Beyond Earth – Q&A for Class 6

1. Match the column:
Column I: (i) Satellite of Earth (ii) Red planet (iii) Constellation (iv) Planet commonly called an evening star
Column II: (a) Orion (b) Venus (c) Mars (d) Moon

• (i) Satellite of Earth → (d) Moon.
• (ii) Red planet → (c) Mars.
• (iii) Constellation → (a) Orion.
• (iv) Evening star → (b) Venus.

This match shows which item from Column II goes with Column I correctly.

2. (i) Solve the riddle:
"My first alphabet is in MAN but not in CAN My second alphabet is in ACE and also in FAN My third alphabet is in RAT and not in CAT My fourth alphabet is in SUN but not in FUN I am a planet that moves around the Sun."
(ii) Make two similar riddles by yourself.

(i) Answer: The letters spell M-A-R-S, so the answer is Mars.

(ii) Riddle 1: "My first is in STAR but not in SAT; my next in MOON and also in FOOD..." Riddle 2: "My first is in EARTH but missing in HEAT; my next in WIND and in KIND..."

These simple riddles follow the same pattern as the given one.

3. Which of the following is not a member of our Solar System?
(i) Sirius
(ii) Comets
(iii) Asteroids
(iv) Pluto

Answer: Option (i) Sirius. Sirius is a star, not a member of our Solar System.

4. Which of the following is not a planet of the Sun?
(i) Jupiter
(ii) Pluto
(iii) Neptune
(iv) Saturn

Answer: Option (ii) Pluto. Pluto is now classified as a dwarf planet.

5. Which is the brighter star, the Pole Star or Sirius?

Answer: Sirius is brighter than the Pole Star. It shines with more intensity and is visible from many areas on Earth. Its brightness makes it easily noticeable.

6. An artist’s representation of the Solar System is shown in Fig. 12.12. Is the order of the planets correct? If not, write the correct order.

Answer: The order is often incorrect. The correct order from the Sun is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. This order reflects increasing distance from the Sun accurately.

7. In Fig. 12.13, identify the star groups:
- The Big Dipper
- The Little Dipper
- Also, label the Pole Star.

• Connect the stars to form the Big Dipper shape.
• Connect stars to form the Little Dipper.
• Mark and label the Pole Star clearly.

8. In Fig. 12.14:
- Draw lines to connect the stars for Orion.
- Label the star Sirius.
Learning further: Also explore planet names in your language and visit a planetarium if possible.

• Draw Orion by connecting its main stars.
• Label Sirius in the drawing.
• Explore local names and stories about stars.

9. Stars fade away at dawn and appear at dusk. Why don't we see them during the day?

The brightness of the sun makes the sky too bright, so the stars become invisible during daytime.

10. Observe the Big Dipper 3–4 times over a clear night and locate the Pole Star. Does the Big Dipper seem to move? Sketch its change, noting the time.

As the Earth rotates, the Big Dipper appears to move across the sky. Its position shifts with time, showing a gradual movement.

11. Think about the night sky and write a poem or story on it.

I wrote a short poem about twinkling stars, the shining moon, and endless dreams that sparkle in the dark night sky.
