Prepare a candle and a match.
Light the candle and observe
how it changes after 2 to 3
minutes.
What happened to the candle
after being exposed to heat?
C. Presenting examples/
instances of the new
lesson.
What you have felt is a form of
energy. Heat makes us feel
warm or hot (Abadilla, 2009)
Why did the ice cubes melt? Heat causes physical changes,
sometimes chemical changes in a
substance also happen. A physical
change is a change in size, shape,
or state of substance. There is no
new substance formed after a
physical change. A chemical
change involves the formation of a
new substance (Lemi, 2007).

3. rubbing surfaces to move faster
and have more energy. You will
feel warm after rubbing your
hands against each other several
times. It comes from the
increase in motion of molecules
in a body.
Sun is our main source of heat.
The sun’s heat is absorbed by
the bodies of water, the ground,
the plants, and the atmosphere.
(Ramos and Apolinario, 2017).
Electricity is one of the sources
of heat. We use many electrical
appliances for the heat they
give.
Burning fuels can produce heat.
A substance that combines with
oxygen rapidly produces heat
fast enough to cause flame.
When coal, wood, natural gas,
or any other fuel burns,
substances in the fuel combine
with oxygen in the air to form
heat. This reaction is known as
combustion (Ramos and
Apolinario, 2017). Example of
the pupils. Ask them to name
the pictures.
made of melts when lighted or
heated.
The change from solid to liquid is
called melting. Any solid material
that changes to liquid through the
process of heating undergoes
melting. An ice cube becomes
liquid when it absorbs molecules
of heat (Lemi, 2007).
When heat is applied continuously
to water, the particles escape and
enter the air as water vapor.
Water vapor is a gas. The change
of state from liquid to gas is called
evaporation (Lemi, 2007).

4. combustion is the burning of
gasoline in automobile engines.
There is also heat from deep
inside the earth and it is called
Geothermal heat. We observe
some of this heat when a
volcano erupts. We also have
hot springs because of the
heated hot rocks within the
earth.
E. Discussing new concepts
and practicing new skills
#2.
Emphasize the following
concepts.
• There are different things
that give off light.
• The Sun is the main source of
light.
There are things that look like
they are sources of light but
actually reflecting light only.
Examples: moon,
disco/mirror/glitter ball
Chemical Change
Heat causes substance to change
chemically. After heating, a new
substance may be formed.
Combustion is a chemical reaction
that gives off heat and light.
Combustion produces heat and
fire. Example of combustion is the
burning of gasoline in automobile
engines. The process produces
heat that cause the gases in the
engine to expand and move parts
that make the engine work.
