# Solar System (Sun and Planets)

#### Students’ Learning Outcomes

● Describe the Solar system and its planetary arrangement showing position of the Earth in our solitary system.

● Explain the relative sizes of the Planets and their distances from the sun using a model.

Information for Teachers                                                                                                                           We live on the

There are 8 planet including Earth revolving around the Sun and from our solar system.

The Planets of our solar system are named as, Mercury, Venus, Earth, Mars,                          Jupiter, Saturn, Uranus and Neptune in order of the distances from the Sun.

While teaching the Lesson, the teacher should also consult textbook at all steps                                                                                                   where and which applicable

#### Material/ Resources

An unlabelled and a labeled chart of Solar system, Two sets of 8 pieces of small   cards with names of planets, glue, a long string, paper clips.

# Worm up Activity

Ask the students, ‘What is the name of our planet?’ (Students response: Earth)
Inform them that there are seven other planets revolving around the sun like Earth.
Display the labeled chart of the solar system and ask the students to observe it carefully.
→ Where is the Sun located in the solar system? (Students response: In the center of the solar   system)

→ How many planets are there in our solar system? (Students response: Eight)
→ Which is the largest planet? (Students response: Jupiter.)
→ Which planet is the nearest to the Sun. (Students response: Mercury)
→ Which is the farthest planet of Solar system. (Students response: Neptune)
→ At what position from the sun our Earth lies? (Students response: At the third position)

#### Development

Activity
Make small cards of names of the planets.
Replace the labeled chart by an unlabelled chart of the Solar system.
Call any 8 students one by one. Provide the students the small cards of the names of Planets.
Instruct them to identify a Planet and past the sticker of its name near that planet.
Direct the other students to observe and help to locate the correct positions.
Conclude at the end that he planets remain in the same arrangement with respect to each other.

# Activity         Eight round shaped objects of different sizes. For example, a pea for Mercury, a small            For Venus, a large walnut for Earth, a playing marble for Mars, basketball for Jupiter, a football for Saturn, a grape fruit for Uranus and a tennis ball for Neptune.

Divide the class into eight possible groups.
Assign one of the round shaped objects to the each group.
Ask the groups to arrange their objects on the table according to the relative sizes.

#### Activity: 3

Write the name of the planets on the board in order of their position.
Ask every students to recall again and again and learn the names properly.
Assign one of the round shaped objects to each group.
Ask the group to arrange their objects on the table according to their relative sizes.

#### Assessment

What a planet’s orbit looks like?   (Oval shape)
In your opinion, which one could be the warmest planet in our solar system? (Mercury)
As regards the sizes of planets, how large is our Earth? (Fourth large planet)
Teacher is also required to involve the students in solving the problems given in the exercise at end of unit/ chapter.

#### FOLLOW UP / HOME WORK

Ask each student to prepare a big chart having almost all the information about the solar system with respect to sizes and relative distance.
