Very good!

B. EXPLORE

1. Motivation
I guess we can now move on to our
next topic for today. But before we
proceed, I prepared a video clip that
you need to watch.

Let me just ask you first. What are the 1. Keep quiet.
things that you need to do while you 2. Avoid unnecessary movements.
are watching? 3. Observe and just listen.
Very good class!

Class, what is the video clip all about? It’s all about state of matter and changes of
state.
Very good!

2.Presentation

Okay Class, Based on the video

clip, what do you think is our About Solid, liquid and Gas teacher!
lesson for today? Do you have any
idea?

Very good.

Teacher, The lesson for today is about

Another idea. Anyone? How solid, liquid and gas changes.

Very good!

If the candle wax is heated or

cooled, what do you think will
happen to it?

If the water is heated, what do you

think will happen to it?

If the naphthalene ball is heated,

what will happen to it?

And if the water is cold what do

you think will happen?

This is what we will experiment on

today.

3.Pre-Activity

I will divide you into 4 groups. Each

group will prepare the material you
need to use in our experiment today.

but before we proceed to our activity, Let’s follow the GROUPS. Teacher!
What are the standards that we need
should be following again?
That’s right. Let’s follow the groups
while doing the activity.
What does the acronym GROUPS
again?
Can you all give me the meaning of Get along
each
Letter? Respect others

What does G mean? On task

What does R mean? Use quiet voices

What does O mean? Participate

What does U mean? Stay in your group

What does P mean?

What does S mean?

Okay Very good!

You will perform this activity in 10

minutes.

Each group will have a leader to None, Teacher.

demonstrate your understanding on
the experiment.

Any question children?

(Experiment time )

4.Activity Proper
Let the pupils’ do the activity
Each group needs to do different task.

The first group will do the experiment

that you need to discover how the
solid form change into a liquid form.

The second group will do the

experiment that you need to discover
what will Happen when the water is
exposed in the heat.

The third group will do the experiment

that you need to discover what will
happen when the naphthalene ball is
exposed in the heat.

The designated leader will Share his/her

And the last group will do an observation about the experiment.
experiment that you need to discover
what will happen to water when it is
cold.

After doing these activities observed it

and tell me the changes that you have
noticed in each experiment.

C.EXPLAIN

1. Group Reporting

I’m Glad that you all performed the The volunteer will go in front
activity. Now, may I ask a volunteer
reporter in one group to share to the When I put the little candle wax in the
class the result of their activity spoon and put it on the fire, it melted and
became liquid.

Very good!
When the water exposed in the heat the
formed change and there is a smoke came
out in the water. So from liquid turns into
Very well said! gas.

Very good children.

You may now take your seat.

2. Discussion

Class, what do you observed from the

activity that we’ve done? Teacher! We observed that when a solid
material is heated by fire it will dissolve and
it will form as a liquid and produce smoke
which we call gas.

Very good! Any other answer or

observation from our experiment? We also noticed that when the water is
heated or boiled there is a smoke coming
out and the water inside are decreases.

So what do you think is called to the

smoke coming out from that boiling Its evaporation teacher!
water?

Yes. Very good!

What do you think our topic is all Our topic will be all about changing forms of
about? solid, liquid and gas

That’s right.

I will show you more pictures so you

can better understand our topic

Changing forms of matter is

When a substance goes from one
state of matter, solid, liquid or gas to
another state of matter, the process is (the pupils are Listening)
a change of state. Some rather
interesting things occur during this
process.

From Solid to a Liquid

 It will melt, teacher!

There is a special temperature for

every substance called the melting
point. When a solid reaches the
temperature of its melting point, it
can become a liquid. Yes, teacher!
For water, the temperature needs to
be a little over zero degrees Celsius Is the transition between solid to liquid,
(0oC) for you to melt. teacher!

It’s called the melting point teacher!

Yes, teacher

The candle is starting to melt teacher.

Melting is the transition between solid

to liquid state.

For example, when margarine is put in

Yes, teacher!
a hot pan, What happens to
margarine?
Another example,
Ice is a kind of solid teacher.
Gelatin powder mixed with hot water.
From solid gelatin powder to liquid.

Understood ?
- Margarine heated in a pan teacher.
What is melting again?
 - Ice candy teacher

What is special temperature for every

substance again? - Gelatin powder mixed with hot water

Very good!

Just like our first experiment right?

What happened to the candle wax

again when it was heated by the fire?

Okay, Very good!

Another example is an ice,

Ice is made of water right?

What kind of phases of matter is ice?

Is it Solid, liquid or gas?

Okay very good!

Can you give me some examples of

solid to liquid?

Anyone?
Just raise your hand if you want to
answer. When the water put it in the freezer, it
becomes freeze so that it becomes solid.

Great job children!

Now we proceed to Changing form of

liquid to solid.

It will start to freeze and become solid

Freezing is the change of state from a liquid

to solid, teacher!
 Ice candy teacher, when ice candy put it in
the freezer, it become freeze so it will also
become solid

- Gelatin mixed with hot water and

placed inside the refrigerator.

- Ice cream that put in the freezer

teacher!

- From water to Ice cubes!

So based on the picture what do you
think is the reason why liquid
becomes solid?
None, teacher!
Very good that’s right!

Suppose more energy or heat is

extracted from liquid as if the liquid
ice is put in the freezer where the
temperature could be 0°c or much
below the liquid particles may be slow
down. They continue getting closer to
one another. If the particles lack some
energy the ice begins freezing. The
transition of condition from a liquid to
a solid is freezing.

For example,
Gelatin mixed with hot water,
If you put gelatin mixed with water in The naphthalene ball creates bad odor and
the refrigerator what will happen to it? dark smokes, teacher!

What is freezing again?

It’s called gas that evaporate to the air
Very good!

Can you give me more example of

liquid to solid? Any volunteer?

Very good!

What else?
All your answers are correct.
Very good children!

Is there any question?

And the next is Solid to gas.

Based on our experiment a while ago

what do you observed or noticed
when the naphthalene ball is heated?

What do you think is called to that

bad odor and dark smokes?

Very good!

naphthalene, are converted directly

ample energy to form a gas. Particles phase
in a solid do not move into the liquid
state during sublimation, because
they contain gas. As a solid material
sublimates into a gas, its particles’
freedom of movement increases. In
the case of naphthalene balls, the
material solid disappears; however, its
odor can be smelled in the air.

It’s like a tiny bubbles that floating upward

Deposition chemistry occurs when The water evaporated.
molecules settle out of the gas phase
and into the solid phase.

What is sublimation again?

How about Deposition?

Very good!

Next. When water changes from a liquid to a gas

or vapor, teacher!

- The smoke coming out of a hot cup of

tea or coffee

- Hanging wet clothes under the sun

Evaporation (Liquid to Gas)
 is When water vapor in the air changes into
What can say about the picture? liquid water.

Yes, you’re right.

Do you remember the last experiment

that we’ve done a while ago? What The pupils will do so.
happen to the water when heated?

What do you think will happen or

where did that water go?

Yes, because Evaporation is When

water changes from a liquid to a gas
or vapor.

What is evaporation again ?

Very good!

Can you give me 2 example of

evaporation?

Very good, class!

Next is
Condensation is When water vapor in
the air changes into liquid water.

What is condensation again?

Very good class.

May we all stand and do the power

clap.
