PRESENTATION OF THE OBJECTIVES

For us to be properly directed in
discussing our new topic, kindly read
the objectives class.
At the end of the lesson, student should be
able to:
a. Explain comets, meteors and asteroids
b. Classify examples as comets, meteors
and asteroids and;
c. Develop an appreciation for comets,
meteors and asteroids

Alright! Let’s work together to attain

the desired learning outcomes for
today’s topic.
Can we do it class?
Yes Ma’am

C. EXPLORE (pre-activity)
At this moment, I have another
activity. It is called “Word Bank”. I
have here different words which I will
give you. What you have to do is to
paste these words under which
categories you think it belongs to.
Am I clear class?
Yes Ma’am
(the students will do the activity)

Okay! Do you think these pasted

Yes/No Ma’am
words here are correct?

Okay we will find it out later. Thank

 you for those who answered.

D. EXPLAIN
Now class, based on your activity
earlier, what do you think is our topic
for today?
Yes _______?
Ma’am, I think that our topic for today is
about comets, meteors and asteroids.

That’s right. We’re going to discuss

the lesson 2; Earth’s Farthest
Neighbors

Class, what are the things that comes

into your mind when you hear the
word solar system?
Yes _______? Ma’am, the first thing that comes into my
mind is the sun and the nine planets.

Alright, thank you so much. What

about the comets, meteors or
asteroids? Do you know that they are
called left-overs? No Ma’am

Why do you think they are called left-

over materials? (the students will share their ideas about the
given question)

Okay. They are believed to be

leftovers from the huge cloud of gas
and dust and what condensed to form
the solar system

Do you know that the knowledge

about the comets, meteors and
asteroids already existed in ancient
times? These celestial visitors were
thought of as bad omens or signs of
great change such as disaster or wars.

But, as you all know, with new

scientific processes and tools, these
celestial visitors or what we called
Near-Earth Objects (NEO) have (the students are listening attentively)
gained a lot of appreciation and
interest by many people, especially
scientists.

As this moment, we’re going to

discuss about the three different rocks
that are also found in space.

Let’s first discuss the comets.

(the teacher will show a picture of
comet)

Now based on the picture, what do you

think comets are?
Yes, ___________? Ma’am, comets are cosmic snowballs of
frozen gases, rock, and dust that orbit the Sun.

That’s correct. Thank you _______.

Another?
Yes, ________?
Ma’am, they are also called as dirty snowballs

That is also correct. Thank you

______

So, comets are cosmic snowballs made

up of frozen gases, dust and particles.
Some scientist believe that comets
provides important information on the
formation of the solar system

The ice is frozen water, ammonia,

methane, and carbon dioxide. They are
mixed with rocks and metal too and
covered by a layer of black dust that’s
why they are like dirty snowballs.

So now, comets have several parts.

(the teacher will show the picture of
comet’s parts)

The comets have a nucleus, coma and

a tail.
(the student are listening attentively)

How do they differ from each other?

The nucleus of comets is made up of
ice and particles of dust and rock
glued together by ice. It is sometimes
described as “dirty snowballs”

Next is the coma, it surrounds the

nucleus, a gaseous atmosphere that can
have a diameter of up to thousands of
kilometers

(the teacher will show the picture of a

coma)

The last part of a comet is its tail

where it composed of two tail; the dust
tail and the plasma tail

(the teacher will show the picture of a

tail)

Now, how do they differ from each

other? Ma’am, a dust tail is made up of small solid
particles and plasma tail is made up of ionized
gas
Very good, That’s correct
A dust tail is made up of fine dust
particles, is broad and slightly curved.
The plasma tail is made up of ionized
gas that is narrow and straight and
points away from the sun.

Now a comet comes from two regions.

The first one is the Kuiper Belt which
is just beyond Neptune’s orbit and the
Oort Cloud which is located in the
outer boundary of the solar system.
(the teacher will show the picture of
Kuiper belt and Oort cloud)

There are also 2 types of comets; we

have the short-period comets and long-
period comets.

A short period comet are those that

orbit the sun every 20 to 200 years
while long period comets takes
thousand and even millions of years.

The example of a short period comet is

the Halley’s comet named after the
Edmund Halley and long period comet
is the Hale-Bopp.

(the teacher will show the picture of

Halley’s comet and Hale-Bopp)

Is there’s any questions regarding the

comets? No Ma’am

Alright! Now, let’s proceed to

meteors.

When we hear the word meteor, what

does it mean?
(the teacher will show a picture of
meteors)

Anyone? Yes __________?

