Objective Infer that the sun is the center of the solar system.

Objective Name the planets and other heavenly bodies in the solar system.

Objective

Describe

the sun.

ObjectiveThank God for the sun that gives us energy.

Question What rises

in the morning and sets in

the afternoon?

Group work

Question What do you know about the sun? Where it is in the solar system? What it is made of?

Reporting

Sun

Is the center of the solar system

I wondered why there are objects in space?How did the sun and other member of the solar system begin?How were they formed?

About 4.6

billion years ago, a giant cloud of gas and dust collapsed due to powerful force called GRAVITY.

One of the region of the collapsing cloud

formed a huge , spinning ball.

Because of the tightly packed gases, the center of the huge spinning ball became so hot that

it started to glow.

This gave birth to a very bright star called SUN.

Sun Is a star

A giant ball of hot glowing gas

Sun Gases are so hot

that they burn and give off light

Heat and light from the sun travel from the sun in space

Sun•Its family is called solar system

•Includes the nine planets

There are two main classes of planets in the solar system – _ _ _ _ _ _ _ (oussega) and _ _ _ _ _ _ _ _ _ _. (rrestetial)

Gaseous planets - have strong gravity due to their great mass

- enable to hold gas particles like hydrogen and helium

- Jupiter, Saturn, Uranus,

and Neptune

Terrestial planets

- it is also called as rock planet

- have weaker gravity so they do not have the ability to hold hydrogen and helium

-Mercury, Venus, Earth, and Mars

Sun

•Includes themoon

Earth- is the only planet with one

moon

- Jupiter with four moons

- other planets like Mercury and Venus have no moons at all

- planets with ring are Jupiter, Saturn, Uranus, and Neptune

Sun•Includes the asteroids, meteors, and

comets

Aside from planets there are other objects that move around the sun.

* They can be seen through a TELESCOPE, an instrument that allows a person to see distant objects. Among these heavenly objects are ASTEROIDS, which are rocky objects orbiting the sun. They have elliptical orbits that enable them to revolve around the sun.

They can be found between Mars and Jupiter, in a region called asteroid belt

Meteoroids o pieces of rocks or metal-like objects moving through the space

o Once they enter the Earth’s atmosphere they become meteors or shooting stars

o They heat up and appear

to glow brightly when seen

from the ground.

Comets Make up the last group of heavenly bodies They are relatively small, icy bodies that move

around the sun When they are near the sun, some of the ice on

the comets turn into gases. The gases and dusts releases from the ice

develop into long , bright tails.

Sun•Each member of the solar system follow a certain path or orbit

•Nearest star to earth

Earth-It is called the living planet

-is the only planet that supports life

- its temperature and atmosphere allow water to exist as solid, liquid, and gas

- it has enough oxygen and water for all living things to survive

Sun Provides the earth

with heat, light and energy

Gives life to human beings,plants, and animals

Identify the nine planets and other things in the solar system

Activity

Study the model / illustration of the solar system.

a. Observe the sun very early early in the morning and at noon time . Use dark

glasses.

b. stay under the sun for five minutes.c. feel your head and skin.

Try this

Try This What to know:

1. what compose the solar system?

2. what is the sun? What to use model of the solar

system smoke glass

What did you learn?1. What is the center of the solar system?2. What is the first four planets?3. What are the last five planets?4. What planet where we live in?5. What other things are there in the solar system aside from the planets?6. How do the members of the solar system move around the sun?7. Name the six members of the solar system?8. Describe the sun.9. How did your head and skin feel when you were under the sun?10. Where did the heat come from?11. What does the sun give?

Discussion

Generalization The sun is made up of very

hot gases which give heat and light.

The sun is the center of the solar system.
