A. Preparatory Activities
Teacher’s Activity
1. Prayer
2. Greetings
3. Energizer
4. Checking of Attendance
Class monitor, who is absent from the
boys?
How about from the girls?
5. Checking of Assignment
What was your assignment all about?
Students’ Activity
Our assignment was to master the
performance task assigned to each
group.
(presentation of assigned task per
group)
6. Review
What was our last topic all about?
Our topic was all about El Nino and La Nina.
What is El Nino?
El Nino got its name because it starts to
happen during or after the Christmas
season. El Nino means “Christ the Child”.
This natural phenomenon occurs at regular
interval of two to seven years and last for
nine months or two years at most.
This starts when trade wind is weakened, it
causes the piling up of warm surface water
and making the part of the Pacific Ocean
warmer. Since our country is near the
Pacific ocean, we can experience this
natural phenomenon.
How about La Nina?
B. Lesson Proper
1. Motivation
Class, I have here a picture.
(Picture is all about some famous stars).
Class what can you say about the picture?
2. Presentation
This phenomenon is being triggered by the
cooling of the eastern part of the Pacific
ocean. That’s why it is called “Cold Pacific”.
La Nina may last for nine to twelve months
and in some cases it lasts for two years.
.
Students may answer:
I can see stars with different sizes.
Stars possess different colors from
each other
Our topic for today is all about the characteristics of the
stars.
Let us do the Activity 1 “ Characteristics of Stars”
Part B.
(After the activity is finished, students will watch the video
all about the characteristics of stars.)
(Students watch the video).
3. Discussion and Analysis
Based on the video I presented and the activity you
made, have you gain a lot of ideas regarding about the
characteristics of stars?
Yes.
When we look at the night sky, we see thousands of
stars and these stars differ in many ways. Such ways are
sizes, brightness and color.
Let us start with the sizes of the stars.
Based on the video, does the sizes of the stars, differ in
each other?
How about the color of the stars?
What are the colors the stars possess?
Does the color of the stars has relationship to its
temperature?
Yes.
Stars vary in terms of their sizes. One
known largest star is the Antares and
Betelgeuse which fits thousands of sun
in it.
Some other are smaller than the sun
which is actually the size of our planet
Jupiter.
Stars also vary in the color it
characterize.
Stars color maybe red, orange, yellow,
white and blue.
Yes
Can you state the order of the star’s color in terms of their temperature?
What color is the coldest among them all?
How about the hottest?
How about the color of our Sun?
Red, orange, yellow. white, blue
Red
Blue
Yellow.
Next characteristics of stars is in terms of their brightness,
Based on the activity, what have you observed?
We observed that the distance and its
actual brightness affects the brightness
of the star.
What do you call for the apparent brightness?
Apparent brightness refers to
brightness of the star depending on
how far is that star from the Earth.
In apparent brightness, the farthest
star from the Earth would possess
lesser brightness compared to those
nearest from the Earth.
How about the absolute brightness?
Absolute brightness is the brightness
of the star if all the stars were the
same standard distance from Earth.
4. Generalization
What are the characteristics of the stars?
Characteristics of stars are in terms of
their sizes, color and brightness.
Can you state the order of the color of the star in terms of their
ascending temperature?
Red, orange. Yellow, white and blue.
Distance and actual brightness.
What are the two factors affecting the brightness of the star?
What is apparent brightness?
How about absolute brightness?
Apparent brightness refers to
brightness of the star depending on
how far is that star from the Earth.
In apparent brightness, the farthest
star from the Earth would possess
lesser brightness compared to those
nearest from the Earth.
Absolute brightness is the brightness
of the star if all the stars were the
same standard distance from Earth.
5. Application
Group Activity
I have here prepared an activity. What you are going to do is to
rank the star in terms of its size and color in ascending order and
its apparent brightness.
(I will present the materials)
(Students will do the activity)
