Assertion Reason Questions

Q. 1. Assertion (A): The Moon has phases due to its varying positions relative to the Earth and the Sun.
Reason (R): The phases of the Moon are caused by the changing angles of sunlight as the Moon orbits the Earth, resulting in different portions of the Moon being illuminated.
(a) Both Assertion and Reason are correct, and Reason is the correct explanation for Assertion.
(b) Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion.
(c) Assertion is correct, but Reason is incorrect.
(d) Assertion is incorrect, but Reason is correct.

Ans. Option (a) is correct.
Explanation: The Moon does have phases because its position relative to the Earth and Sun changes, which affects how much of the Moon’s surface is visible from Earth. The phases of the Moon are indeed due to the changing angles of sunlight as the Moon orbits Earth, leading to varying visibility of its illuminated portion.

Q. 2. Assertion (A): Stars appear to twinkle more than planets when observed from Earth.
Reason (R): The twinkling of stars is caused by the turbulence in Earth’s atmosphere, which causes varying amounts of starlight to reach the observer.
(a) Both Assertion and Reason are correct, and Reason is the correct explanation for Assertion.
(b) Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion.
(c) Assertion is correct, but Reason is incorrect.
(d) Assertion is incorrect, but Reason is correct.

Ans. Option (a) is correct.
Explanation: Stars do appear to twinkle more than planets when observed from Earth. The twinkling of stars is indeed due to the turbulence in Earth’s atmosphere, which affects the light from stars. Planets usually appear steady because they are closer and their light is less affected by atmospheric turbulence.

What is Assertion Reason Question for Class 6 Science?

Assertion-Reason Questions are a type of objective question where students are given two statements:

1. Assertion (A) – A factual or conceptual statement related to the topic.
2. Reason (R) – An explanation or justification for the assertion.

Students need to evaluate both statements and select the correct option based on their relationship.

Answering Format

Typically, the answer choices are:

1. Both A and R are true, and R correctly explains A.
2. Both A and R are true, but R does not explain A.
3. A is true, but R is false.
4. A is false, but R is true.

Best Ways to Prepare for Assertion Reason Questions

Assertion-Reason (A-R) questions test conceptual understanding and logical reasoning. Here’s how you can effectively prepare for them:

1. Strengthen Conceptual Understanding

• Read NCERT and reference books thoroughly.
• Understand key concepts, definitions, and principles in each chapter.
• Use mind maps and flowcharts for quick revision.

2. Focus on Cause-Effect Relationships

• Identify if the Reason correctly explains the Assertion.
• Ask yourself: Does R provide a valid explanation for A, or is it just another true statement?
• Practice linking concepts to real-life examples.

3. Practice with Assertion-Reason Questions

• Solve chapter-wise A-R questions from textbooks, sample papers, and previous years’ papers.
• Attempt mock tests and quizzes to improve accuracy.

4. Use the Elimination Technique

• If either A or R is false, eliminate options 1 and 2.
• If both A and R are true, check if R correctly explains A.

5. Improve Logical Reasoning Skills

• Understand different types of reasoning (scientific, mathematical, logical).
• Read explanations carefully and analyze the connection between statements.

6. Regular Revision

• Revise key concepts regularly to strengthen memory.
• Create short notes or flashcards for quick recall.
