Tick the correct answer.

(a) The planet known as the “Earth’s Twin” is

(i) Jupiter (ii) Saturn (iii) Venus

(b) Which is the third nearest planet to the sun ?

(i) Venus (ii) Earth (iii) Mercury

(c) All the planets move around the sun in a

(i) Circular path (ii) Rectangular path (iii) Elongated path

(d) The Pole Star indicates the direction to the

(i) South (ii) North (iii) East

(e) Asteroids are found between the orbits of

(i) Saturn and Jupiter (ii) Mars and Jupiter (iii) The Earth and Mars

 

Prepare a chart of the solar system.

2. During a vacation visit a planetarium and describe your experience

in the class.

3. Organise a quiz contest on the earth and the solar system.


 

FOR FUN

1. The sun is commonly known as Soorya or Sooraj in Hindi, Find out its

name in different languages of our country. Take help of your friends,

teachers and neighbours.

2. You might have heard that people make human chains and run for world

peace etc. You can also make a human solar system and run for fun.

Step 1: All children of your class can play this game. Assemble in a big

hall or on a playground.

Step 2: Now draw 8 circles on the ground as shown in the figure drawn on

the opposite page.

Use a 5-metre long rope. Mark at every half a metre with a chalk or

ink. Place a small nail to mark the centre. Now hold one end of

the rope at the central position. Ask your friend to hold a chalk

at the ½ metre mark and move around the nail holding rope and

chalk together on the ground.

You have drawn one circle just as you do on paper using a compass

and a pencil. Draw other circles in the same manner.

Step 3: Prepare 10 placards. Name them as Sun., Moon, Mercury, Venus,

Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Step 4: Select 10 children in the following order and give each one of them

a placard.

Order of placard distribution

The Sun - tallest, The moon - smallest; Mercury, Mars, Venus and Earth

(almost equal heights); Neptune, Uranus, Saturn and Jupiter taller than

the earlier four planets but smaller than the Sun.

Now ask the children holding placards to take their places with the Sun in

the centre in their orbits. Ask the child holding the moon placard to keep

the hand of the child holding the earth placard always.

Now your Solar System is almost ready to go into action.

Now make everybody move slowly in the anti-clockwise direction. Your class

has turned into a small human replica of the solar system.

While moving on your orbit you can also turn around. For everybody the

spin should be anti-clock wise except for Venus and Uranus who will make

the spin in the clock-wise direction.
