This document outlines a lesson plan about the layers of the sun. It identifies four main layers: the photosphere, convection zone, radiation zone, and core. The photosphere is the sun's surface and outermost layer with a temperature of 6,600°C. The convection zone transports energy outward through convection currents. The radiation zone emits radiation, while the core is the innermost part composed of molten rock where hydrogen is converted to helium. The lesson uses activities like labeling diagrams and models to help students understand and describe each layer of the sun.

1. I. OBJECTIVES

A. Review
Good morning class!
What have we discussed last time?
What is a solar system?
Will you enumerate the members of our
solar system?
I think you are now ready to our new
lesson for today.
2. LessonProper
A. Motivation
Good morning Sir Art!
We discussed about the members of the
solar system.
It is the sun, planets and all other heavenly
bodies orbiting our sun.
The members of our solar system are the
sun, eight planets, dwarf planets, asteroid,
meteor, comets

2. I have here a two pictures of heavenly
bodies.
What can you see in these picture?
Will you describe the sun based from the
picture you saw?
How about the Earth?
B. Presentation of the Lesson
Today we will be dealing with sun.
C. Unlocking of Difficulties
Before we formally start our new lesson for
today, let us first unlock words that we
might surely encounter during our
discussion.
I have here a planetary orbit, each orbit
consists of a word.
You will pick a word from the orbit and
place to its correct meaning.
Is it clear?
The sun and the planet Earth.
Hot ball of heavenly body.
Ball of rock and ocean.
Yes sir.

b. a star where planet orbits.
c. mass of gas in space.
d. flame form at the surface of the sun.
e. level or parts.

3. D. Development of the Lesson
Do you think sun is a star?
What makes you think that sun is a star?
This time, I will show you a videoclip about
our sun as a star.
(Teacher will show the videoclip)
From the video you have watched, is our
sun the largest star?
What is the largest known star?
How do you describe the size of our sun as
compared to other star?
Let’s study this picture.
What can you see in the picture?
Will you enumerate the layers of the sun?
Will you describe the photosphere?
What is a corona?
How a sunspot form?
Another layer of the sun is the convection
zone. Will you describe this layer?
Yes sir.
Because just like star, sun is a ball of
hydrogen and helium gas that emits light
and heat.
No sir.
VY Canis Majoris
Our sun is a medium or average-sized star.
The layers of the sun.
The photosphere, convection zone, radiation
zone and the core.
It is the surface and outermost layer of the
sun with a temperature of 6,600oC. This is
where we can see sunspots and corona.
It is a solar flare formed at the surface of the
sun.
When a sudden eruption in the photosphere
happens known as corona, underneath form
a dark, and cooler space known as sunspot.
Convection zone is the second outer-most
layer of the sun which energy is transported
outward mainly by convection currents.

4. What is the importance of this layer?
The next layer is the radiation zone.
How do you describe this layer?
Why living things on earth doesn’t affect
much by the radiation of the sun?
The last layer of the sun is the core.
How do you describe this layer?
Which is hotter, the core or the
photosphere?
Let’s have an activity.
I have here a boiled eggs.
Let’s imagine that this egg is the sun.
Who will go infront and show to us the
layers of the sun using an egg?
Another thing that could represent the sun is
an apple.
The convection zone is responsible for
formation of cloud in the earth and on other
planets in the solar system.
Radiation zone is the third other-most layer
of the sun that emits radiation which is
dangerous to our health.
Because radiation zone and the photosphere
lessen the effect of radiation by blocking
some of the radioactive particles that the
radiation zone releases.
Core is the inner-most and the center part of
the sun. It is mainly compose of molten
rocks where hydrogen is converted to
helium to produce energy in the form of
heat and light.
The core, because it has a temperature of 15
million degree Celsius, while photosphere
has only 6,600 degree celcius.
The eggshell represents the photosphere, the
cloth-like part between the shell egg white
is the convection zone, the egg white is the
radiation zone, and the egg yolk is the core.

5. Who will go infront and show to us the
layers of the sun using an apple?
E. Generalization
Will you enumerate the layers of the sun?
What our sun is considered as star?
F. Enrichment Activity
Draw the cross section of the sun showing
its layers and label its parts.
Who will go infront and explain his work to
us?
The red skin of the apple us the
photosphere, the white portion after the skin
is the convection zone, the round space at
the center is the radiation zone and the seed
is the core.
The layers of the sun are photosphere,
convection zone, radiation zone, and the
core.
Because just like other stars, our sun is a
ball of hydrogen and helium gas that emits
light and heat.
This is the sun. The sun has four layers.
Core is the center, radiation zone is the
second inner-most, convection zone is the
third inner-most, and the photosphere is the
outer-most layer.
