Practice questions
Q1What is the safest RBSE boundary for this topic?
A Solar system, Moon and stars, Sun and planets, comets and constellations
B Black holes, pulsars, relativity and radio telescopes
C Only rockets, astronauts and space-station engineering
D Only Earth’s atmosphere, rocks and water cycle
Explanation The RBSE PDF line itself is the anchor, so the option that preserves Moon, stars, Sun, planets, comets and constellations is correct. Asha should not expand the answer into every exciting astronomy topic because REET asks from the listed boundary.
Q2In the safe REET order of the eight planets from the Sun, which sequence is correct?
A Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus, Neptune
B Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
C Venus, Mercury, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
D Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, Neptune
Explanation The eight-planet order from the Sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The wrong choices disturb this order by swapping nearby planets.
Q3Which statement best describes the Universe for a REET Level-2 science question?
A Only the Sun and the eight planets
B All space, matter, energy, stars, galaxies and the solar system together
C Only the stars that are visible to the naked eye at night
D Only the planets and moons that move around the Sun
Explanation The Universe means all space, matter and energy, including stars, galaxies and our solar system. Options limited to planets, moons or visible stars confuse a part of the Universe with the whole.
Q4Why should the teacher call Meena’s planet drawing a memory map rather than an exact distance map?
A Because one page cannot show real planetary sizes and distances accurately together
B Because all planets are actually equally spaced from the Sun
C Because planet order has no value in upper-primary science
D Because diagrams are never allowed in science assessment
Explanation Meena’s drawing can help memory, but it cannot carry exact scale. The best teacher response keeps the learner’s effort and adds the scientific caution about distance and size.
Q5Which statement correctly defines a planet in the solar-system context?
A A body that moves around a star and is seen mainly by reflected light.
B A self-luminous body that produces its own light and heat.
C A group of stars that appears to form a pattern in the sky.
D A small icy body that may form a tail near the Sun.
Explanation A planet moves around a star and is visible mainly because it reflects light from that star. A self-luminous body is a star, a star pattern is a constellation, and a small icy body with a possible tail is a comet.

6Which pair is correctly matched?
AUniverse - Only the Sun's planets
BComet - Apparent pattern of stars
CLunar eclipse - Moon between Sun and Earth
DSolar system - The Sun and bodies gravitationally linked with it
7A student says, "A comet is just a group of stars that looks like an animal." Which correction is scientifically accurate?
AA comet is a small icy body that may show a coma or tail near the Sun; a star pattern is a constellation.
BA comet is a fixed star pattern, and a constellation is one icy body.
CA comet is a planet because it moves around the Sun and shines brightly.
DA comet is a natural satellite because it moves around Earth.
8Consider the statements about sky objects. I. The Universe includes the solar system. II. A comet is an apparent pattern of stars. III. A constellation is one small icy body. How many statements are correct?
AOnly one
BOnly two
CAll three
DNone
9Imran says the Moon is a star because it shines at night. Which correction is best?
AThe Moon is a planet because every round object is a planet
BThe Moon is Earth’s natural satellite and reflects sunlight
CThe Moon is a comet because it appears to change shape
DThe Moon is a constellation because many people see it at night
10Read the two statements. Statement I: A solar eclipse occurs when the Moon comes between the Sun and Earth. Statement II: A lunar eclipse occurs when the Moon comes between the Sun and Earth. Which option is correct?
ABoth statements are correct.
BOnly Statement II is correct.
CBoth statements are incorrect.
DOnly Statement I is correct.
11Which teacher response best supports a learner who cannot join the courtyard sky walk?
ARemove the learner from the activity and give a worksheet later
BMake the learner recorder, timekeeper or model controller with peer support
CSkip sky observation for the whole class whenever one child has difficulty
DAsk the child to memorise all planet names silently instead
12A teacher gives cards named Sun, Earth, Moon, comet and Orion to sort under star, planet, satellite, small icy body and constellation. Which matching is scientifically correct?
ASun-planet; Earth-star; Moon-comet; comet-satellite; Orion-constellation
BSun-star; Earth-planet; Moon-satellite; comet-small icy body; Orion-constellation
CSun-star; Earth-satellite; Moon-planet; comet-constellation; Orion-small icy body
DSun-constellation; Earth-planet; Moon-star; comet-small icy body; Orion-satellite
13A student draws the Sun and all eight planets at equal gaps on one page. What is the best scientific teacher response?
AMark it completely correct because every diagram may ignore distance.
BReject the drawing because planets cannot be shown on a page at all.
CCall it a memory map, explain that real distances are not equal, and then ask for the order from the Sun.
DTell the student that equal gaps prove all planets take equal time to orbit the Sun.
14How many planets are counted in the solar system from Mercury to Neptune?
15In a class discussion, Asha says, "The Moon is a star because it shines." What is the best assessment use of this response?
AIgnore it because misconceptions should not be discussed in science class.
BMark it wrong and immediately move to the next learner.
CTreat it as proof that the child has not observed the sky carefully.
DUse it to probe the idea that brightness means self-made light, then clarify reflected sunlight.