Ma’am, meteors are called shooting stars.

That’s right! What else?

Yes _________?
Ma’am meteors is a space rocks that
composed of thousands of rocks.
That is also correct.

When we say meteors, it is a huge

fragment of rocks and debris in space.
They are the particles that have not yet
reach or will not reach the Earth’s
surface. It will enter the Earth's
atmosphere and burn up, creating a
bright streak of light in the sky, known
as a meteors or a shooting star.

What about the meteorites? Ma’am, meteorites survives the journey

through Earth's atmosphere and lands on the
Earth's surface

Alright! Thank you very much.

So large meteors usually break into
pieces due to the great force they
experience as they fall into Earth due
to gravity. The small rocks surviving
after an impact are called meteorites.

Is there’s any questions regarding the

meteors? No Ma’am

(the teacher will show the video about

meteors)
Let’s proceed to asteroids.
(the teacher will show a picture of
asteroid)

So based on the picture, what do you

think is an asteroid?
Anyone?
Yes ________? Ma’am, an asteroid is a rocky objects that
orbit the sun

Very good _______!

Asteroid is the largest among these

three kinds of space rocks, a rocky and
metallic object that have been left
behind during the formation of planets.
It also called the minor planets.

Asteroids are mostly concentrated in a

region between the Mars and Jupiter
called the asteroid belt. So asteroid
belt has an inner and outer part. The
inner part is made up of asteroid that
contains metal like gold, iron,
platinum and nickel. The outer part
contains asteroids mostly made up of
rocks. Also there are millions of
asteroids in the solar system but 3,000
of them have been named.
(the teacher will show the picture of
asteroid belt)
Now who can you give me an example
of asteroid?
Yes ________?
Ma’am an example of asteroid is the Ceres.

Very good, and that’s right. Ceres is

thought to be the largest asteroid in
our solar system. It is about 295 miles
around. And because it is so big,
scientist named Ceres as “dwarf
planet”
(the teacher will show the picture of
Vesta)

Can you give me another example?

Yes _______?
Ma’am another example of an asteroid is the
Vesta which is the second largest asteroid in
solar system.
Fabulous! Thank you very much.

So, Vesta is the second largest asteroid

in the solar system and it is also the
brightest asteroid. Every so often it
can be seen from Earth without a
telescope.
(the teacher will show the picture of
Vesta)
 So do you understand the comets,
meteors and asteroids?
Yes Ma’am
Alright!

ELABORATE
To see if you really understood the
comets, meteors and asteroids, we’re
going to have another activity. It is
another guessing game.

I will give you a worksheet and you’re

going to identify this celestial object
based on their characteristics.

Okay! You may now answer.

Characteristics:
Also known as “Dirty Snowball” Comets
Made up of metals and rocky material Asteroid
Orbit between Jupiter and Mars Asteroid
Often called “shooting star” Meteors
Usually burns up the Earth’s Meteors
atmosphere
(meteors)
Made up of dust and ice rock Comet
Asteroids
Also called dwarf planet
Meteors
Appears as a streak in the sky
Meteors
Broken pieces from asteroids or
comets Comet
 Originate from Kuiper Belt and Oort
cloud

After 5 minutes, the group will present

their work in front.

Do you understand class? Yes Ma’am

Generalization
Did you learn from our lesson for
today? Yes Ma’am
Very good and I believe that you have
understood well the comets, meteors
and asteroid. Now let’ quickly sum up
our lesson.

So I have this activity called paper

rolling. You will pass this circled
paper while the music is playing and
when it stops, the lucky students will
peel off the paper and answer the
question.

Are you ready?

Yes Ma’am
(the teacher will draw a name)

____, it is largest among these three

kinds of space rocks. This chunk of
rock circle the sun in asteroid belt Asteroid

That’s correct, please draw a name.

______, What is the difference
between meteoroids, meteor and a
meteorite?
Meteoroids are small rocks or debris in space,
meteors are the visible streaks of light that
occur when meteoroids burn up upon entering
the Earth's atmosphere, and meteorite are the
solid pieces of meteoroids that have survived
their passage through the Earth's atmosphere
and have landed on the surface.

What is the biggest known asteroid?

Ceres is thought to be the largest asteroid in
our solar system.

What is a meteor?
Meteors are small bits of rock or dust that
enter the Earth's atmosphere and burn up,
creating a bright streak of light in the sky,
known as a meteor or a shooting star.

What are the parts of a comet?

The parts of the comet are the nucleus, coma,
dust tail and head tail
