In this interactive and informative presentation, 8th-grade students will explore the fascinating members of our solar system and learn about the crucial role artificial satellites play in space exploration. From the blazing sun to the mysterious outer planets, students will embark on a journey through the cosmos, discovering each celestial body's unique characteristics and features. Through engaging visuals and interactive activities, students will gain a deep understanding of the wonders of our solar system and the important tools used to explore it.

SYSTEM

2. Let’splaya Game!

3. 1. Will show some images.
2. Each of the images has
a pool of letters in it.
3. Have to form a suitable
word from the image.
4. Only have 10 seconds to
guess the answer.

5. ANSWER: ASTERIODS

7. ANSWER: COMETS

9. ANSWER: METEORS

11. ASTEROIDS
 There is a large gap in between the orbits of Mars and Jupiter.
 This gap is occupied by a large number of small objects that
revolve around the Sun. These are called asteroids.
 Asteroids can only be seen through large telescopes.

13. Comets
 Comets revolve around the Sun in highly elliptical orbits.
 However, their period of revolution round the Sun is usually very long.
 A Comet appears generally as a bright head with a long tail.
 The length of the tail grows in size as it approaches the sun.
 The tail of a comet is always directed away from the sun.
 Many comets are known to appear periodically. One such comet is Halley’s
comet, which appears after nearly every 76 years.
 It was last seen in 1986.

15. METEOrS
 bright streaks of light in the sky.
 These are commonly known as shooting stars, although they are not stars. They are called
meteors.
 A meteor is usually a small object that occasionally enters the earth’s atmosphere.
 At that time it has a very high speed.
 The friction due to the atmosphere heats it up. It glows and evaporates quickly. That is why the
bright steak lasts for a very short time.
 Some meteors are large and so they can reach the Earth before they evaporate completely.
 The body that reaches the Earth is called a meteorite.
 Meteorites help scientists in investigating the nature of the material from which the solar system
was formed.

18. Introduction to artificial satellites
1. Name of first Indian artificial satellite launched in space.
Ans: Aryabhatta
2. Name of the Earth’s natural satellite.
Ans: Moon
3. Which 2 planets do not have satellites orbiting them?
Ans: Mercury and Venus
4. _______________ are used to collect information about other planets,
stars, galaxies, etc…
Ans: Artificial Satellites

19. Artificial satellites are man-made. They are launched from the Earth. They
revolve around the Earth much closer than earth’s natural satellite, the moon.
India has built and launched several artificial satellites. Aryabhatta was the first
Indian satellite. Some other Indian satellites are INSAT, IRS, Kalpana-1,
EDUSAT, etc… Artificial satellites have many practical applications. They are
used for forecasting weather, transmitting television and radio signals. They are
also used for telecommunication and remote sensing.

21. Conclusion
1) Comets are celestial bodies that orbit around the sun. they are made up of a mixture of
ice, rock and iron.
2) Comets take 200 years or more to complete one revolution around the sun.
3) Comets glow when they are very near to the sun.
4) Asteroids are tiny broken pieces of planets
5) Asteroids are found in the asteroid belt in between Mars and Jupiter.
6) An asteroid or a part of an asteroid that burns after entering into Earth’s atmosphere is
called a meteor.
7) Meteors burn up completely before hitting the ground, and if they don’t are called
meteorites.
8) A meteor shower is a phenomenon in which particles from comets enter into the Earth’s
atmosphere and a swarm of meteors is seen.

22. 9) Artificial satellites are human-built objects orbiting the earth and other
planets in the solar system.
10) Aryabhatta was the first satellite launched by India.
11) Satellites are used for various purposes like :-
o In telecommunication
o In weather forecast
o To gather information about other objects in space
o To locate minerals and study agricultural yields
o In remote sensing & navigation
