears [Music]
[Music]
number three heat energy or thermal
energy this is the energy that comes
from the movement of tiny particles in
matter the faster these particles move
the more heat energy they have we feel
warmth third lesson sources and uses of
brainstorming session this activity is
to be guided by your actual [Music]

make their food which is essential for
their growth and for providing
oxygen number three warmth the sunl also
provides warmth which is crucial for
life on Earth [Music]
number four electricity solar panels
convert sunlight into electricity
providing a renewable energy

us see in Dark Places and sunlight
exposure can boost our vitamin D
production however some light sources
can have negative Health impacts such as
I strain from staring at bright lights
and there are also hazards associated
with prolonged sun [Music]
[Music]
exposure Learners
takeaways values integration saving energy
energy
a lot of energy is wasted by using more
than we need saving energy means using
less energy by not wasting it and using
only the energy we
need how can you save [Music]
energy very good we can save energy by
turning off lights and electronics when
not in use taking shorter showers and
day I already save energy by please
complete the [Music]
